Border Control

The Border Control VirtualDub filter was designed to allow you to manipulate the regions at the top, bottom and sides of a frame.

This might be a useful option if you are capturing video for use in say a fixed VCD format. If you crop your video to get rid of rubbish (say from VHS capture) you normally have to add a solid border or resize to get the clip to the right dimensions for your MPEG encoder.

I've heard from others that MPEG coders don't like solid borders because although they compress OK, the transistion between the picture and the border often causes noticable artifacts (unless the borders are a multiple of 16pixels).

Resizing can be undesirable at times, especially if the material is interlaced.
