Im thinking of shooting video in a Club, we are holding Go Go Girl Auditions, should I film in raw or should I just film with the cannons native software?
Besides all photographic considerations, I would start with a pragmatic question: are you willing / able to shovel really huge amounts of data? One RAW frame 1472x626 is about 1.7 MB. If you shoot 24 or 25 fps, you end up with 2.5 GIGABYTE PER MINUTE. If you shoot e. g. 30 minutes footage (what I would consider not much given your setting), you have 75 GB sitting on your CF cards and (later) on your disk.
And at least during pink-dot-removal, this doubles for a short while: 150 GB.
And after you develop the RAWs into MJPG, you might have approx. 1/5 of the size, so about 15 GB...
And other figure: for me, rawtherapee and all four cores at 2.9 GHz ("Turbo Mode"

) need approx. 2 seconds / frame for applying some color correction, tone mapping and noise removal on a 1280x720 image. So my machine would need 50 minutes to convert one minute of 25 fps RAW material to JPG. Depending on your computer, your pace my vary, of course.
All I want to say is: RAW is nice but not really handy...
