Bi-directional (B) frames are encoded based on an interpolation from I- and P-frames that come before and after them. B-frames require little space, but can take longer to decompress because they re reliant on frames that may be reliant on other frames. A Group of Pictures (GOP) can begin with a B-frame, but can t end with one.
