A frame is a still image. Video is made up of many frames per second to create the illusion of movement.
Types
Digital video compression techniques involve compression of frames:
- I-frame
- A full 'Intra-coded picture'
- P-frame
- 'Predicted' from previous frame(s)'s picture
- B-frame
- 'Bi-predictive' or 'Bidirectional' calculated from surrounding frames's pictures. Can painlessly be skipped.
