Hello,

Hope someone can help.

I am trying to get a flash vid to display in transparent mode.

I have set parameters to vmode and transparent, but still shows black background.

Really appreciate some help here.

Cheers

Ken

you need to key out the background (alpha channel) and encode with on2 "vp6a"

it's the only format that supports alpha channel for flash

Thanks for answering that one, PDR0.

For reference, On2 VP6 is the standard video formats saved into FLV.

I've not yet had the time to test this out. I'd try it in Adobe Premiere Pro CS4, then encode out with the Adobe Media Encoder. Or CS3 and the Flash Encoder. I'll give this a quick try here in a few more days.

Thanks.

I took one of your videos and did a rough roto job just for illustration purposes, encoded to vp6a, then wrapped into .swf with adobe flash

You have access to vp6a with Adobe Media Encoder or After Effects. If you're keying in AE, I'd recommend exporting a lossless format with alpha (e.g. uncompressed, huffyuv, ut video codec), then use AME (because AE only does 1 pass encodes, but you can do 2pass and have more options with AME)

I included a html file so you can play with it offline locally and see what's going on

note - some flash front ends do not support alpha channel (e.g. some versions of JW didn't for a while), or they need special code to allow for transparency

(see attached zip file)

There are many tutorials out there, for example here is a older pdf you can download with illustrations:

Note that you can attach files directly posts. I've edited the above post for you.
Those "file hosting" sites eventually delete files, and then threads become useless.
See How to Upload/View/Download Images+Attachments

And thanks for posting with that example.
