The first release of Clipper is now available. It works on 64-bit Windows systems running a recent version of Aegisub (not the version available from the official site).
Installation instructions and user guide available here: https://lyger.github.io/scripts/guides/clipper.html
Clipper is an Aegsiub automation that allows you to quickly and easily create subtitled video clips from longer videos without ever leaving Aegisub. Encoding is done all in one step: there's no need to encode once to create the clip and a second time to add the subtitles.
I originally wrote Clipper to help me make translated highlights from long VTuber live streams. lae then rewrote it so that it works on Linux and only depends on FFmpeg. I then re-rewrote it to work on Windows and be more user-friendly.
The release includes FFmpeg and FFprobe 64-bit Windows binaries.
