Transparent video for webpage
I have a potential client who wants to shoot an actor in front of a chroma-key background. Hey want’s me to give them a transparent file for their website. He gave me this website:
wwww.ispeakvideo.com as an example of what they’re looking for. Has anyone here done this before and could you please give a step by step guide to how it’s done? I edit with Adobe Creative Suite 3 Production Premium.Thanks in advance,

Hi Joel,
We’ve done this a lot, and it’s simple really. The website was created in Flash using a .flv with a alpha channel for the video clip. Some web designers I’ve worked with want a uncompressed file with alpha so they can compress their own .flv, others want me to do the compression. Either way, when you pull the key for the footage, export the clip with the alpha channel present (RGB+Alpha) from your application. Note some codecs don’t support alpha (ie: Blackmagic QT). I usually use Quicktime None with millions+ colors (the + will get you the alpha).
Then import that file into whatever encoding software you use. It must support Flash 8 video (with the On2 VP6 codec) and alpha channel embedding. I use the Flash video encoder which comes with Flash. Then just encode as needed with the exception to be sure to check the ‘encode alpha channel’ switch (that’s what the Flash encoder calls it) in the video settings tab or area. The web designer will then be able to incorporate the resulting .flv with the transparency intact.

Its Flash video in its most creative use yet. I am going to try this over the weekend. And will report back.

Thanks Troy. I knew it would be a relatively simple process, I had just never done it before. I appreciate you taking the time to explain in such detail.
