delta frame

In interframe video coding, a delta frame is a "difference" frame that provides an incremental change from the previous frame. Delta frames can be P-frames or B-frames. P-frames (predictive frames) contain only the changes from the previous frame, whereas B-frames (bi-directional frames) are P-frames with data about the next frame. See interframe coding.

264, for example, you can set the profile and level, but there are no controls for entropy encoding (CABAC/CAVLC); the B-frame interval is called Re-order Delay, which is confusing; and you can't set the number of reference frames.
With proven leadership in quality and design, the Magnitude Encoder enhances MPEG-2 signals by implementing differentiating technologies such as statistical multiplexing, B-frame insertion and automatic telecine detection and compensation.
A B-frame can be highly compressed, but its decoding requires references to both backward and forward I-frame or P-frames.
To test this, I encoded the test file twice in Sorenson Squeeze, once with no B-frames, next with a B-frame setting of 3, Squeeze's maximum.
