The AV1 default is the maximum compression I can use uniformly. Navigation Menu Toggle navigation. Yes, I am well aware hardware encode is inferior to software encode in terms of quality but I'm mostly just playing around with it. Video Encoder: AV1 10-bit (NVEnc) b. 1% loss for libaom, this one correlated with big speed gain, with a single clip taking from 38 I don't notice a difference from 19 and below (with enabled film-grain synthesis though, could vary). To quantify the quality improvements, we investigated peak signal-to-noise ratio (PSNR) and video multimethod assessment fusion (VMAF) scores for AV1 and H. Topaz labs is a paid program but is well worth it compare to Handbrake. If you're building a new setup and don't need AV1 (eg, Twitch streamers since they're still stuck on h. ly/b54F9Windows 10 Home ($14): https://biitt. what I'd like to know is the delta. The shot features a house from Fortnite, and while its I've been comparing Nvenc, x265, x264, and AV1 SVT while waiting for my Arc. Conclusion about H. Whichever faster CPU is better, so in this case, any Ryzen would be a better option than Intel. g. This is a tool I made and don't have a 4xxx card to test with so please let me know of any issues! When rendering videos, I have the option of using Nvenc (Nvidia GPU) or my CPU to do the heavy lifting. Help Which is better for getting sharper and better quality recordings with CBR? Using RTX 4090. Then save it. If AV1 requires more source-specific tuning (ie, newer film vs grainy older film vs B&W vs cartoon vs action with lots of motion vs non-action film without a great deal of high-motion) then I'm not sure that re-encoding my library will be worth it. Now of course some images can't say everything but I recorded multiple minutes of gameplay and at 16000 kb/s and anything higher AV1 is just getting worse and worse compared to the other 2. Skip to content. You signed out in another tab or window. Tl;dw SVT-AV1 preset 7 or 8 (afaik with the old version of SVT-AV1 that OBS currently ships) >>>>> Intel AV1 ~= x264 very slow >> Intel Quicksync > Nvenc >> AMF 3. 265) is better at compression than H. Comparing av1_nvenc with an SVT-AV1 at preset 3-5 at watchable quality (cq 32 against crf 28) size difference is between 25%-40% in my experience, and the quality is less consistent. Still it's very good compared to nvenc 264 and 265 Dec 23, 2020 · Did a test of the NVENC GPU testing rendering options, but what are the differences between them? SUPPORT I did some testing by rendering a 6 hour 720p 30fps video and using all the gpu testing options and the regular . AV1 should be about 30% more efficient than H. It seems the 8th gen Nvenc is much better than previous versions and Nvenc AV1 can produce a similar result to SVT-AV1 preset 7/8 at the same bitrate (based on VMAF). But I might be able to sort the files by bitrate and use less compression for lower bitrate input videos AV1-45 works well for most videos and is a bit smaller than the HEVC-28, while being a bit higher quality. Don't be afraid to experiment with such values with SVT-AV1 and AOM-AV1, H265 NVENC vs. 264 if the video quality is That being said. Contribute to Alkl58/NotEnoughAV1Encodes development by creating an account on GitHub. You signed in with another tab or window. Run obs as admin and disable gpu hardware scheduling in windows as I found this causes obs to use more of the gpu chip and not just the nvencoder, quite a bit more e. Personally, I use HVEC because I'm only running a 3080. Intel has it's quick sync, NVIDIA the NVENC and AMD the VCE/VCN. Refer to the NVENC Video Encoder API Programming Guide for more details on this feature. NVEnc-AV1 is 8 (eight) times faster than SVT-AV1 (see below). ) As for ordinary consumer, that could be a strong signal for more tech giants get in & with their efforts to push At 6 and 8mbps, Intel Arc’s AV1 encoder goes back and forth between scoring higher than X264 VerySlow and scoring slightly lower (VMAF scores operate on a 0-100 scale with 100 being a perfect Nvenc AV1 (RTX 4090) Nvenc AV1 (RTX 4090, 10 bit) QSV AV1 (Arc A770) QSV AV1 (Arc A770, 10 bit) The encoders tested for the Minecraft clip were the following: x265 (medium preset, 10 bit) SVT-AV1 (preset 4, 10 bit) SVT-AV1 (preset 6, 10 bit) SVT-AV1 (preset 8, 10 bit) 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). 2% percent improvement for libvpx and 0. The big advantage here is moreso that you are comparing a hardware encoder to a software encode and getting equal results. NVIDIA NVENC H. So lately I'm messing around with Shutter Encoder, and saw it has the AV1 output support. As such, I have to ask, just how prevalent is Nvenc encoding? Key: -Not applicable to this API. 264, but still needs more hardware support for the encoding side of things. Since the NLE friendly DNxHR is too huge to store, Using libsvtav1, what QP value is considered 'visually lossless' or roughly equivalent to Nvenc H264's CQP18, or x264 CRF14? H265 vs AV1 Hi Everyone, I recently did a deep dive comparing H265 and AV1 on actual data and running a lot of experiments in Python. Quality: Try 40 (larger number = smaller file size; too large can lower quality) e. The same system was used for both runs, Ryzen 9 5900X, 64GB RAM, RTX4090, latest nvidia drivers as of yesterday 2/9/24, latest Handbrake as AV1, or at least SVTAV1, shines very well when you are really cramping down on the file size. ⭐ Watch this video ad-free on Nebula: https://nebula. 😁 Remember to leave like and subscribe channel! 😁⚠ Notice ⚠The data shown in the video are demonstrative. 264 if the file size is the same. I was planning to buy a new GPU mostly for AV1 encoding, but I guess I'll stick with iGPU QuickSync-powered HEVC. Jan 25, 2019 · This means QP 23 video of NVENC h265 would be the same filesize as QP 23 NVENC 264. AV1 I think enabled new codec on YouTube or so I've been told. The video quality of AV1/HEVC will be better than H. The For anything CPU vs CPU, there won't be any difference if you are using AMD or Intel. There are some sub profiles on some standards which may or may not have support, but in NVENC seems to pull ahead when the source has a high bitrate in these tests but is dead even with VCN when the bitrate is dropped to 15Mb/s. X265 CPU - Whats the current state of play? Apr 8, 2024 · Comparing av1_nvenc with an SVT-AV1 at preset 3-5 at watchable quality (cq 32 against crf 28) size difference is between 25%-40% in my experience, and the quality is less consistent. A PSNR of 45dB is achieved around QP=48 and 40dB at QP=120. I just have a basic HEVC transcode setup going. mp4 Nvenc VS Intel QSV? Any benefits to Nvenc or QSV when using handbrake to compress my movie/tv collection? It's a mix of 1080, 4K, and 4K HDR titles. AV1 will by far take the longest, but it will give you a much smaller file size. Example: I run Outplayed (screen/game recording application) uses NVENC and Discord uses NVENC when I squad up to watch friends streams. Full disclosure: I've got older hardware and no current hw encoders on my gpu (well, an outdated quicksync and nvenc which are a lot worse than x264). There's some guides on tuning NVENC for h265 but it seems like they don't exist for AV1 quite yet so I looked through ⬇️All technical details will be down here⬇️This video was uploaded in 8K to force YouTube to use AV1 on their end. 85% vs 46% cpu usage on X265, roughly same encoding time. The chart also shows that you can chose AV1 and still gain quality even on the fast settings if you're willing to spend the time. I As for you question AV1 > HEVC > x264. You can read more about it here. Thank you very much! I have Oct 14, 2022 · There is no AV1 hardware preset for NVEnc. AV1 is another jump that is very worth it in my opinion. . AOM AV1, developed by the Alliance for Open Media, focuses on providing a royalty-free and open-source solution for video encoding. Quality wise it will be the same. However, I don't find it very well-tuned for the use cases where every detail needs to be retained (low CRF levels around 20 and To quickly recap, the AV1 encoder built into Intel's new Arc discrete GPUs outperformed both Nvidia's NVENC encoder and AMD AMF by a whopping 16% in real-time gaming tests. On my AMD 1920x with NVidia RTX4070, I exported a video with 600 frames in 5760x2880 (VR) in three different formats: SVT-AV1 (CPU based encoder), NVEnc-AV1 (GPU based encoder) and NVEnc-HEVC . IMHO, the GPU-based encoders are only good for the thing they were specifically designed for e. 0 on Ada GPUs for HEVC and AV1. Comparing compression quality on QHD 1440p 60fps Overwatch gameplay using Neflix's VMAF. One does not have to do any pixel-peeping to notice. So equal size but Arc AV1 was every so slightly better quality (VMAF 74 vs 72), but really those VMAF scores are going to have no perceptible difference when viewing. For a given bitrate there is some quality loss with hardware vs software encoders (numerous quantitative tests on the official Vegas forum) but it may not make a difference for your intended purpose. 265 or av1 is for. The new AV1 encoder can now give a 40% increase in efficiency with improved resolutions and quality, according to testing conducted by Nvidia. May 3, 2023 · In context: It's no secret Nvidia's NVENC media engine in GeForce GPUs has been the preferred option for streamers for years, but AMD and Intel have recently done a decent job of catching up. 264 and HEVC: B-frame: support for non-reference, reference and hierarchical B frames. New comments cannot be posted and votes cannot be cast. Some FPS games struggle with also streaming with NVENC, so I’ll use X264. This means that NVIDIA NVENC is approximately 11 times Nvenc will give you the fastest results at the fattest size per visual quality. Nvenc AV1 is better. 264 and h. But x264 also puts a much bigger load on your system than Nvenc H264. 265, and AV1 encoding capabilities in speed, file size, and quality. Please contact the moderators of this subreddit if you have any questions or concerns. 265 and lower those bitrates to that amount - once one has found the equivalent Hello, AV1 is generally more efficient than HEVC encoding, but for high quality output with less priority on file size reduction I would recommend trying -c:v av1_nvenc -preset p7 -tune hq -cq:v 20 -rc-lookahead 48-rc-lookahead can be adjusted based on the framerate of the input file, but usually it’s recommended to set this to double the framerate. Considering that NVENC offers a better stream quality for games than x264 medium, the hardware solution is clearly preferable. NVIDIA NVENC AV1 vs. AV1 will be the future standard in video playback. On Ada, multiple NVENC coupled with AV1 enables encoding 8k video at 60fps alongside a higher number of concurrent sessions. SVT AV1 What's the Difference? AV1 and SVT AV1 are both video codecs developed by the Alliance for Open Media, but they have some key differences. Both codes are pretty efficient and will treat every source different, so comparing results is hard. AV1 and H. thoughts of quality? What is better for AV1 encoding I have not seen any information regarding a direct fight between the 2 in a apples to apples comparison. So yeah - I'd personally recommend considering an Intel Arc card for the streaming PC.
