Answer to question 1: send a "colorspace RGBA" message to pix_film before loading your quicktime.
In my experience only Final Cut can render properly the alpha channel and there is a trick to it:
-exporte with "FCP movie" (not Quicktime)
-go to custom settings
in QT video settings select ANIMATION
-next, still in QT video settings you go to ADVANCED and select
MILLIONS COLOR +
- next, export with RECOMPRESS ALL FRAMES activated or it will not work

hi list i have 2 questions:
i made a patch that makes an fade between 2 videos with gem,
using alpha and colorRGB it works fine with avi files,
but doesnt work with mov files, why is this? is this a codec issue?
if so, which codec of mov files supports alpha with gem?
in using pd 0.38.4 with osx...
my second question is:
im creating videos with after effects,
and theres a compression option that allows you to make alpha channels
(for example making a video with holes,
that allows you to see the image that is in the background
..... that option is:
depth : million of colors +
is it posible to see the videos with transparency in gem?
thanx .... bye

I guess it's more complicated than making "holes" in the movie.
I haven't tried yet, but
it might be possible to use [pix_mask] and [pix_multiply]
for having this kind of effect?
