How can I make an AVI transparent?

Hi there



How can I make an AVI transparent?. Like I need to convert the background color(say Red) of that AVI in to Transparent.



Ex.

I am doing AVI for file copying, similar what Explorer's got. Here I have image of two folders and some moving objects. I want to make whole of its background Transparent.



I am using TAnimate to this. But setting Animate's Transparent property to TREU does not help me. We tried out making both Uncompressed and Microsoft

RLE AVI file formats. We are using Delphi 3.1

I had downloaded the Dream Controls from the Dream Company. *http://208.230.134.248/dream-co/ *- They have an AVI player that plays the sound of AVI's plus can do a transparent background. *I don't know if it would help your situation, but I thought I would at least mention it.
