Help with Transparent Web Video
Before I get going, I should let you kind people know what programs I am working with.
-Final Cut Express HD
-Flash CS4
-Flash mx 2004
-Visual Hub
-Final Cut Studio HD once I find my old discs, soon hopefully.Now, my problem. I am trying to make something akin to the video at “https://www.dove.org/”
I filmed the greenscreen footage, successfully keyed it out, and have exported using FCE set to “Animation, million colors +” as I read to do.
From there, when I drop the exported sequence back into the timeline, it successfully carried the alpha channel. Now it is my understanding that I need to somehow convert this .mov to a FLV for it to work correctly?
I tried going about this using Visual Hub, as well as Flash CS4. I am hardly familiar with flash, so I am left at a dead end. Any help would be much appreciated, as I am not about to tell my boss this relatively simple project needs outsourced!
Thanks in advance!

there lies the problem. flash is not by any means easy.
even my web developer knows this and he’s been using
flash since it first came out.Your answer will be at a Flash forum.

Your answer will mostly be in the Flash forum, and then you’ll probably come back looking for this:
Re: Exporting alpha channels in Final Cut Pro
by Mark Pope on Sep 22, 2006 at 7:32:41 pmI don’t know of a way to do it directly, but here’s something I tried. I put the Quicktime Movie with alpha on V1. Then I put a White rectangle on V2, scaled it up to fill the screen. I selected the white rectangle (V2) and used “composite mode” (under “Modify”) and chose “Travel Matte – Alpha”. Rendered. Now I could export that sequence and have the equivalent of “just the alpha channel”.
As I recall this is part of the process you’ll have to go through on the video side.
Cheers,

If your objective is to have a flv with an alpha channel you need to use the On2 VP6 plugin with your flv encoder. I do all my flv encoding in Squeeze which has it. I’m fairly certain it is included with Flash Encoder, too. You would take your animation codec + alpha clip into the encoder and make your flv. Once you have the flv with alpha you can drop that (in Flash) over any Flash background.
