Understanding ProRes RAW Data Rates

ProRes RAW is a revolutionary codec from Apple that brings the performance of ProRes to raw video. Unlike traditional video formats, ProRes RAW is a Variable Bit Rate (VBR) codec. This means that the actual data rate changes depending on the complexity of the visual scene. High-detail images with lots of motion will result in larger file sizes than static, simple shots.

Key Factors Influencing Storage:

  • Resolution: The total pixel count (e.g., 4K vs 8K) is the primary driver of data volume. 8K contains four times the pixels of 4K.
  • Frame Rate: Higher frame rates (like 60fps or 120fps) increase storage linearly. 60fps uses roughly 2.5x the data of 24fps.
  • ProRes RAW Variety: ProRes RAW HQ captures more detail and has a higher target data rate (roughly 1.5x) compared to standard ProRes RAW.

Realistic Storage Examples:

Format Estimated Mbps GB per Hour
4K 24p (Standard) ~420 – 580 Mbps ~230 GB
4K 60p (HQ) ~1600 – 2200 Mbps ~850 GB
6K 24p (HQ) ~1200 – 1500 Mbps ~600 GB
