DVD2AVI and 59.94 progressive

[nnigam]

I have an HD program that I recorded. It is 720p at 59.94fps. I would like to burn this to dvd. I process this file with dvd2avi2 and I get my d2v file. I then use an avisynth script to change this to 720x480 resolution and use assumefps to get it to 29.97 fps for dvd and process the avs script with QuEnc. When I generate the dvd file, I see that audio synch steadily increases. I finally guessed that this is because my video has been dropped fro 59.94 to 29.97, but nothing is being done to the audio. How can I correct this, or is there a filter in dvd2avi that I can use so that both audio and video are reduced to 29.97fps for dvd authoring.

assumefps(29.97) on a 59.94 fps video will slow down your video by a factor of two!

for this purpose, better use selecteven()

or even better either
IVTC it to 23.976fps if it has a 2:3 Patter of repeating frames.
using

selecteven().decimate()

or if your video has only unique (non-duplicated) frames in it, reduce it via the following script to 29.97fps interlaced:


source("blah.xxx")
lanczosresize(704,480)
assumetff()
separatefields()
selectevery(4,0,3)
weave()

That explains why my audio was getting out of synch. Since the video is progressive, all frames are unique. I will try your script instead.

Thank you.
