Video Splitter is available for macOS (Intel & ARM). It uses FFmpeg CI to export extracts (call them "best moments", "shorts" or "clips" if you prefer) from a video.
The binary can be downloaded from https://olfsoftware.lemonsqueezy.com/buy/93892f55-716c-4be3-8e1b-55adc11989db
You can buy a license from https://olfsoftware.lemonsqueezy.com/buy/7e30c358-7759-4801-95fa-6bfd760c7c90 if you want to support this program and my work.
Known bugs : the arrows to move by 1 frame or 1 seconde work but the position is not the good one depending on the video source (probably a player problem with refresh frames in mpeg format)
