Bitrate

The bitrate for YouTube, a live stream, a master…

What it does

The video bitrate to aim for, depending on where your video goes, with the audio, the codec and the keyframes.

Upload (YouTube, Vimeo, Instagram, TikTok): the file size for the length you type, and how long it takes to send with your upload speed.
Live (YouTube Live, Twitch): whether your connection can carry it. Keep the bitrate under about three quarters of your upload speed.
H.264 · H.265 · AV1: a bitrate for your own export, by codec and quality level (a rough guide: grain and fast motion need more).
Master ProRes: the rates of Apple’s ProRes white paper, for the frame rate you choose.
Instagram and TikTok publish no figure and recompress everything: the values shown are a habit (send a clean file), not a rule.
Platforms change their recommendations from time to time: when in doubt, check their help page.
