For YouTube, select Hardware (NVENC, AV1) if you have an RTX 40 Series GPU, or Hardware (NVENC, HEVC) otherwise.For Twitch, select Hardware (NVENC, H.264).Encoder: Here we will select what hardware will be used to encode, and with what codec.

Bitrate: Enter the Bitrate appropriate for your Upload Speed, as we discussed in the first section.

If you want an easy, out of the box configuration, then do the following: You may want to consider streaming at a lower bitrate and resolution to lower the bandwidth required to see your channel. 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. Important Note for High Motion Content.
