dropped frames at 23.976 but not at 29.97 with Huffy in VD

[macjohn]

I've been capturing NTSC Huffy 29.97 in virutaldub without any frame dropping. When trying to squeeze 45 minutes onto an SVCD, I have had too much blocking no matter what I do to improve it on the conversion. So I decided to go back and capture in 23.976 frames per second. First, Virtualdub is dropping frames left and right and reporting only about 19.9 frames per second being captured... second, that AVI is obviously jerky and worthless.

Any advice on how to capture 23.976? Or is that just not possible? I'm at 480 x 480, should I be at a different size if I want SVCD film?

the answer to your question is no, so I have been told. I am assuming that you have an NTSC card (since you said you have been using 29.97 fps)...I am not sure why, but some of the experts here could probably give you a technical explanation (actually, I would like to hear it )

My suggestion is to go ahead and capture at 29.97 and use AVISynth or TMPEG to IVTC the video. I use AVISynth and the Decomb package to IVTC ALL of my captures from a film source and they look great and I save space...

did you have any problems with jerkyness when you converted with TMPGenc? I tried that and scenes that panned were very jerky. I guess I'll try that again with some different settings. Thanks.

I never even tried to do it in TMPEG...AVISynth is the way to go...amazingly powerful and easy...you can probably do it with VDub too, I have just never tried...
