ProRes

Apple's professional video codec for editing.

ProRes is Apple's high-bitrate intra-frame video codec, designed for editing rather than delivery. Each frame is independently compressed (no GOPs), so scrubbing and color grading are fast. Hardware-encoded on iPhone Pro since the 13 Pro and on every Apple Silicon Mac. File sizes are large — 4K ProRes 422 HQ runs ~750 Mbps.
