I want to continue the topic Old post
related to creating TBC with Arduino.
My idea is to connect arduino to VCR and read the RPMs of the tape to later draw it out and do post-processing of the ripped file with VirtualDup and adjust the framerate according to tape speed during ripping process(that was done pre)
What do you think about that idea?
I was also thinking of Reading the message reported by VCR "A.TRACKING" and using it as indicator of drift(but not sure if that can be usefull).
I think as time goes on, and analog video tapes continue to age, it's more important than ever to transfer & archive them to digital. Making TBC available and affordable to regular people to help them do a higher quality transfer is a worthy cause, and should be possible with today's microcontrollers & single board computers like Arduino and Pi.
That said, I'm not an electronics or a video expert (just a hobbyist with some programming experience) so I'm little more than an idea man & cheerleader in this area. But from what I've seen & read over the years, I do think this should be possible and is a good idea with practical value. To make it happen, we'll need more technical people than me, who have the attitude "where there's a will there's a way!"
I'm good with programming and stuff, arduino and video scripting(creating scripts to postprocess videos). With analog electronics, i'm a newbie. I'd need help from someone who could help me understand the analog head of a VCR and how to recognize a pin to read the tape speed, then how to connect to an arduino analog input for read. Logging it would allow me later to script video post processing(PC software) of a video file done by a cheap grabber that recorded at fixed 25fps
