NTSC vs NTSC film?

[ridgexyz]

I have two VHS tapes that I would like to convert to VCD...

1) A collection of music videos
2) my wedding video (awwww)

I have been reading about the different FPS's of NTSC and NTSC Film. How do I know which one of these my VHS tapes are? Is this something that can only be discovered by trial and error? Any help would be appreciated. Thanks!

You Video on VHS should be 29.97 fps NTSC.

Flim rate NTSC video are normally from ripped DVD,
which was processed as flim, and converted
to either flim rate PAL or NTSC.

So if I bought a VHS movie, that would still be in NTSC 29.97 fps?

Yes all ntsc vhs tapes are in 29.97fps. You could possibly do an inverse telecine after you capture your video but that depends on how it was originally filmed. Its worth a try, the results will be much better. You can use TMPGenc to do an inverse telecine.

ridgexyz,

Both your VHS tapes and your wedding videos will be 29.97, however, you might be able to do an inverse telecine of your VHS tapes and encode them as NTSC FILM. This will give you about a 20% increase in quality, but your source video has to be telecined. A basic test to determine if your video source is telecined is to find a scrolling scene (I find these are best for testing) in your captured video and scroll through the frames and see if you find a pattern of 3 progressive frames and then 2 interlaced frames. If so, then your video is most likely telecined and can be inverse telecined. For more info on telecine and inverse telcine, check out http://www.geocities.com/lukesvideo

If you do decide to IVTC your video, I would recommend using the Decomb filter for AviSynth. I personally believe it is the best IVTC filter out there. You can find it at http://www.doom9.org

Also, your wedding videos will not be telecined.
