Running Deinterlace Code - audio issues

[22west]

Hi All,

When I deinterlace my video with the code below I get a nicely deinterlaced video - but the audio is out of sync. For a 1 hour video the delay near the end of the video is significant. Note that the source .avi (the interlaced capture file) is completely in sync.

SetFilterMTMode("QTGMC", 2)
FFMPEGSource2("Video 2.avi", atrack=1)
ConvertToYV12()
AssumeTFF()
QTGMC(preset="Slower", EdiThreads=3)
BilinearResize(720,540)
Prefetch(10)

I read in another DigitalFAQ thread (cant find it now) that if I change FFMEGSource2 to AVISource, the audio will not be out of sync. See new script below :

SetFilterMTMode("QTGMC", 2)
AVISource("Video 2.avi", atrack=1)
ConvertToYV12()
AssumeTFF()
QTGMC(preset="Slower", EdiThreads=3)
BilinearResize(720,540)
Prefetch(10)

When I go ahead and do this the video is again nicely deinterlaced again but now the audio is gone completely - no sound at all.

Does anyone know what might be the issue here?
The script is written using AvsPmod v2.6.6.7 and I am running it in VirtualDub 1.10.4.

Note - I am quite new to using this code so go easy on me.

Thanks,

Load a script with just the single line AVISource("Video 2.avi") and nothing else. Is there audio?

Ok, good suggestion. I just tried that and again no audio.

Sorry my mistake - I didn't do exaclty what you said. What I did was deleted all the other lines and ran what was left:

AVISource("Video 2.avi", atrack=1)

This gave no audio. So then I ran what you said :

AVISource("Video 2.avi")

With this I get audio.

If the source video is VBR VFR then it will go out of sync.

Sorry, I meant VFR (variable frame rate).

I don't know if it's possible to deinterlace VFR video, but you can always decomb, and somehow preserve the frame timings.
