This is a research question.
I want to make a video which will be "invisble to kids" but
"visible to adults".
Theory says this is possible because the PFF
(picture fusion frequency) of adults is around 15 frames/sec,
while the PFF of a 7 year old kid is only 10 frames/sec.
OK, I can't use AVI, or MPEG or any kind of
"computer video" system because they are too slow
and tend to compress frame/rates unpreditably....
I have to use good old fashioned VHS tape and
play it on a VCR.
QUESTION:
How can I most simply EDIT a VHS tape?
What I want to do is take "any ole" average VHS
movie tape, and simply REPLACE some frames on
it, and then play it on my VCR.
How can I most EASILY do this?
Specifically, if I have a regular VHS video movie,
I wish REPLACE every 3rd,4th,5th,6th
frame of the video with "blank" frames
(say colored light gray)... so the tape will
look like this:
01|02|...|...|...|...|07|08|...|...|...|...|13|14|...|...|...|...|19|20|...|..|...|...|25|26|...|...|...|...|-------etc,etc,etc------>
the |...| frames have been REPLACED in the original video
with these new "blank" (light gray) frames.
HOW CAN I DO THIS.... what type of equipment, computers, VCR's
etc do I need to do this?
Could a run of the mill commercial video lab alter a VHS tape
for me in this specific way?
Thanks in advance, Ted
