Transparent video over web page [ANSWER]

I'm trying to make a transparent video that I can embed into a web page over some background. The .avi file that VisonLab renders will be converted to a .flv file with Flash 8 Video Encoder.
Unfortunately after chroma keying the video doesn't appear to be transparent, but with a black background around my character.
Does anyone know what the Rendering settings should be so I can get the correct .avi file that Flash 8 Video Encoder can correctly convert into a transparent .flv file? Does it have anything to do with the Output Type - should that be "standard" or "alpha export"?...

Try alpha export as transparency is 0% alpha, while normal footage is 100% alpha (also known as being opaque)
If your background is a solid colour, why not make the background in VisionLab that colour? If it is an image, however, it will be much more difficult.

Thanks, I tried alpha export and it worked. The final .flv file looks good and it's transparent. The .avi file though looks weird, it's showing a rough, wide black contour (without the blur applied to the alpha channel) around the character, but after conversion to flash looks perfect.
The background is an image and not a colour. I thought of cropping the portion of the image in which the video will show and make it a background, but it's too difficult to match the position.

I'm glad that it worked out.
