  • CS5 alpha channel import

    I recently upgraded to CS5. Since then, I’m having trouble using the alpha channel from clips that I import. They were working fine before the upgrade. Has anything changed with CS5, or are there any known bugs with this? Thanks.

    Let me update with a little more information:

    I am using an AJA card, and so tend to use the AJA presets. The only preset this doesn’t seem to work on (from the ones I’ve tested anyway), is the AJA SD DV timeline setting. The AJA SD Uncompressed works fine. The standard DV-NTSC Adobe setting works great as well…

    Have you installed the Premiere Pro CS5 (5.0.2) update ( https://bit.ly/djiyh4 )? That update fixes a lot of problems.

    Great idea – I had not gotten the update. I ran the update and restarted the computer. However, still no luck…

    When you say “clips” you import.

    Do the same clips work fine in one type of project, but not DV?

    or are you rendering different types of clips for each project type?

    From??? After Effects?

    The ‘clips’ I’m referring to are rendered files from After Effects. They’re 720×480 AVI, lossless with alpha. This is the only type of clip I’ve been using. And that video clip will work fine in all the types of sequences I’ve tried except for AJA SD DV.
