Alpha Channels with FX 9.2
Hello,
I am using Boris FX on an animatic i am cutting in Final Cut Pro 6.0.3. I am using PNG stills as my media.
For some reason Boris will not read my Alpha channel. I have tried adjusting the settings. FCP sees the alpha just fine, but as soon as I pull Boris FX onto the image, it loses the alpha.
This is my first time using Boris FX. Am I missing something? Any help would be greatly appreciated.
Thanks!

Hi Wyatt,
The problem is that for some reason FCP is telling Boris that the image doesn’t have alpha. This is real easy to fix.
1. enter Boris FX
2. select V1 and click the disclosure triangle to expose Face track
3. select the Face and in the Controls window change Key from No Alpha to Straight AlphaAfter that it should behave as expected.
Cheers,

Fantastic!
Thanks so much for your help!

I’m not sure it’s exactly the same but I’m experiencing similar problems.
When I export animations from Boris RED it looses it’s alpha properties. So neither in the file preview or the imported clip in FCP do I keep the alpha. Serious problems here. Oddly enough, I,ve experience these things only after I went from trial version of Red to official version. Go figure.

Hi Jean-Francois,
It may be the export settings you’re using. Not all compressors support alpha. I recommend using the QuickTime Animation codec and be sure the Depth is set to Millions of Colors +.

Man can I can’t beleive it ! All this head cracking for so many hours and … you’re right. I did use the QT animation compress but did not set it to millions colors + … it was only at millions colors. And well..that’s it.
Many thanks.
