There are supposed to be some good capture devices .
The ones I've read about are Hauppauge but I think any you found would be used.
What I do is I have a good VHS player/recorder (wish it was a SVHS but the one of those I had began to fail some years ago & I junked it.)
I go from my VHS player via SVHS cable for the video & standard red/white stereo cable for audio . This is input to a good standalone DVD player/recorder.
This has to be done in real time but so does VHS to a computer .
For commercial VHS movies:
You will need a video stabilizer like the Grex Dimax (the one I have).
Or one of the other good quality ones. There are some of those recommended in threads in this forum.
This is an example :
This video was done as above .Written to a DVD +RW.
The DVD +RW was ripped to my harddrive with CloneDVD2 .
I then used DVDShrink to cut out the clip.
Converted the clip to a .mpg with VOB2MPG v3 .
I uploaded that to YouTube & they did whatever conversion they do.
I posted it here at club.myce in this thread if you want to take a look at it.
Considering all the conversion I think it looks pretty good.
Try watching it full screen.
