NTSC VCDs

[spyder]

What method do you use to make an NTSC VCD from an NTSC DVD. I have been encoding them at 23.976fps(using force-film from dvd2avi) but my player doesn't like them too much. It skips very often in the video and the audio becomes asynch. I want to make a 29.97fps one to try but I can't get the interlacing to work right. I tried 3:2 pulldown in TMPGEnc but it created lines that were definitely visible on the TV and then i tried just resizing the output of dvd2avi without force film but I get ghosting. What settings do you use in TMPGEnc to make this work properly? I must be missing something somewhere. The guides here don't give much info on NTSC VCD creation. They're mostly for SVCDs which my player won't handle.

I don't think that the video is skippy because of your DVD player, but because of using Forced Film on a non film source.
Don't check Forced Film in DVD2AVI and check "Inverse Telecine" in TMPG to get real 23,976fps.

You should encode 1 minute or something to see if everything is right. Only then encode the whole DVD to VCD!

If you get skippy playback with Inverse Telecine, that means you have real 29,97fps, so you don't even need to deinterlace or something, reducing the vertical resolution from 480 to 240 will automatically deinterlace your video!
If it doesn't, use one of the deinterlacing options of TMPG

They are Film but they have the RFF flags or whatever that make them have 3:2 pulldown on playback. That's why I used forced film. It ignores the flags. I will try one with IVTC to see.

If you determine that your source is truly interlaced NTSC, check out my "Fawlty Towers" thread in this forum.

The problem isn't the source. It's FILM 98%. Using force-film i get perfect picture but I want to have it 29.97fps for the DVD player. I think the player has problems with it being 23.976fps because it has occasional freezes that aren't present when played on the computer(nothing to do with force-film). I tried 3:2 pulldown in TMPGEnc but it creates interlacing artifacts on the TV even(maybe bad settings). I tried just resizing the 29.97 movie but I get ghosting. Help.

First of all, 23.976 fps is a legitimate framerate for NTSC VCDs so your player shouldn't have problems with it. If it does, you might want to consider exchanging it for a different make or model.

Second, VCDs have a 352x240 resolution, which means that they can only be progressive. So if you do a proper 3:2 pulldown on them, there really shouldn't be any interlacing artifects. You need to play around with the settings a little bit more.

Which movie are you ripping precisely?

I'm trying to rip Autumn in New York. What settings would you use in TMPGENC?

@ spyder
I havn't tried it before, but it seems that there is a tool that can patch mpg files for 3:2 pulldown.

Just make your 23,976fps-vcd and then patch it with the utility, hope it works (because it is said, it works only with MPEG2, well who knows!)

This should help you. If you still have problems after encoding with av sync, auto-IVTC the movie even if it's 98% FILM.

Pulldown.exe will not help with MPEG-1 files. My problem is trying to convert 23.976fps video to 29.97fps which I realized is impossible for VCD resolution without ghosting or stuttering video due to duplicate frames. I'll just keep making Film VCDs.
