reframekit
Make the versions of a finished video that each place takes, such as a launch film, a product demo, a screen recording or a clip from a video model going to TikTok, Reels, Shorts, the feeds, YouTube, X or LinkedIn. Writes 9:16, 4:5, 1:1 and 16:9 files with a crop that follows what moves in each shot (or the whole picture on a blurred copy where a crop would cut too much), each cut at a shot change to the place's length, kept under its file size limit and set to -14 LUFS, with a cover, crop.json and sheet.png to check and move the windows, and a check of any file against a place's limits. Use it whenever a video has to go somewhere in another shape or within a place's limits.
