![]() The encoders are within a 2 to 3 VMAF points of each other and I think the general rule of thumb is that 6 VMAF points of difference will result in a noticeable difference in video quality to most viewers, while differences smaller than that can be difficult for many people to spot. There is a comparison here between Quick Sync (Skylake version), NVENC (Maxwell version), and x264 Medium (software encoding):Īll 3 are close enough in terms of quality, such that if you are comfortable using x264 Medium, you should be fine using either of the hardware encoders as well. Maximum processing parallelism (from 0 to INTMAX) (default 4) -avbraccuracy E.V. I think the general consensus on recent versions of Quick Sync is that H.264 encoding quality is pretty good, but slightly behind NVidia's NVENC encoding. Encoder h264qsv H.264 / AVC / MPEG-4 AVC / MPEG-4 part 10 (Intel Quick Sync Video acceleration): General capabilities: delay Threading capabilities: none Supported pixel formats: nv12 p010le qsv h264qsv encoder AVOptions: -asyncdepth E.V.![]() I think any improvements in H.264 quality were probably not as significant though or Intel would be touting them as they do the HEVC improvements: Ice Lake (10th Generation) did bring about Quick Sync improvements including gains in encoding speed and HEVC encoding quality. Kaby Lake (7th Generation), Coffee Lake, and Comet Lake processors all share the same Quick Sync implementation so I'd expect encoding quality to be more or less the same across all of these processor versions. OBS Studio has lots of tools and features to produce high-quality live streams.There were some significant improvements between the initial version of QuickSync H.264 encoding in 2nd Generation (Sandy Bridge) Intel Core processors up through 5th Generation (Broadwell) and 6th Generation (Skylake).Ä«ut I think most of the attention in more recent versions of QuickSync has gone towards the HEVC and VP9 encoding features, so any improvements in H.264 encoding quality have been fairly small in these more recent processor architectures. Quite reasonably, this comes with a whole bunch of settings that have to be optimized for the smoothest performance. Although streaming platforms have different optimal settings for top-notch broadcasts, there are some general recommendations suitable for live streaming on every platform. Letâs go through the key points of attention. The best OBS settings for streamingĪrguably the most important for any streamer is the upload speed. This parameter allows you to continuously send your video content over to streaming platforms. The more upload speed you have, the smoother your live streams will be. However, the general recommendation for the upload speed is around 5 Mbps. August 2022) Open Broadcaster Software (OBS) ist eine freie Software, um den Bildschirminhalt eines PCs aufzuzeichnen oder über das Internet zu übertragen ( Live-Streaming ). Intel Quick Sync - OBS Quality Comparison st0rmpc 231 subscribers Subscribe 195 Share 37K views 5 years ago Settings are all shown in the video. ![]() If you want pixel-perfect live streams, change the Video Bitrate to 4000 Kbps.Open your OBS Studio and click Settings on the bottom-right of your screen.With that being said, letâs look at the main settings you need to adjust in OBS: You can learn more about the best upload speed for live streaming in our blog. ![]() ago It seems that these other recording ways have worse quality, this is based on what I have seen recorded with them. This is the optimal video bitrate for live streaming in Full HD (1080p) at 30 FPS. CPU encoding has always been quite heavy, but if you use NVenc (the NVidia on board hardware encoder, same as used by shadowplay) or quicksync (uses iGPU) you get hardly any performance impact. The next step is to increase the Audio Bitrate value to 320 Kbps. OBS Studio reports an error when attempting to record or stream with QuickSync selected as the encoder Sometimes the issue is resolved after a system restart. Our goal here is to download the application and prepare our work environment before we record any content. OBS MultiPlatform is a complete rewrite of the original OBS from the ground up, with the main goals of course being multiplatform support, a more thorough feature set, and a much more powerful API. OBS is a free download and it has clients for Windows macOS and Linux. Audio quality is essential for any kind of live streams, so changing the bitrate to the highest will provide the best sound for your audiences. A very early and simple release is currently available for Mac. Another important parameter we recommend you adjust is the Keyframe Interval.However, if you have a non-music stream, 160 Kbps is recommended for most of the platforms.
