I'm tweaking my video workflow. I use Orgzly Revived on my Android phone to write the text, and I use Easy Voice Recorder to record it. Syncthing automatically copies both to my laptop. I use WhisperX to transcribe my recording, and I use a little bit of Emacs Lisp to figure out timestamps for each word. I edit this to fix errors. I can even rearrange things and get rid of umms or ahs or anything I don't want.Then I use subed-convert to turn it into a VTT file. I can tweak the start and end times by looking at the waveforms. Then I add comments with the visuals I want. I can add images, animated GIFs, or videos, and they're automatically squeezed or stretched to fit. I can also have them play at original speed. Then I set up open captions and use subed-record-compile-video. Tada!
