Hopefully a Simple Avisynth Question

[daveoggy]

I would like to take the size of the cropped image and reduce it by a percentage. Something like this:

DirectShowSource("F:\batman\batman.mpg")
AutoCrop(mode=0,hMultOf=4,samplestartframe=200,sam ples=5)
LanczosResize(**Autocrop Reported new Width x 0.5**,**Autocrop Reported New height x 0.5**)

I know the above is nonsense but what would be required to achieve this?

You can try this...

clip=DirectShowSource("F:\batman\batman.mpg")
LanczosResize(clip.width()/2,clip.height()/2)

you will have to be careful with non-mod_x resizes. Some filters/codecs will only work with specific size, i.e. mod8, mod4, or mod2 sizes.

Brilliant, thank you. One question though, I understand where the 'clip' has come from but what about width() and height(), are there any more such commands in Avisynth? Where can I learn about them?

If you have Avisynth installed, there should be a full documentation package installed with it. If not, go to Avisynth.org and the Doom9.org forums.
