All I'm trying to do is have titles appear over an animated background. SIMPLE! Yet I get a black (not transparent) letterbox over the motion loop and that's with the titles on a video channel above the background! Help, you guys! MANY THANKS!
Exactly how did you create those Titles?
If in PrE's Titler, and you have ONLY added Text (no Shapes), then the background should appear as black, which is actually Transparent (as this has thrown some, in PrPro CS 6, Transparency appears more like the checkerboard in Photoshop).
If you created the Titles in another program, you need to do so over a Transparent Background, and then Save_As a format, that supports Transparency, such as Photoshop's PSD, PNG, GIF, but NOT in JPEG.
Please let us know a bit more and good luck,
OK, that eliminates a lot of potential problems.
Can you post a couple of screen-caps:
Those should clearly show exactly what you have, and what you are seeing, and maybe someone can pick up on the problem.
Thank you, and good luck,
