This is important if your viewers are on mobile phones or their internet speed is not as fast. Twitch only offers guaranteed transcoding to Partners non-partners may receive transcoding depending on server load. Transcoding allows a viewer to view your video on a different resolution, thus requiring a lower bandwidth. Note for New and Upcoming Streamers to Twitch. For example, for Fortnite, many streamers decide to stream at 1280x720 60 FPS at 6,000 Kbps, down from 1920x1080. If you reduce the resolution, you reduce the data being encoded, and the resulting viewer quality is better.

High motion content cannot be compressed as much, and can suffer from more artifacting (encoding errors) that make your stream look “blocky”. Racing games, FPS games, etc.) we highly recommend reducing your resolution. If you are going to stream high motion scenes (i.e. Most streaming sites have recommendations ( Twitch, Youtube, Facebook) on what to use. Then, we will determine the resolution and FPS that we can use for such bitrate. We want to use around 75% of your upload speed, as the game and other programs such as Discord will also fight for bandwidth. YouTube: H.264, HEVC (beta), AV1 (beta)įirst, run a speed test to determine your upload speed (e.g.RTX 40 Series: H.264, HEVC, AV1 and AI powered effectsĬapabilities per platfomr (as of May 2023):.RTX 20 & 30 Series: H.264 and HEVC, and AI powered effects.Relative Compression efficiency of codecs with NVENC: Video encoded with a more efficient codec will be higher quality than a less efficient codec at with the same file size or streaming bandwidth.Video encoded at same quality with a more efficient codec will occupy less disk space or less streaming bandwidth than a less efficient codec.The benefit of a more efficient codec can be thought of in one of two ways: Newer generations of RTX GPU include support for newer, more efficient codecs. GeForce RTX GPUs have dedicated hardware encoders (NVENC), letting you capture and stream content without impacting GPU or CPU performance. While the same applies for framerate, a viewer can really notice a drop in FPS but not so much in resolution, so we will always try to stream at 60 FPS. The smaller the size of the image, the less we must compress it and the more quality it keeps. Note: we have simplified some of the concepts to make this guide accessible to a wider audience.Įncoding is all about compressing images. The objective of this guide is to help you understand how to use the NVIDIA encoder, NVENC, in OBS.
