I have AMD hardware (CPU + GPU). I tried rendering in CinGG a project in h264_vaapi/mp4. Then from external terminal I used ffmpeg to convert the file to h264/mkv. The conversion went well and the resulting file is viewable in mpv. > unfortunately cin on termux segfaults with this opt file: > mp4 libx264 | h264_metadata=crop_left=20:crop_right=20 > # use framerate for 1 keyframe/sec, needed for seeks > keyint_min=25 > x264-params keyint=25 I tried the opt file you suggested and it works fine. I attach the preset. From earlier I had tried the copy/paste from your email, but the line: mp4 libx264 | h264_metadata=crop_left=20:crop_right=20 leads to a dump; instead by going to new line: mp4 libx264 h264_metadata=crop_left=20:crop_right=20 it works well.
