How to convert at 29.97 fps AVI to a 25 fps AVI

[Swin]

Hi,

I have been trying to convert an 30 min AVI file to and AVI file with different resolution and frame rate with no joy so far.

The original AVI is 512x384 res at 29.97 fps, and I'm after reducing the resolution to 400x288 at 25 fps.

I have tried this in Virtual Dub but all I seem to end up with is an AVI that is somehow 5 min longer than the original with the sound sync way out.

Is there a simple way of doing this?

See if this can help.

Just to kind of answer my own question and possibly to help other perople who have just started this game like myself, I have found a fairly simple solution that so far seems to give OK results with no change in audio pitch or movie length. It doesn't give you a modified AVI, but the actual intention of my question was to get the AVI into a format that could be easily converted into a PAL VCD.

I have been using DVD2SVCD for some time and the AVI2VCD feature inbuilt. Simply load the VCD setting into DVD2SVCD, change the sourece from DVD to AVI (all on the Misc tab), click "Edit as part of Video Encode" on the Frameserver tab, select your AVI and press Go! - OH and make sure the the NTSC to PAL tickbox is NOT checked.

When the AVS script pops up, add the line : -
ConvertFPS(25)

to the bottom of the script and alter the Resize line to read :-
BicubicResize(352,288,0.0,0.6)

This takes care of the PAL conversion. I have messed with other settings such as CHnageFPS and a couple of more commands, but I have found this to be OK so far. I have a few more scripts to test though.

Your script should then look like this: -

LoadPlugin("C:\PROGRA~1\DVD2SVCD\AVISYN~1\Mpeg2dec \mpeg2dec.dll")
AVISource("C:\Stuff\SER1~1\FRIEND~2.AVI",False)
ConvertToYUY2()
ConvertFPS(25)
BicubicResize(352,288,0.0,0.6)


Hit OK and you will end up with a converted AVI ready for burning to VCD. No slowdown in video or audio and a fairly jerk free audio.

Basically, this automates the steps as sugested in the link above which I personally found a lot easier to deal with.
