Well, I am not saying it isn't possible to have hidden tracks under the video, but it sounds like something James Bond or the CIA might discover. Or some CSI show where they sharpen a photo to turn 16 pixels into a sharp photograph of a face.
You see what you see. Every time.
If some other video shows up, I suggest calling the people from one of those Ghost Hunter shows.
Now, seriously, how are you playing the video? If it is from tape based media - analog media - then you need to buy better tapes. Or stop erasing them and reusing. Buy new ones.
I'll try again. My bad for being too brief. Answering questions is not a problem.
Its not like a prestine video content suddenly appears. The main content becomes visually corrupt or fragmented, pixilated, smeared, etc and alternate content becomes visible for brief periods.
I'm viewing video files with vlc and premiere pro, but not skilled enough to devise a procedure to expose the underlying content.
I have seen this happen on occasion over the years when reusing MiniDV tapes - during a glitch or "dropout", the original recording may be shown momentarily. Perhaps this is the issue? We don't know what media you are working with

Dude, that kind of thing is in the video itself. Nothing you can do but reshoot.
