Green Screening??

[Caios]

I want to bring a movie into flash that has a green (0,255,0) background with a poser character in front of it. Then make the background transparent, so it can be placed over the flash scene without obscuring it all.

Any ideas? Am messing around with Color.setTransform() but not sure if that gonna work. Dont want to have to cut the green out of the frames one by one in photoshop.


So basicly I need to import a movie that is partially transparent?

You would more then likely have to take care of the greenscreen compositing in either After Effects or even Premier.

What video format supports transparancy? I know you can do green screening in after affects but how can I export it to flash?

[Jfrasier]

You use a video editor to edit your video, then bring that into After Effects or whatever program you use to composite. Once you have composited your background export it out as JPEG frames then import them into a MovieClip in flash. The only video format that supports green screen is raw DV, or Uncompressed Quicktime/AVI

Hi.
I think Flash will import PNG files with transparency. So you could convert your video to a PNG sequence using some software (Quicktime Pro can do that).
Then you can import the PNG sequence into Flash.
But you are probably best off creating the whole scene using a software that is designed for chroma-keying and then converting the composited video into Flash when you're finished.

You might be better off with (shiver) a MAC in trying this one, have importing transparent movies into flash on a PC and they didn't seen to work, although it worked fine in MAC. For some reason there are video and transparency options in flash that are only available in the MAC version

I have never had that issue Muple and I am a strictly PC compositor

I've never heard of that on Mac either, interested though.

I prefer image sequences of 6 fps using .pngs, but this can get pretty heavy on bandwidth for long movies. Use sparingly, or compose in another program.
