Ok, this isn't like a technical post or anything, just a comment on a REALLY
BAD blue/green screen I saw in a TV ad lately. Has anyone here seen and (I
think) Larry Korn ads? In one of his ads he is composited over this shot of
someones foot as the person was walking (as he talked about how he would take
anyones frivolous lawsuit). The person was walking toward him, and it looked
like he was about to be kicked... I guess that the production house noticed
but decided the couldn't afford to reshoot or recomposite, so they cute right
there... It still looked like he was going to get a boot to the head, though
(which, I hate to say would be nice. TV lawyers should be shot ;).

Has anybody else seen any really bad compositing jobs? Like, microphone booms
composited into shots of some superhero flying through the air? ;)

by the way, could someone tell me what the difference between montage and
collage is?

time vs. area.

Ahhh. So montage is just a bunch of individual images faded into each other
over time, rather than being on the screen at the same time? 
Hmmm... thanks :)

Has anyone ever seen a film called "Powaqqatsi" ? It had some pretty
impressive video techniques in it -- they were pretty basic (mirroring,
montage, collage) but very artistic. It is definitely the most artistic thing
I have ever seen layed down on film, even if I am still not exactly sure of
the point it had (if any) <grin> 
Its probably worth renting (its classed as a documentary, probably because
no-one could come up with a better classification for it). Strange to say,
the video almost looked like it was, for lack of a better word, dancing...
which could make sense since the whole bloody thing was set to Philip Glass
music. If you rent it, don't bother watching the whole thing. You will fall
asleep. (sorry if this seems disjointed... i got about 17 messages while
trying to write it).

Actually, I'm impressed you figured out my response... ;)

Yes, montage is a series of images, rather than several images at once
(parallel).

In other words, a montage is a set of audio and/or video images in a 
pre-determined order, while a collage is more of an inanimate media 
image.  Is that correct, or did I go wrong anywhere?

Collage is not neccesarily "inanimate." Especially if you are working on a
digital system where it is very easy to layer many "live" (that is, moving)
images.

Montage in printing is a group of *superimposed* images. In motion pictures
(and apparently now with computers) it is a sequence of images. But
you can also superimpose images with computers, so wouldn't that also be
montage?

I think you have to regard the computer as just an intermediary tool that is
producing either video or photography, and you have to classify stuff on the
end product (be it still or moving) whether it came off an AVID Dt-video
station, or a kodak camera.
