Changing Framerate Converting SVCD to VCD ??

[JustJay]

I’ve downloaded quite a few cartoons (classic looneytoons) in SVCD ready format from newsgroups that I’m converting to VCD trouble is that when I frameserve them from Virtualdub-(mpeg2-ac3) to TMPGEnc the length of the video is incorrect (7minute cartoon runs about 5 minutes after conversion) and of course the sound is out of sync as it appears to remain the original length (I checked this by ripping the sound to a wave).
Ok here’s my question, in Virtualdub I can check the “change so video and audio duration match” under framerate options then encode using NTSC Film, this results in a 23.97 framerate with the audio in perfect sync and the correct playing time of the video – BUT – the original SVCD was 29.97fps according to both WinDVD and Virtualdub file information. What’s going on here (yup I’m a noob) was the original 23.97 and the file info wrong, or what am I doing wrong? Help…..arggggh {drowning in a sea of confusion}

One thing yoou might do that would save time and it easy and fast.

Download the mainconcept demo at maincomcept.com.

Then you can encode from SVCD to SVCD or SVCD to VCD in one step and in a few minutes it should come it really good. On the demo, it does leave a water mark in the upper left hand corner that is no big deazl, but the demo is 100% functional. If I done this lots of times trying to get some looney tunes stuff. I sometimes encode vcd to vcd in Mainconcept and it always inproves everything.

TMPGEnc will accept mpeg2's as well if you install the mpeg2 plug-in from the Tools section.

Thanks for the quick response jolo and Zippy, maybe I should have been a little more clear in my first post, after letting VirtualDub change the framerate the final result works fine so no problem there the vids look good and play smooth. What I'm trying to figure out is what the heck the framerate was supposed to be in the first place (just to satisfy my curiosity). In the meantime I've loaded the SVCD into DVD2AVI and it tells me 23.97 Film Progressive (what I'd expect being animation?) so why do VirtualDub and WinDVD both tell me it's 29.97? A glitch in the way they report their info? Duh!
