Re: Arbitrarily Changing Frame Rate Throughout a Movie

I think what Dr. Lowney is looking for is a simple way from the user end to set arbitrary durations for individual frames... FCP4 just handles interpolating between different timings (framerates/durations), and ultimately will just output with a common duration for all frames.


I've wondered the same myself... I know I can get at it via QT APIs, but short of using SMIL to display frames individually (and I'm not sure of the accuracy of SMIL for this, as it would have to handle preloading/buffering, etc) I don't know of another simple user tool for this purpose.

Simple example:

You do a timelapse capture from a security camera... during the day you want to preserve all the original frames at their original rate -- say 2fps. But during stretches of the evening, you only want to preserve unique frames, and stretch the frame duration to cover the original timing, while using far fewer frames.

At least this is what I want... Dr. Lowney, please correct me if I just hijacked your thread :)
