i realize there may be other more eficient means with the advent
of cheap digital capture but this was more of a hobby project for
fun and **Learning** exercise as VCRs are very cheap and easy to
come by
so the idea is to get a standard issue VCR and modify to become a
time lapse recorder say something like 5 fps , 1 fps or 1
frame every 5 seconds
how much can a standad VCR be slowed before significant
degradation in image quality ?
is this mod possible ? what sort of changes to make ?
my own thoughts from my limited VCR undersranding are these
issues :
1. This mod makes no sense if the tape record capacity can not be
increased so tape movement needs to be changed
1a. slowed down easier i suspect but image quality threshold
is problem
1b. stop and go to *BUT* more complex with timing and
gettting tape up to speed from full stop and the mechanical plus
electrical problem with the go part
1c. slow down speed up combo to eliminate the issues with
complete stop and go
2. Recording Head speed and timing with the tape movement ?
3. Playback issues. can such a tpe be played in any VCR or just
the time lapse
4. Just use a Different technology like some digital storage
capture and take a pics at desired frame rate
