How It Works

Video file size is determined by three factors: resolution (pixel count), frame rate (frames per second), and codec (compression method). H.264 and H.265 use lossy compression — H.265 is ~40% more efficient at the same quality. ProRes is a production codec with minimal compression — much larger files but easier to edit. RAW records uncompressed sensor data — enormous files but maximum flexibility in post. For most creators: H.265 at 4K/24fps is an excellent balance of quality and size. For professional workflows: shoot ProRes or RAW, then transcode to H.265 for delivery. Higher frame rates multiply file sizes linearly — 60fps is 2.5x the data of 24fps.
