Overlaying transparent over the subtitles was a smart idea. Hum. I realize you probably do not need to overlay anything: the trick is to get the subtitles into a filter chain, so that ffmpeg converts it to video: the showinfo filter should be enough to force the conversion. Also, do not forget -vsync vfr, otherwise the image2 muxer will be duplicating the frames. > Le dim. 21 juil. 2024 à 13:57, Nicolas George <geo...@nsup.org> a écrit : Please remember that top-posting is forbidden on this list; if you do not know what it means look it up.
