Hi
Keyframe Control of a Codec allows parameter changes to:
i) how many frames between each keyframe, and, depending on the particular codec compression software,
ii) how the data-compression in the keyframe relates to the compressed data allocated to each inter-frame.MJPEG A and B don’t have any keyframe control because, as I said, every frame is a keyframe.
