I‑frames, P‑frames, B‑frames
An I‑frame are fully-specified pictures. The following frames (P‑frames and B‑frames) hold only part of the image information (→ the difference compared to the I-frame), so they need less space to store than an I‑frame, and thus improve video compression rates. See “Video compression picture types” for details.
