Hey JHave,
I'm comment inline:
grab video from camera in real-time
no problem in Gem (DV video in, very very fast) (on OSX)
periodically save it to a file(s)
is pix_write working in OSX yet? Are you talking about saving a chunk of video, or individual frames? I never tried using pix_multiimage to load an array of images files saved with pix_write the performance may not be all that great.
chroma key it as it is displayed
Gem, no problem.
concurrently display previously-saved video(s) behind the current
real-time
video
no problem in Gem
apply diverse effects in real-time to the previously-saved video files
that
have been loaded in
define "effects" Gem has pix_ filters, and you can do a heck of a lot with openGL transformations for "effects".
vary the amount of these effects according to gradiant input from a motion sensor
Whats the HW interface for the sensor?
I would say in conlusion that I can't think of a good reason for using Jitter for this project. Perhaps to be able to save QT movies rather than individual frames...
Whats the timeline of the project? Gem is always changing!
Ben
