Hmm... I have a simple QC comp that reads a .mov file from disk,
adds bloom to it, and outputs it. If the exported output .mov file
is only 8k, that means its referencing not including the source
movie file, so I would need to somehow make that source publicly
accessible?
That's right, you would need a filepath that is valid on the host
machine.
Is there no (even circuitous) way to capture the output into a real
QT movie file?
There are several. First up I recommend Kineme's Quartz Crystal
Application for ease of use (drag and drop loading plus a command line
tool) and quality of output (it's all rendered on the CPU so every Mac
should give same results). It's a pay-for product but well worth the
$26 to my mind. The demo defaces output so probably no use to you
except for trail purposes.
I suspect I heard about a stock patch in QC4 for output to .mov file
but I'm on Leopard so don't quote me on that. There is an Apple
Developer example plugin for writing still images (jpeg). I used to
use it but can't find ATM and I think it could be used to render
successive files under sequential filenames which you could then
stitch together in a film type app. (Seem to remember QT Pro does it)
Now there is Syphon. Also at a there's pinch screen capture apps (not
recommended for your situation though) and I've found Screenflow to
give best outputs of anything I have tried in that area.

What QC is exporting is still a QC composition but inside a QT file
wrapper. The QT wrapper lets you set a playtime length, which can
be useful if you are playing a QC composition in Keynote.app for
example. If you place a .qtz file on a slide in keynote it will
only play for 30 seconds. If you export as a quicktime movie set to
10 minutes, it will play for ten minutes.
So the exported file is not a QT reference movie in any sense, it
is still executable code being exported, hence the small size (for
a movie).
What other systems may lack is a plugin or patch that your
composition is dependant on, otherwise .qtz files wrapped as .mov
files should play on any system — 10.5, 10.6, 10.7 specific
dependencies not withstanding.
If you post a comp someone here can see if any plugin/virtual
patches are required on the host system from the console/QC log
window.

Noob question about Quartz Composer V4.0. When I click on "Export
as QuickTime Move...", QC exports the composition as a tiny 8k mov
file. It plays, but only on my system, like a 'reference' movie,
where it doesn't actually contain movie data within it. How can I
get QC to generate a movie that contains its data and will play
anywhere? QuickTime Player won't re-export the file or save it as
anything else (all the menu items for that are dimmed out).
