23,976fps to 25fps conversion

[ziegel-tom]

Hello,
this my first thread here. My question is not that easy i thing, i got that movie ripped to divx with 23.976 fps. Here in europe we like to see the movies with 25fps, so that's not all. First thing is to upgrade the movie to 25fps with VitualDub but then there is my real problem, the sound is not synchron to the movie no wonder 23.976fps is slower then 25fps so the audio has to be compressed and how to do that with VD or any other freeware programm is my question.
Thx for help

Hi Ziegel. Try converting the audio to mp2 with Besweet (it does the framerate conversion too) and then encode the video with CCE or TMPG or whatever software you like.

I myself use CCE with avisynth frameserving. You can do the conversion within avs script, like this:

-----
LoadPlugin("E:\.....\textsub.vdf") #subtitles filter
AVISource("F:\.......\movie.AVI") #the divx goes here
ConvertToYUY2()
TextSub("E:\......\subs.ssa") #subtitles file
AssumeFPS(25,1,True) #this is the conversion to 25fps
#Sharpen(.4) - not using it for now because it crashes CCE
BilinearResize(480,446) #this is what I use for resizing
AddBorders(0,65,0,65) #same as above
ResampleAudio(44100) #helps cce not crash
-----

Hope this helps.
Bye.

I have the same problem but AssumeFPS(25,true) does not shrink the audio. Do you mean that this shrinking can be done with Besweet (I don't know the prog).
Or is the trick your syntax
AssumeFPS(25,1,True)

where I can't figure out what "1" does because in the official doc there it goes:

AssumeFPS(clip,new_fps[,sync_audio])

Download BeSweet and the BeSweetGUI (new versions were just posted on the front page). one of the options is "change frame rate from xxxx to xxxx". just punch in the correct numbers and it does the conversion while converting the .ac3 (or whatever your soundtrack is) to .mp2. If you are using a divx file you will have to extract the audio track from the file, using vdub and then have BeSweet convert the audio track.

I don't think avisynth will adjust the audio, but even if it does, BeSweet will probably do a better job.

Wmansir is right, avisynth won't do anything to the audio.
What I suggested was to use Besweet for the audio conversion and avisynth frameserving for the video part. Just because it's a lot faster than virtualdub. But you can stick to virtualdub if you want... ;)

As for the AssumeFPS(clip,new_fps[,sync_audio]) options, I'm not sure of what they mean, I just copyed them from the avisynth script DVD2SVCD created for me in a earlier encoding job. I prefer to encode by myself (i.e, without DVD2SVCD help) when doing Divx to SVCD conversion, I get fewer problems.
