each frame / JPEG. (As you can tell from my name, I am not a native
My question is however where exactly ffmpeg's timecode stems from. It
doesn't seem to be a simple frame count (?).
The Exif timestamp's accuracy is only integer seconds. A more accurate
timestamp could only be written into the JPEG comment or into the XP
comment Exif tag, I guess. By default ffmpeg writes the name of the
codec library (Lavc57.38.100 in my case) into the JPEG comment. I have
no idea whether you can change this behaviour.
