Nvenc vs cpu encoding. 265 as well as resolutions up to 8K are supported.

Nvenc vs cpu encoding The 1080ti encoding still much quicker than CPU. No quality increase past RF20 SSIM vs handbrake RF factor. You do have an option on where to Encode. I currently have a system with an i9-10850K, 16GB of DDR4 RAM, and a GTX 1660 Super, which encodes NVENC at 4K at about 21-25fps using Handbrake 1. Oct 8, 2020 · GPU encoding gets better every generation. It's a bit of a toss-up as to which one works quicker, as you've discovered. 4. And yes, I am aware I can just use CPU encoding. So there is no way of comparing as X264 and X265 are cpu encoding NVENC and AMD-VCE gpu encoding. You are confusing Encoding with Rendering. Note that "x265" is CPU only. i did some testing with 4k clips (raw quality) encoded to arc a380 qsv av1 and 4090 nvenc av1 vs hevc for both qsv and nvenc -- the average fps speed for av1 at best quality preset for both: nvenc 61. But NVENC is still better quality than CPU medium preset encoding. 5 fps and qsv 70 fps. Answers: Generally speaking, the priority of CPU encoding is quality while GPU encoding Although someone could download his source video and encode it with SVT-AV1 at a bitrate of 1380 Kbit and see how the VMAF compares to his values. NVENC on 20 series and newer cards under x. What we can otherwise learn is that RF factor has no incidence on encoding speed with NvEnc. Jan 21, 2021 · Convert videos fast with CPU/GPU Hardware Activated Hardware H264 encoder. But I did try to work something out for you: In terms of speed at default settings: NVENC > x264 > x265 NVenc was never meant to be an archival/production tool to begin with (at least as far as I know). You'll generally hear them named for the chip architecture - Turing, Ampere, Lovelace, etc. There was a rotating cube, that had jagged edges with the nvidia encoder. So, when it comes to picking the better encoding option for your next streaming adventure on Twitch, YouTube, Facebook Gaming, or even Kik, it’s pretty straightforward. But HandBrake x265 encoding takes too long. They are faster, meaning they have decent Real-time encoding performance. Is x264 still recommended for encoding films for offline playback? What are your thoughts? EDIT: Topic can be closed. Using nvenc is what prompted me to spend ridiculous amounts on SSD storage. 264 (downresizing to 444x250). Although compatible hardware was not available on the computer used in these tests, the Intel QSV hardware encoder performs similarly to VCE and NVENC, with Intel QSV producing slightly higher x265 is software encoding. I am fine if the difference is very small. Absolutely not, lol. 7 Mb/s. zip from BtbN I want to transcoding a h. As to what is better Quicksync vs NVENC, it totally depends on hardware generation, the content, and the options used. QSV is higher quality than nvenc and has way less performance impact on your system. CPU encoding is going to hurt performance. On the other hand, AMD has some catching up to do. Jan 2, 2023 · If you want to speed up the HEVC encoding on your computer, choose a hardware HEVC encoder such as AMD VCE, Intel QSV, and NVIDIA NVENC. What you see in the preview in OBS it's not the real output but the real view of the program. NVENC is hardware. Try having a graphical overlay of your frame times while playing a game with either encoding option and see for yourself whether the timings stay reasonably stable. There is no reason to fight using NVENC for realtime encoding/ gaming+streaming scenarios. When I get the library converted I'll likely switch to CPU only encoding. Jan 27, 2025 · NVIDIA GPUs - beginning with the Kepler generation - contain a hardware-based encoder (referred to as NVENC in this document) which provides fully accelerated hardware-based video encoding and is independent of graphics/CUDA cores. As far as hardware encoders go, NVENC is the best one, Intel Quicksync and AMD encoder produce lesser quality for same bitrate. For HEVC encoding, the 12900K CPU encoding was Even with an i9 10980XE, encoding a 2 hour 4K video takes a day at a time on CPU at the slow preset. It'll take longer, but you'll get a better quality-to-size ratio. This is important for Twitch HEVC - Nvenc is again king, but QSV and AMD are a close second. Compare comparable encoding settings between NVENC and x264 in offline renders. NVENC is nvidia’s encoder which can only encode h264. Nvenc prioritizes speed at the expense of visual fidelity. So if you're doing something offline, and the your output file is the final version (ie. 4-latest-win64-gpl-4. CPU or GPU encoding, which should I use?" - from Reddit . We already knew that NvEnc is quicker than x265, but we will need these numbers later. 4K encoding is too heavy a workload for a typical CPU setup, but the GA10x NVENC encoder makes high resolution encoding seamless up to 4K on H. yeah. 265 This video literally talks about the encoding presets for CPUs all being less quality than NVENC. But the difference is like 0. In 20 series Nvidia did a big jump in nvenc and it continued in 30 and 40 series. The key difference is the time it takes to encode and the file size of the finished product. 265 10-bit NVENC Constant Quality: 20 CQ Encoder Preset: Slow Encoder Profile: Main 10 Encoder Level 5. All moderns gpus now support video hardware encoding which encodes h. If you have a different CPU already, Ampere is noticeably better quality than AMD's current offerings, and also Ampere is significantly higher performance in productivity work, due to having 2xFP32 performance, so the 3070 I have a laptop RTX 4090, and was curious if nvenc AV1 encoding could match CPU encoding. – Start encoding. The result rendering with both CPU and NVENC looks just as good as x264/x265 but renders almost twice as fast. CPU Encoding using 14900F with limit to around 100 W for power effience NVENC using 4080super when I observing its around 40 -60 w Both are software detect reading, I assume the Actual Power usage will be 20% more Encoding Methods: NVIDIA NVENC (GPU-based encoding) Preset: Slowest mode Bitrate: 2000 kbps Output file size: 690 MB Jul 7, 2022 · CPU encoding is still the cleanest at any given bitrate, but especially at low bitrates. – Intel QSV and Nvidia NVEnc are hardware encoders. Like if you record at 15mbps you're probably not going to tell TLDR GPU for speed, CPU for quality but only at a low enough bitrate to actually see it. You've discovered the main differences between CPU vs GPU. Encoding quality vs handbrake RF factor. The only advantage hw enc has is real-time performance. I understand that for any given CF level, I'll get much larger file using NVENC, but for now, for the purposes my library I'm ok with the quality I'm getting out of NVENC vs. 264 (x264) is better than nvenc/QSV (H264) and there is not much difference in terms of speed unless you have a very good Processor. (AMD) or (NVENC) or (QSV) are hardware encoders built into your GPU. Simply change the Output Mode to "Simple", select one of the available encoders and choose either the "High Quality, Medium File Size" or the "Indistinguishable Quality, Large File Size While nvenc is visually a league above the others [e: hardware encoders], CPU encoding is still miles ahead of all of consumer-hardware encoding in terms of bitrate/filesize at quality parity. Jan 4, 2024 · Nvidia GPUs, such as those found in the P and G Amazon EC2 instances, include this kind of built-in hardware in their NVENC (encoding) and NVDEC (decoding) accelerator engines, which can be used for real-time video encoding/decoding with minimal impact on the performance of the CPU or GPU. Mar 16, 2019 · If you try to use nvenc make sure to give the nvcontainer. Did cpu x265 vs nvenc on my 3070. Like others pointed out, the library you use will dictate GPU vs. CPU encoding gives you smaller sizes but takes a lot longer to encode. x264 is fast enough on an 8-core CPU that it hardly pays off to go with a faster encode for offline movies. ALL hardware encoding is utter garbage for quality and file size, it's just fast and that's about the only benefit. Note that many of the people deep in CPU encoding employ multiple techniques to make their encoding as fast as possible: fully optimized binaries (native arch opts, O3 LTO and even PGO), chunked encoding to maximize thread scaling and a fully optimized OS flavor with performance governors for max speed. I've found NVENC HEVC better than QSV HEVC overall, but you should try with the best setting with nvenc and better setting for QSV to choose one or another. This minimizes the impact on your gaming performance. 265 mkv file (1920x1080) to h. 265/HEVC format. After some tinkering, I realized that if I kept all things the same but changed my encoder from NVENC HEVC (which I have been using from the beginning) to NVENC H. 264, and even 8K on HEVC. Why use you dgpu for encoding when you have a perfectly capable igpu that has a higher quality encoder thats doing no work anyways? Av1 > x264 very slow > qsv > Nvenc > AMF From best to worst quality at 2500/6000/8000kbps bitrate on average I don't think TV show DVDs are going to show you very much difference between CPU vs GPU encoding. To the best of my knowledge AV1 hardware encoding is available on Intel GPUs and the nVidia RTX 4000 series so I haven't had a chance to play with it yet. 1080p60 encodes under x264 on the 8700K under strict bencharking can't touch the NVENC output on your 2070. X264 will take more cpu overhead, but the files can be much smaller for a similar video quality. Even if you process lasso (set affinity) everything around to their own cores, the heat generated by encoding with the cpu (at the same quality that you can get with NVENC max quality), will affect the cpu speed/performance. 5 GB Overall bit rate: 21. Jul 22, 2020 · Currently the common codecs H. 264 is x264 (CPU encoding) and NVENC (hardware encoding) H. x264 is a software encoder (encoding on the CPU) whereas NVENC (nVidia), QSV (Intel) and VCE/AMF (AMD) are (dedicated) hardware encoders (encoding on the GPU). Jan 11, 2022 · NVIDIA's NVENC encoder is supported on Windows and Linux. CPU only rendering died a long time ago. 264(NVEnc) encoder, my CPU is still at a 100% usage in the task If I'm encoding a "reasonably modern" movie, the NVENC-encoded result is usually only slightly bigger - a size/bitrate tradeoff I'm willing to live with because of the massive encoding speed increase (I'm not super worried about disk space and the bitrate is still small enough where I can stream to remote devices when I'm on the road. ) Jul 22, 2020 · For some time now, a separate encoding chip, which Nvidia NvEnc has christened Nvidia NvEnc, has been used in many NVIDIA graphics cards. Quicksync is virtually the same type of stuff as NVENC, except quicksync uses integrated GPU for that. GPU encodeing lacks several other instructions that CPU encoding uses. But it was super obvious. The downside is that it takes more time to encode. May 18, 2022 · Firstly, my specs: I'm using a Alienware m15 r6 laptop, equipped with an i7-11800H and a RTX 3060 Laptop, 16GB RAM. 264 and H. Performance will be lower in your game than when using a dedicated encoder while gaming. I did a search here in the issues and do not see this discussed anywhere. The Nvenc encoder is aimed at streamers who need to encode as close to real-time as possible. NVENC is not really set up for encoding videos for offline playback. I want to use: CPU (Sandy Bridge supports h. For the most part, NVENC is better than any other realtime encoding option with a modern card and the right settings. It's a mediocre gaming+encoding CPU at best with only having 6 cores / 12 threads. And in terms of H. MacX Video Converter Pro is powered by both GPU Nvidia NVENC, AMD and CPU Intel Quick Sync Video to improve video decoding, encoding and processing speed up to 250-320FPS, 5X faster than others. I was using rigaya encoders for both. I'm well aware that encoders are just ASICs and don't really affect the GPU's performancee at all (having an entire 2nd GPU would probably hurt performance just from the heat) This is just about being able to use NVENC in OBS. This is important to me because I would like to encode while away from home with my laptop. Figure 1: NVIDIA NVDEC/NVENC architecture. The only exception would be if you always opted for the fastest possible software encode settings. 264) & Excellent (H. There's no synergy benefit for having both cpu and gpu from the same vendor for encoding as it will use either or. Software encoding doesn't use hardware acceleration. For reference, there 8 generations of NVENC hardware encoders at this point, with newer ones having different features and sometimes better encoding (eg - 8th gen NVENC used on the 4000 series includes AV1 encoding). the "x265" ones, generally when it starts with x, means it's the software encoding based encoder, using your CPU to render. What exactly is software encoding? Are you just saying to use CPU vs. Software encoding does not handle fast encoding, well. Nvidias hardware encoders are quite good however. Hey I recently built a JF server using the core i5 11400 and the transcoding performance is fantastic, though it did take me a while to get qsv to work on linux (). In this case I render to DNxHR because its fast and go work on other video and run ffmpeg for final encoding in background. When rendering videos, I have the option of using Nvenc (Nvidia GPU) or my CPU to do the heavy lifting. 265 video much faster than a CPU can. CPU. Whereas NVENC doesn't have all those advanced encoding options, but it's quite a bit faster. Even if you use x264. I currently have a bunch of video to encode using HandBrake, during the process, I discovered that even using H. Mar 26, 2024 · -c:v h264_cuvid is calling CUVID, which is slower and less efficient than NVENC. This is a real hardware solution that can convert videos quite… Well, not really. – Add the video file you try to encode to HEVC. . You may want to try CPU encoding for high-quality output and GPU encoding for efficiency and performance. Jul 22, 2020 · For some time now, a separate encoding chip, which Nvidia NvEnc has christened Nvidia NvEnc, has been used in many NVIDIA graphics cards. ” #streaming #nvidia #amdAfter using a couple different solutions for my Saturday stream I realized that I may have upgraded my PC into a streaming beast wrong Jan 26, 2015 · 2017 update: ffmpeg supports h264 and h265 NVENC GPU-accelerated video encoding. 3. 264 encoding is First of all, NVENC and x265 are two different encoder types. Can I get the same results as cpu encoding, target being 10bit x265, with NVENC, for say a A% higher file size, but done at Bx the speed? Jan 7, 2022 · I have an old i7-2700K, an old ASUS GTX 760 and last ffmpeg version ffmpeg-n4. Version of HandBrake available from the PPA that has NVENC/GPU encoding capabilities.

Jun 6, 2020 · After far too many requests to updated my previous X264 vs NVENC and NVENC vs AMF/VCE videos with newer AMD drivers, I've finally put together what I consider to be the ultimate package of encoder quality comparisons. Jun 8, 2024 · HandBrake includes support for hardware-accelerated encoding using NVIDIA’s NVENC technology, which leverages the GPU to speed up the encoding process. Superscale is always going to use the GPU. 1 is the current option in the Ubuntu 20. Quality and file size are sacrificed for speed. 265/HEVC format QuickSync is a software that uses the hardware inside your iGPU (the graphics part of your Intel CPU, not the "CPU" part of the CPU) to encode into H. Aug 17, 2018 · I've noticed that even with NVENC, my CPU (ryzen 2700x) is still hitting 100% usage, but it still faster. This can significantly reduce encoding Jun 26, 2020 · In this post, I’ll show how to use this feature in Handbrake and show some comparisons to illustrate the benefits and tradeoffs that result. With common Twitch and YouTube streaming settings, NVENC-based hardware encoding in GA10x GPUs exceeds the encoding quality of software-based x264 encoders using the Fast preset and is on par with x264 Medium, a preset that typically requires a dual PC setup. If you're talking about using it to re-encode files in non-realtime vs realtime transcoding through something like Plex, use CPU. 264, and that drops to 24–27 fps with HEVC encoding. Report this article Here is a test chart from a typical, quite modest desktop PC comparing x265 CPU encodings to HEVC NVENC GPU encodings: Hardware v Software encoding. The quality is visually identical at these settings. Gpu is also less efficient, meaning bigger files for the same quality. 265. The only real application where nvenc beats CPU encoding is high quality real-time capture / transcoding. As for quality: at low bitrates CPU > GPU encoding, but start going up and you're not going to be able to tell after a point. The Turing generation now promises video quality superior to that of classic CPU encoding with less system load. 265 MKV as the preset. what I'd like to know is the delta. You can do 1-pass or 2-pass encoding at the quality that you choose, for either hevc_nvenc or h264_nvenc, or and even with an entry-level GPU it's much faster than non-accelerated encoding and Intel Quick Sync accelerated encoding. x265 is always better if you don't need the speed of a hardware encoder. The delta may or may not be important enough to you depending on what you’re using it for, the quality level you want and how much you value the trade off between the much longer encoding times on a CPU gs a GPU. Check EposVox's AMF vs NVenc vs X264 vs X265 videos for more info in encoding performance. A 10 second 4k video on 4k output took about a minute to render on the CPU alone and about 40 with NVENC enabled. With end-to-end encoding offloaded to NVENC, the graphics/CUDA cores and the CPU cores are free for other operations. GPU (since I normally use Nvenc) Yes, using software running on the CPU, rather than the hardware encoder blocks on the GPU (supported by a bit of software). CPU will take forever to encode the same video in comparison, though. There will always be a performance loss, part of that is simply the load of running OBS and creating and or uploading video files. YMMV and it depends on your use case. Just to add what the other person said: When encoding you can often choose how much time the CPU is allowed to use. the file size. Nov 13, 2024 · CPU encoding tends to have better quality at the same bitrate, even on the 40 series. QSV is the best hardware encoding solution right now, and they've improved massively over the years. PSNR vs handbrake RF factor. Mar 31, 2022 · This dramatically lowers CPU utilization. Again, no quality CPU encoding is good to use it for final encoding - video is directly used without sending it to socials for later processing. I'm using Xeon 2191B with x265 SLOWER preset and 1080ti with x265 SLOWEST preset. So if I use regular x265 (not the 10-bit option) does that mean I'm getting a file that's technically not HDR? which could result in CPU having higher speed than GPU but for better quality. 264 and h. 265 encoding/decoding also via Quick Sync Video) for decoding and GPU for encoding (since my GPU card does not support h. This really doesnt matter since only YouTube takes HEVC and 6000 kbps Nvenc looks the same as 7000 kbps QSV/AMD and YT has a crazy high bitrate limit of 50 mbps. Even on my computer with a 3900x CPU. This is a real hardware solution that can convert videos quite… Jan 1, 2023 · For example: x265 vs x265(nvenc) or x265 10bit vs x265 10bit (nvenc) Maybe we shouldn't compare encoding time for now. For multiple resolution encoding obviously HW encode save time, but if you're looking to compress 2-3h of video maybe you should use slower cpu encoding (it will alyaws give better results) Jul 22, 2020 · For some time now, a separate encoding chip, which Nvidia NvEnc has christened Nvidia NvEnc, has been used in many NVIDIA graphics cards. Sep 27, 2024 · x265 is a specific software encoder for H. x265 is a software that encodes a video into H. Use CPU encoding for off-line encoding if you don't trust NVENCnew. For the moment I'm trying to brute force my way through like 7000 files. Possibly hold for now until the midrange 40-series come out, as they have dual AV1 encoders that outperform both Intel ARC and AMD's implementations. 5 hours most of the time. especially H265 on ffmpeg cpu preset slow is very nice and small file. H264 - Nvenc is king, QSV is a close second, AMD lags far behind. If you have an older, slower CPU, however, you could use Yes CPU (Software encoding) is still superior to GPU (Hardware encoding) in quality to size ratio. So you'd buy your Zen based CPU, use more power and system resources to encode on the CPU, and still end up with a lower quality stream. The first one is hardware encoding using an Nvidia GPU. If you have an older, slower CPU, however, you could use NVENC on the GPU instead. While AV1 isn't supported on Twitch yet, it'd be g It seems like the major changes are AV1 encoding support, and possibly multiple NVENC chips, allowing for up to 8K encoding, or more concurrent sessions (like to stream and local record at the same time in two different quality settings). But Turing’s NVENC is a very good alternative, especially on weaker CPUs. Keep in mind that cpu and gpu encoding settings have different weight, you can't compare them. I screenshotted the frames and compares them to make sure I wasn’t going crazy. Ended up deleting them all and then using CPU encoding. This ISN'T about getting better performance on my main GPU. You would need a two PC set up and a beefy CPU to beat out NVENC with x264. Now, I am aware hardware encoding isn't as efficient as CPU encoding. So, a non-F 12000 series Intel CPU + RX 6800 would get you top-tier encoding quality while not compromising on performance. Which is how they're usually utilized. It's there for the purpose of live streaming while gaming while having near to zero impact on the gaming performance. 265 format) On developer Oct 15, 2018 · The problem is that if you’re running a game on the same system, CPU encoding is going to hurt performance. Resolve has no options on where to render. Old Nvenc, yes, cpu encoding was better, new rtx and gtx 1660/ti, you need a really really beefy cpu to have a better, more consistant quality. 265). 265 video, it has nothing to do with NVENC. It's because x265 can use more advanced encoding options and reduce the file size. NVENC is absolutely knocking it out of the park on encoding quality. Maxing out the settings for the GPU, 1080 bluray to H265 encoding look almost identical to original source (to my eyes) and take under an 1. Gpu encoding can't do as much while cpu encoding is really good at low bitrates, For good quality gpu encoding you need way too high bitrate. If you want a DNxHR file, that will be Nvenc in my experience is fast and efficient on system processes, but it is very hungry on disk space when set to a CQP of 20 or less. If you use CPU encoding long enough while gaming using the same system, you may notice that although your FPS is fine you will likely encounter frame pacing issues. Replace it it with -c:v h264_nvenc. I use a relatively recent gen GPU (1660) for 1080 or lower encoding. In terms of quality NVENC is far better than VCN (AMD), but performance is going to be nearly identical, and you will get better fps with either than if you're encoding on your CPU. Even if you have a great graphics card to help accelerate these workloads, a strong CPU goes a long way in reducing total render times while keeping the final project looking high quality. The second one is CPU encoding. How does it compare to software encoding with X264 on CPU at 6 Mbps, and which should you use Mar 10, 2023 · Granted, Arc has two video engines, but the UHD 770 only manages 44–48 fps at 4K with H. If you're using CRF rate control on X264 or X265, then sure, X264 is better than NVENC. GPU is much faster, but leaves you with a much bigger file size. Learning that as I get deeper into this. If I do HEVC NVENC 10-bit, I'll get around 25-30 FPS, which is much more reasonable. 04 repositories. For fast H. So let's put encoding time aside and talk about the quality and efficiency (quality/file size) . But the GPU is light-years faster encoding. I hope this helps, and good luck with your streaming! Using NVIDIA 3090 for Encoding: This is a common choice, especially with NVIDIA's NVENC encoder, which is designed to offload the task of video encoding to the GPU. Feb 15, 2019 · This is (hopefully) the last video I make on the subject for a while, but I'm still getting questions about how the "New NVENC" introduced in OBS v23 differs Check EposVox's video: ''AMF vs QSC vs Nvenc vs X264'' so get more details about CPU encoding and AMF/VCE. Oct 15, 2018 · NVENC vs. Nvidia has updated its NVENC video encoder with its RTX cards. GPU encoding is faster than CPU encoding, news at 10. The 8700K is a great gaming CPU. from what I've read, cpu > QSV (which may be > or =) NVENC when it comes to quality, and the opposite for file size, encoding time. not being reprocessed again,) then you should really use CPU Jan 30, 2024 · This means that if a CPU is good for video editing, it’ll most likely be pretty good at video encoding and transcoding, too. HandBrake 1. It's going to struggle to output a high quality 720p60 encode. I've tried upgrading my GPU to an RTX 4060 recently, which had a negligible effect on NVENC encoding speed. NVENC is actually not far off of software, though I would still use software encoding. 1 GPU: GeForce RTX 3090 Encoding Time: ~30 minutes File Size: 18. NVENC is highly efficient and produces excellent quality streams with less CPU usage. Nvenc is going to be way faster on the vast majority of machines. when nvenc with h265 encoding was released, i was impressed how fast it was compared to my cpu. Also known as HEVC. I use CPU for 4K, HDR or the like. the compression efficiency and speed tradeoff compared to cpu encoding. 264 and 265. But Turing NVENC has proven to be much more reliable and higher quality than X264 for streaming (CBR/VBR rate control), especially at less than 10 Mbps. Will be encoding 4k drone footage. Encoding Speed. exe a high priority because otherwise windows will slow it down no matter how many cores are free. You'd be best served with CPU encoding or NVENC. I had to blow an image up to see the difference in quality. Which strongly encourages the use of Intel’s Quick Sync instead of Nvidia’s NVENC. Going to a higher preset for CPU encoding is going to be even more performance impacting than what this test shows. This includes the GTX 1650 rev 2 and higher. NVENC as well as Intel Quicksync are designed more for real time encoding and won't be as bitrate efficient as encoding non-realtime via CPU. I don't think this statement properly expresses the idea that the NVENC hardware H. Currently, an NVEnc-encoded file is nearly double the size of the same file that is encoded via CPU. Check the list of NVIDIA GPUs with NVENC. my main usecase is archiving a mix of presentations and screen content. I found H265 (NVENC) to be 'almost' as good but x264 Medium did better in preserving fine details. X264 — Does CPU or RTX GPU encoding work best for Twitch? Jeff Grubb @jeffgrubb. For best results, use a GPU with 6th generation NVENC (Turing). 265 outperforms x. Majority of fusion only uses CPU. Mar 30, 2022 · Technically, the best streaming setup would use a powerful CPU and a higher quality software encoding preset. nVenc was never made for the purpose of re-encoding. – Change Video Codec to H. edit: actually just realized this other comparison here has a graph that does compare SVT-AV1 to Arc AV1, to give you an idea of the trade-off of AV1 hardware vs AV1 software encoding. You've got an Nvidia graphics card that will be used for encoding if you select NVEnc. Ultimately, the best approach is to experiment with both CPU and GPU encoding to see which produces the best results for your specific setup and needs. It's much more efficient to use both, that being said maybe using just NVENC could be different to this, but I haven't been able to notice any difference in quality. Doing the same with NVENC on a 3080ti on the slowest preset with CQ:30 gets done in under 2 hours (almost), produces a file between 10-25% of the original in size and I think it looks great. The decoding process will still use your CPU. 265 is x265 (CPU encoding) and NVENC HEVC (hardware encoding). Nvidia calls it nvenc, AMD calls it VCE, and intel calls it quick sync. While it's true that NVENC doesn't use any resources that would otherwise be used to run your game (as in CPU, GPU, RAM), OBS itself still obviously uses CPU, and to many people's surprise, actual GPU power that takes away from what your game could otherwise be using. Quicksync of Intel isn't software encoding, it is hardware encoding, and it is not used when you use typical software encoder like X264/X265. I've of course searched this topic before, I know Nvenc works far faster typically but CPU encoding is deemed higher quality and more precise, albeit not that noticeable in most cases. But it only does h. x264 CPU software encoding is accessible for most users. I started encoding my library with a Nvidia Turing card, both bluray and uhd Blu Ray. That being said, regardless of what Nvidia says, NVENC is not as good as x264 (CPU) encoding in terms of quality. HandBrake CPU or GPU Encoding, Which Is Better? "Last year someone asked here if GPU encoding was worth it and was told to stick to CPU encoding. This was true, but newer ffempeg implementations now use CUVID as a way to call NVENC/NVDEC, which is now reflected in the link provided in the documentation link at the bottom: CUVID for encode and decode is decades old and should be considered depreciated. Question: I did some close up comparisons of the videos, and the quality of the x265 file is pretty comparable to what NVENC produced. Encoder: H. 22. H265 is the codec, X265 is your processor’s encoder which can only encode h265. 265 Nvenc/QSV is offers fast encoding Better for Screen recording or Gameplay recording But if you want to compress a video x265 or SVT-HEVC would be better although x265 is Dec 18, 2024 · In simple terms, NVENC encoding relies on your graphics card’s (GPU) computational power, while x264 emphasizes your processor (CPU). 1 FPS vs 1,000 FPS. This option rarely hurts performance. I use h264 Nvenc on Slower (slowest crashes for some reason) and do most feature length movie encodes in 9-13 minutes, whereas if I switch to CPU two-pass it takes between 90 and 110 minutes. I'd say it's worth getting a cheap 10th or 11th gen intel CPU with integrated graphics for this use case. However, I can't help but think it's not using my card (1080 Ti) to its fullest. RADEON AVC = Bad (Horrible if compared to X264 fast, medium & slow, and also if compared to Nvenc new). But the problem in the past was that NVENC’s quality wasn’t comparable to X264 at 6 Mbps or lower. 264 software on slow setting, though it will lag behind software x. Jan 29, 2024 · Q4. It would be great to know if there is a further consideration here to get file-size reduction via NVEnc and/or if I am SOL. u/countercruel Mar 31, 2022 · GA10x GPUs include the seventh generation NVENC encoder unit that was introduced with the Turing architecture. If you choose Intel QSV, the little GPU built into your CPU will be used. And in cases where you want to game and send real time video from the same PC you often choose "less CPU time" as in -cpu-preset=fast or veryfast. If one completes much faster than the other while giving equal results, use the faster method. H. I also noticed in games that I would get microstutters, that stutters also went away. 265 encoding, the VCE and NVENC hardware encoders are considerably faster than the x265 software encoder, at the expense of some quality loss. – Select H. I don’t have the screenshots anymore. Anyway the real underdog here is Intel QuickSync. CPU encoding will probably always be “better” but slower. My ultimate reasoning was I was going to get the best quality and space savings with a cpu. It only relies on raw computing power of your CPU. With TV show DVDs, this probably isn't much of an Well, nope, I was using x264 on 864p @ fast, switched to the new nvenc chip on the rtx cards and have a better stream quality since then. Solution -Enable Hardware Encoding in Software. Feb 3, 2019 · From what I understand, by using your gpu nvenc to encode, the encoding goes through the gpu hence lessening the load on the cpu right? Does that mean I can prioritize a better cpu performance like an i7 stated below. RADEON HEVC = Excellent (Better than X264 fast & medium and also a bit better than NVenc H264. Nothing comes close to CPU encoding. i had to look and it seems the reviewer knew what they were doing. It won't "favor" anything, you decide if you want hw/sw encoding. Hardware encoding relies on specific hardware, the most addressed being NVENC, followed by QuickSync and AMD VCE. You will need a GeForce 750 Ti, 900-series (Maxwell), or higher. 265 as well as resolutions up to 8K are supported. Sep 13, 2018 · GPU vs CPU encoding - Part 1 . The post details some of the issues with NVENC transcoding most notably that, “the encoding process will use your GPU. 265 is superior because even though it is more computationally complex, it can compress better. Your point is undermined by the fact you're using x265 settings that are unfavorable to the metrics (time, VMAF) and constraints (size) you're using for comparison; all you've demonstrated so far is that if you configure x265 poorly for your goals, you can get undesirable results. 265 is the encoder. The only issue that I am experiencing is file size. Nvenc new = Good (H. nvenc av1 and qsv av1 have very similar vmaf scores at various bitrates on best presets. – Open HandBrake. Note: GTX 1650 rev 1 contains 5th generation NVENC. And in these cases the GPU encoding on modern hardware can be better. Would sell the GPU and go for a 3080. You're much more likely to see the difference while encoding a 4k movie. nVidia NVENC is a software that uses the hardware inside your GPU to encode into H. What are you trying to achieve with the encoding exactly? Because 370mb seems already quite small. Stop confusing terms. This is the state of. It's best used as a way to offload CPU usage during streaming and it can't be matched in this regard but I can't take NVenc seriously as a movie archival tool, NVEnc Av1 is marginally better than the outgoing HVEC before it. 264 the GPU overload went away. This is a real hardware solution that can convert videos quite… CPU Transcoding for H. Regardless of hardware or software encoding, a computer is still analyzing the same source in each case. bwig hmn nwmvk jrly ufubig jeokbgc vnigmmn vsoi xiq qqjdvf nfam mbvyk wlwhrayl hbxd vkz
