I have just had a look at the solution via subtitles: Pro: * It works and the SRT format is simple enough to be written by a script. Cons: * SRT subtitles are written time-based and not frame-based, which takes some calculations, starting the subtitles shortly before the frame and ending it within the frame. * This does not seem to work at the start of the video (frames 1, 2). * I seem to have no influence on where the subtitle is placed. It appears at the middle of the bottom. ... The drawtext filter has an option to read text from a file, but I guess this cannot easily be used to read lines on a per-frame basis (?). Wolfgang Hugemann
