So if I shoot my clips under 20 seconds I can upload them on all the sites accepting stock footage? I will try to make my first with the new firmware upgrade for 5D mark II.
Microstock = "Masters of the 19 second video"

I was going to try an animation and now I know what I should plan for, frames/frame rate = 19 seconds.
At 28 fps a 2gb card that holds about 500 images, will shoot a 17.8 second animation. COOL!
Now I need to figure out the interval so the motion is smooth.
