120Fps

Some raws are 120 fps, which provides a way of storing hybrid? video with progressive? frames without losing any information. 120 is the lowest common multiple of 24 and 30, therefore videos with 24 fps sections and 30 fps sections can be stored in a constant frame rate file at 120 fps, by adding duplicate frames, 4 extra frames for 24 fps sections, and 3 for 30 fps sections.

This is, however a HACK to get around the constant frame rate limitation of Avi?. Using Mkv? or Mp4?, both of which support full VFR? (variable frame rate), 120 fps files are no longer necessary.
