Hello,
I am using snowmoons excellent avs script to speed up a Divx AVI to 25 fps, using the following lines:
AVISource("test.avi")
ResampleAudio(44100)
assumeFPS(25, sync_audio=true)
bilinearresize(480,432).addborders(0,72,0,72)
The source DivX has 48kHz stereo (encoded with MP3), has 23.976 frames/second, and a dimension of 640x384.
If I open the resulting .avs in Virtual Dub, it gives me 25fps, but the audio part is messed up, showing mono (one channel) with 45983 Hz...
I guess this value is due to the speed up of the video, so what can I do in order to get a 44.1 kHz audio stream? I wanted to use this method to avoid having to extract, pitch and convert the audio with CoolEdit, can anybody help me with this?
Another option would be AviFrate to change the frame rate in the DivX header to 25, but I wonder if AviFrate also changes the audio speed to match the increase playback in video.
Comments?
Thanks a lot in advance

I don't think you want to do anything with the audio after you'ved use AviFrate. Personally, I've never tried AVISynth to do 24->25 fps conversion. I know cooledit takes a while to downsample and convert, bet you get a first-class result when you're done.
