  • Keyframe - a reference frame typically used as the beginning or end of an animation sequence
  • I-frame (intra-coded frame) - a complete frame which can be independently decoded.
  • P-frame (predicted frame) - an intermediate frame which requires the previous frame to decode.
  • B-frame (bidirectional frame) - an intermediate frame which requires the previous and next (non-B) frames to decode.
