This might be looking for trouble...

We took 2 QuickTime files, one "Animation with alpha" and the other Apple Intermediate Codec, cut them together after eachother in QTP and saved as a reference file. This way we have alpha in the start where we need it and then a less consuming format for the rest of the film.

Anyone else tried this? Just thought it was a little fun...

If you intend to use this in Catalyst you'll only be outputting one file, one format.

When you create a composite and output, you'll have to pick the format. Since Animation was first, that is the one that the system should default to. So the entire output becomes a single file in Animation. This is unless you chose AIC as your output. Nevertheless, you aren't doing anything other than rendering a composite which becomes a single layer.

You didn't really do anything except raster.

technically - i think it will work- its a reference movie- quicktime will automatically decompress using correct codec for each frame.
the structure of reference movies and quicktime supports this

i believe multi track movies with different codec on each track at different times will also work.

not to be recommended though
