Hi, I'm using Vegas 7.0 and macromedia flash. My purpose for my project was to video-tape myself, chromakey the background, send the video to Flash, and created an animated background with me inside usign flash.
I know how to use chroma-keys, and it works fine inside sony vegas 7.0. However, when I export/render the chromakeyed movie (with transparent background) as avi, the background turns out black- not transparent. When i import this movie to macromedia flash, the movie's background is black, not transparent. Can anybody help me with this problem? sry for my lack of video editing knowledge.


**not sure but is it because avi or wma doesn't support transparency? or maybe i should use another video editing program?

I'm not sure you can do that - at least I don't know how. You could add the animated background in Vegas, but I'm not sure about exporting transparency in a video file. When you chroma key in Vegas you remove colour and the track below shows through... but if there is no track below it is black by default.

Why not create the background, export it to Vegas and key it in behind you there?

you cannot have "transparency" in AVI's, although you can use the black background and replace it with something in flash (or any other colour), I just learnt this from a Flash training disc the other week!
