Notes (from the sources, in English): Since June 2025 all Facebook videos (except stories and live) are shared as reels and can be any length or orientation, so no max duration is given. Requirements page: MP4 recommended, 1080p, H.264/H.265 (VP9, AV1 supported), 24 to 60 fps, AAC stereo 128 kbps+. 1080x1920 / 540x960 minimum and 3 s minimum come from the Reels Publishing API, which still limits API reels to 3 to 90 s. Caption limit 63,206 is an industry figure.
In 9:16 the app covers parts of the top and bottom of your video. Check your frame with the safe zone checker or download the safe zone templates as PNG.
Work out bitrate and file size with the file size calculator. Check caption length with the character counter.
