Video software frame by frame play

I recorded videos where I test input lag of different setups. Do you have recommendations about what software to use to play videos (frame by frame) so that one can calculate frames to estimate how much input lag there is?

At least VLC, totem or Openshot don’t seem to support this. Or maybe they do I just don’t know howto enable such playback mode.

Try Blender, it has some real nice video tools.

The default binding for the e key in VLC is Next frame. I use ffmpeg to add time stamps and frame counts to the bottom to keep more precise track of location.

Thanks this was just what was needed.

FYI if you (or anyone else) uses mpv: . is frame forward, , is frame backward.

Oh and in case someone who stumbles here later. Here is pointers for ffmpeg command.

ffmpeg -y -i input.MOV -vf "drawtext=text='%{pts\:hms}':x=(w-tw)/2:y=h-(2*lh):fontsize=36:fontcolor=white:box=1:boxcolor=0x00000000@1" ffmpeg-timestamp-counter.mp4
