Exporting to Flash with Alpha Channel

[Robert Sharpe]

Dean,
When you say “exporting from timeline”, – I am exporting the keyed out video with alpha channel from my timeline through Quicktime conversion and selecting Animation, Millions of Colors+. When I bring it back in, though, the alpha is black and blocks out anything on Layer 1.
Thanks for trying to help! I’m sure it’s some simple little thing I’m overlooking.

Let me know when you figure it out Robert.

Will do Dean – you were right – changing the sequence to the Apple Intermediate codec didn’t help. I also tried exporting Animation at 60 frames, but that didn’t work either.

I am also having problems making my Video,

I key the blue screen, making the background black.

I export as a animation “millions of colors+”

Import into Squeeze, apply the On2 Vp6 codec… After its complete i cannot view the flv with the flv player, its crashing. So i dont even know if i am doing this properly anymore:(

Someone help!! 🙂

Robert,

I just realized what was missing here. When you export from the timeline as described, do not render the video before exporting.

Hope this helps.

I love when I find the thread that exactly pertains to my dilemma! Dean, I too thank you for your info. The not rendering is exactly what made it work. How.. what.. made you think to not render? Perfect!

I tried following the advice of not rendering the video before exporting from Final Cut, but then when I bring it into Flash, the video is frozen on one frame (although the background is transparent). When I render the video before exporting from Final Cut, it moves, but the background is not transparent. Any ideas? Also, can this be done without Sorensen?

Happy this worked for you Bryan. This forum has been a great resource for me as well.

Brett,

Assuming that the video exported from FCP plays properly in Quicktime, this sounds like a Flash issue, something that I know little about.

Besides Sorenson Squeeze, you can look at Episode. I heard that it now supports alpha when exporting flv’s but we have not tried it yet.

Ok, I have perfected exporting from FCP with an alpha channel and then encoding as a flash video. The only part I need help with is chroma keying in Final Cut 5. I have an HD camera that keys out pretty good with the built in chroma keyer in final cut pro. I have a very well and evenly lite green screen. However, I still get edges with green halos and jagged edges when I take it too far in the chroma key so I have to back off and then I have some particles floating around.

My question. Is there a really good chroma key plugin that is really a step above the built in one that would give me better results? Or am I wasting my time in FCP and need to buy Ultra’s Magic?

Thank you to everyone for their help.
