Writing the minor changes between frames takes up less space than writing the entire frame each time. Added saving and loading filter sets: Filters. Use the same flip process to make text photographed backward (e.g., in a mirror, through glass, or using a reverse-facing camera) and face the right way. An “I-Frame” is a complete frame, whereas P/B frames contain only the minor changes. Added Speed: Forward Only and Speed: Forward & Reverse filters. This is sometimes called Long-GOP or IPB encoding.
