[FFmpeg-user] ffprobe -show_frames values

[Joel Lopez]

Could I just run my unaligned files through ffmpeg again with a set
keyframe interval and disabled scene cut detection?

Or do I need to scrap them and re-encode the source file and generate
new files that are properly aligned?  We have thousands and am trying
to save time where possible.
