  Alpha Channel is black on TL

  Posted by Diggitydoggy on September 1, 2006 at 2:59 pm

  At random my timeline will not see trew alfa clips like lower 3rds… What should be a hole is black. Not just the canvus but renderout playback. Is there a setting that would tell the timeline to not see-threw alpha channel stuff? This has happened before and then it fixes itself? So I think I’m hitting a shortcut key to toggle this on and off???

  Randy,

  What format is your graphic, and where did it come from (AE, Motion,etc.)? Try scrolling over in the browser and setting the alpha setting for your clip to black.

  I used to have a lot of trouble getting alpha channels handled properly in FCP. You just have to give it what it wants. For instance, I don’t believe FCP likes / recognizes pre-multiplied alpha channels (I could be wrong). When I export from motion with alpha, I uncheck the pre-multiply alpha box on the output tab of the export options dialog. Like buttah.

  I think a little more information will help people narrow down your problem. Troubleshooting is all about narrowing down the possibilities.

  Zak
