Removing a key frame doesn’t remove the frame itself, it only removes the
reference to that frame as a key frame.
Not all compression schemes will follow the key file, and those that do, such
as Cinepak, may still insert key frames wherever they determine there is a
need. This is out of the control of Video Editor and in the hands of the
compression scheme itself. Therefore, you may sometimes find that removing
key frames does not change your video appreciably in your next analysis.
