I would like to be able, with command line tools where possible, to convert a 29.970 fps avi to 25 fps Pal.

I have managed to write a gui program which does all my conversions for me, swapping between frame rates and quality with a couple of button clicks, but have been unsuccessful in converting the above framerate.

I have Besweet, VirtualDub, VirtualDub Mod, AviSynth 2.5 and that kind of thing if these can be used?

I tried writing an avs file that told virtualdub mod to read the audio and video as 25 fps and timestretch the audio but when I tried automating this with the virtualdub script it wouldn`t open the virtualdub script itself.

Then I tried besweet ripping the avi audio to mp2 at a video framerate converted to 25 fps but this fails. Can anyone advise please

Telecide().decimate()


If the source is interlaced then look here to obtain aprogressive solution:

Or if its for you ok to end up interlaced then.

Kernelbob() # search for it on forum.doom9.org
BilinearResize(... PAL Resolution here...)
ConvertFPS?(50)
SeparateFields()
SelectEvery(4, 1, 2)
Weave()

Dumb question, but do you mean to use them without any parameters in an avisynth script?

Would I still be okay to add an assumefps(25) after or does this automatically change the rate?

Thanks for the patience
