I don't like doubting people's goals, BUT:
A single frame wouldn't be very visible, would it? Since you would need
to use some form of concatenation (that's the key word to search for),
you would need to reencode the whole video just for the sake of the one
Perhaps adding metadata or subtitles would be a better alternative for
you? Both can be added without reencoding the video.
