I ran these AVI files through TMPGenc that were 23.976fps and I put the output as 25fps PAL. After every second it will freeze for a really short while, but still enough to be annoying. I guess it's TMPGenc filling up the missing 1.3 frames. To get rid of this was I supposed to use 3:2 pulldown? I found a program called Pulldown (http://www.digital-digest.com/dvd/downloads/pulldown.html) that is supposed to change it without re-encoding the movie but it doesn't seem to work. I've used it multiple times with different settings but the freezing is still there. Am I doing it totally wrong? What settings I'm I supposed to use on the file using Pulldown? Am I going to have to encode the movies again?

All you have to do is to choose 25 FpS PAL as Target and in Setting -> Advanced -> Do not frame rate conversion.

Or open the AVI in AVISynth an include the following command:

AssumeFPS(25)

I suggest you to use an WAVE-Editor to correct the Pitch of the Audio-Part.

OK, what method is better:

1. The method Kika said, but I still don't understand how you can sync the audio in by changing the pitch:confused: Isn't it impossible to sync the audio if you are dropping 1.3 frames a second?

2. Use TMPGenc to auto do it using GOP. The settings TMPGenc use are:

I=1
P=4
B=2
output interval=1
max No. of frames in GOP=15

Is this the best way to get it as smooth as possible? I can still notice a bit of chugging but it's way better than it was before. Do you use those settings or something else? Guess I'll have to put up with a slight chuginess
:(

EDIT I got it to play in one of my dvd's players with the 23.976fps and 704x400 ratio (which is way outta wack). I couldn't change chapters, view in panscan (could only do letterbox) and could only fast forward at x2. Would this be a ratio/size or framerate issue? Do you reckon if I just use the proper 704x576 and the 23.976fps it'll work?

If you do the TmpgEnc way by using "Dont change Framerate" you will just pitch up the video decoding playback for TmpgEnc internally before it gets encoded.
The same as if you would simply use an AssumeFPS(25) at the end of your script.

When doing one of these steps above no matter which one, you will have to pitch up the audio separately by demuxing the audio in VdubMod and convert it in Besweet using the "framerate" conversion options in the OTA section.

BUT as your source is an AVI which comes with audio, you can simply use...

AssumeFPS(25.000,true )
SSRC(44100)

The "true" command keeps audio in sync by "changing" the khz rate of the audio, so we do use SSRC() to "convert" the audiorate to our target purpose, like in here for instance SVCD, if you would choose DVD as target, then choose 48000.

Thanks very much incredible, it worked :D But just one thing, why doesn't VdubMod wanna read the audio but just the normal Vdub does? The audio is AAC.
