I am working on a Frame-by-Frame animation program, where users can design each frame of an animation. In the end, they can view all of their frames animating.

I want to let the users save the animation as a video file. I need a way to compile all of the pictures (frames) into one video file. How would I go about doing this?

This is called encoding and the best development kit to use is ffmpeg. I am also learning how to do this at the moment.
