IVTC w/ Avisynth - CCE problem

[acenuts]

I've been trying to do IVTC w/ Avisynth to CCE 2.5 but the video always comes out slower than the audio. My steps for SVCD/MPEG2 creation:

Avisynth w/ IVTC plugin -> CCE 2.5 w/ progressive frames checked, 3pass VBR -> pulldown -> bbmpeg

Is this possible at all? Has anyone done this right?

Don't do the audio with CCE through AVISynth - do it separately with Toolame/TMPGEnc or just TMPGEnc.

In my case, I use TMPGEnc to do the IVTCn then VFAPI to take the .tpr project file and make a "pseudo-avi" file for CCE to use .. Never had a video sync problem.

I don't do audio in CCE. As for IVTC thru TMPGEnc, I'm interested in getting Avisynth -> CCE way to work if it's faster and/or better.

On a side note, doing IVTC thru TMPGEnc creates movies that are just a little choppy for me.

hmm, your method seems fine, i've done it many times before. can you post your avisynth script for me, so i can take a look?

also, you're doing dvd2avi -> avisynth right? and you don't have force film checked or anything (altho if this was the problem, you'd probably get an error somewhere, and the video would be faster than the audio, not slower)...

Yes, I'm doing dvd2avi -> avisynth w/ force film unchecked.

Avisynth script
----------------------------------------------------
LoadPlugin("e:\program files\mpeg2dec\mpeg2dec.dll&quot
mpeg2source("1.d2v&quot
LoadPlugin("e:\program files\InverseTelecine\inversetelecine.dll&quot
Doubleweave
InverseTelecine(40,10,15)
BicubicResize(480,480,0,0.75,10,22,720,480)

-----------------------------------------------------

And you're right, the video comes out faster than the audio.

I think if you intend to do IVTC, maybe you should think about using TMPGEnc's "Auto" function, save the video-only project file, then convert the project to a VFAPI .avi file.

This way you can encode audio with TMPGEnc to an exact source range (select "audio only&quot, then save project (select "video only&quot and convert it with CCE. I believe any and all filters, IVTC, cropping, resizing work just as they would in TMPGEnc.
