The top level track on my project contains an alpha channel. However, being the top level track the tracks below it are invisible.
I have read the "Compositing, alpha channels, and adjusting clip opacity" page. It tells me that I "can choose how to interpret the alpha channel in a file in the Interpret Footage dialog box. Choose Invert Alpha Channel to swap areas of opacity with areas of transparency, or choose Ignore Alpha Channel to not use the alpha channel information at all."
However, when I do this (ie. inverse the alpha channel in the asset) I get the following before and after results:
Summary of goal: I want to adjust the transparency of the top track so that the lower tracks appear.
If you want to adjust the transparency of a clip, you modify its Opacity property.
Changing the alpha channel properties in the Interpret Footage settings is for when the alpha channel of an asset is not being interpreted/used correctly by the application.
You need to pre-multiply your image - composite your image with alpha channel over black before you bring it into Premiere. Different file formats sometimes treat the alpha differently. E-mail me a still and I'll sort it out for you. Spectravideo@cox.net
