1. Re: How come AE cannot interpret Alpha Channel from ProRes4444 ?
Johnathan A. M. Dec 18, 2011 9:46 AM (in response to ryan_khoo)that black part may be the alpha channel, between "active camera" and the preview resolution (full) there is a little checkerboard pattern, click that, and it will show transparancy in the checkerboard, sorry if you've always tried this, but start with the simple solutions first

Rick Gerard Dec 18, 2011 10:00 AM (in response to ryan_khoo)Did you check the file interpretation in After Effects? I've never had a problem with ProRez 4444 files.

Q1. This is part of the basics. Select the file you want to interpret in the Project Panel then either right click or go to the menu File>Interpret Footage>Main or use the keyboard shortcut Alt/Option + Ctrl/Cmnd + G
Q2. Nope... It's always worked. There were some gamma problems for a while, and a few other bugs here and there with ProRez, but if you're Mac is up to date you should have no problems with the alpha channel.

Thanks Rick for your help, I really appreciate it as I am not quite familiar with AE.
Q1. I did the steps you taught me & a new screen pop out. But under the "Main Options" tab, the section under Alpha, there are 4 choices (Ignore, Straight-Unmatted, Premutliplied-Matted with color, Invert Alpha). But all these was all greyed out. Any idea why ?
Q2. I am using Mac & I just checked my AE CS5 is Version 10.0. I am a student and i bought the Student Edition. Student Edition not allowed to update, right ?
Thanks

Rick Gerard Dec 19, 2011 9:26 AM (in response to ryan_khoo)Run the updates. And yes, you can upgrade, update, do anything you want with a student edition.

Yes Rick, the problem solved by updating to Version 10.0.1.
I am on Mac. My previous version was ver 10.0.
After updating, I re-import the alpha channel files with ProRes4444 & AE can recognize the alpha channel.
Thanks again, Rick, you have been great.
Merry Xmas to you & everyone here.
Cheers
