Cropping and Resizing

§Daisuke · Post by **§Daisuke** » Sun Jul 31, 2005 7:17 am

Okay so I know that Cropping and Resizing is best done via Avi Synth. But my question is how do i know what wright in the code.

I've got an .avi from a friend who made some stuff via premiere but it has 2 black bars on each side... how do i know what to put in the avs file.

Resizing.. after cropping out those 2 bars i want to resize the clip to 720x480.

If you don't understand what i'm asking for i'll try to explain a little clearer.

Code: Select all

Crop(16,0,-16,-0)
LanczosResize(720,480)

This will crop 16 pixels from the left and right sides.

okay but when i try to open it up with Virtual Dub this is the error i get:

Avisynth open failure:
AVISource: Couldn't Locate a decompresser for fourcc
(C:\Documents and Settings\Daisuke\My Documents\My Videos\beggining.avs, line 1)

What is fourcc. I've checked my first line. It's perfect.

A fourcc is a four character code. It's four characters in an avi file that tell the media player what codec it needs to use to decompress the avi file. For instance the fourcc for divx 5 is DX50. TO check the fourcc of a clip, load it into VirtualDubMod and select File>File Information...

If that doesn't help you, post your script here with the fourcc code of the clip you're trying to load.

Cropping of the black bars without cropping of any of the image just takes a little trial and error.

okay. This is my script:

AVISource("C:\Documents and Settings\Daisuke\My Documents\My Videos\Begginning.avi")
Crop(16,0,-16,-0)
LanczosResize(720,480)

also i can't find the fourcc because VirtualDubMod won't open it.

What error does vdubmod give when you try to open it? (The file Begginning.avi, that is).

You can use the motion tools in premiere for zooming in and the like. Use scale to zoom in, and Position to move the clip. You'll find the motion tools in the effects properties window (this is from memory though).

As a second thought, if you can play beggining.avi in mediaplayer, you might try using DirectShowSource instead of AVISource.
