It's properly transparent in AE at least. I export it exactly like this to an AVI file, then import the AVI in premiere, and blam-o black background again

Your having the same problem I'm having which I made a thread about asking how to make a section of my video remain transparent after an export. At this point Scintilla suggested I use a codec/format which supports an alpha channel ( e.g. setting lagarith file to RGB32).

Which I did and it showed up as a black background rather than tranparent. (There was transparency in AE).

Okay, turns out I *have* done this before... looking at the file, it's uncompressed RGB. Works fine in Premiere Pro with the transparency and everything.

In AE, you have to set "Compression Type" to "None" and "Depth" to "Millions of Colors+".

I tried that and it still failed. Anything wrong from the screenshot?

I think you have a newer version of After Effects than I do. What are the other options for "Color" besides "Premultiplied (Matted)"?

If it's the same as mine (which it appears to be) it should be "Straight(Unmatted)" as the second option.

I tried "Straight(Unmatted)", and to my suprise it failed once more.

This may sound stupid... but if you are using Premiere 1.0 or higher, you should have keying filters. Have you tried cutting out what you need in the video and setting it on a background that has a solid color that does not appear in your source and then keyed it out in Premiere?

Your saying to key out the ''black parts'' so the video underneath shows through?

That would defeat the point of this because I can just do all the work in AE and export the whole thing ready to put in my editing program.

well for transparent background. I Use HuffUV and all the other settings you have. Lagarith didn't work for me so try HuffyUV. Then you import your file and set the transparency to "Alpha Channel" and it should work.
