[FFmpeg-user] Converting text to video for dictation

[andrei ka]

guess you should first check a bunch of subtitling programs. from you
description, you're simply doing subtiting of your vids. text placement is
easier done by specialised subtitlers,
and once you're done, you can burn 'em with ffmpeg (the only reasonable
usage of ffmpeg i can image for what you're doing, the rest of it is not
really ffmpeg's specialisation)..
if you're new to free subtitlers google aegisub & likes
