Before uploading, settle where the video is going and in what shape: a standard YouTube video, a Short, or a vertical clip for Reels or TikTok. The export settings and vertical format guides cover how to deliver each without re-editing from scratch.
Check rights next. Read the music and stock footage licensing guides, and the commercial-use guide if the video is for a client, before you publish, since claims and takedowns are harder to fix afterwards than a swapped track.
Finish with the packaging guides: custom thumbnails, chapters and intros. If your file is too large to share or upload comfortably, the file size guide explains how to shrink it while keeping on-screen text readable.
