You are probably correct that MP4 is a more compatible distribution format, but distribution format does not necessarily have to be identical with recording and editing format. I would not anticipate any issue with ...


Try with the movie filter instead ffmpeg -loop 1 -i image.jpg -filter_complex \ ",setpts=N/(FRAME_RATE*TB)[1v]; \ [0:v][1v]overlay=x=main_w*0.44:y=main_h*0.33[out]" \ -map [out] -t 00:00:15 out.mp4


If I've understood you correctly, your video appears upright when viewed in portrait orientation and rotated in landscape.

If so, there are two things you can try using ffmpeg, a free command line tool. ffmpeg -i input.mp4 -c copy -metadata:s:v rotate=90 output.mp4 If ...
