How to pick: Manufacturers publish average bitrates, but variable-rate codecs (N-RAW, R3D NE, ProRes RAW, XAVC HS) routinely run 10–20% hotter on busy scenes. The buffer keeps you from filling a card to its exact limit and losing the last clip.
  • 0% — Math only. Use if you can swap or format mid-shoot with zero consequence (B-roll, screen tests).
  • 5% — Default safety margin. Studio work, controlled subjects, lower-motion scenes.
  • 10% — Documentary, event, run-and-gun. High-motion or detailed scenes that drive variable bitrates above average.
  • 20% — Mission-critical, one-take moments. Weddings, live performances, decisive moments you can't redo.

Cards needed & record time

CardRecord time# for shootStatus
Bitrates come from each manufacturer's official video-recording manual. N-RAW, R3D NE, XAVC, and Cinema RAW Light are variable-bitrate codecs, so real file sizes fluctuate with scene complexity — manufacturers publish average rates, which is what we use. ProRes RAW HQ and ProRes 422 HQ values come from Apple's published specifications. Capacity math uses 1 GB = 1,000 MB to match how cards are sold.

About Camera Data Calculator

What this is. A storage planner for filmmakers and content shooters. Tell it your camera, codec, and runtime — it tells you the data volume and how many cards you need. No signup, no tracking, just the math.

Where the numbers come from. Every Nikon bitrate is extracted directly from Nikon's official online manual table for that body. Sony bitrates are extracted from each body's Help Guide PDF using the same per-body tables Sony publishes. Canon EOS R5 Mark II values are extracted from the Advanced User Guide PDF; the other Canon bodies (R5, R5 C, R3, R6 II, C70) use figures from Canon's official published specifications — the same numbers Canon prints in each model's manual appendix. ProRes values are Apple's published specifications. No guessed numbers.

Cameras covered today. 21 bodies across three manufacturers — Nikon Zr, Z9, Z8, Z6 III, Zf, Z5 II, Z50 II, Z7 II, Z6 II · Sony a1 II, a7S III, a7 IV, a7R V, FX3, FX30 · Canon EOS R5 Mark II, R5, R5 C, R3, R6 Mark II, C70. All bitrate matrices are live in the calculator.

How accurate are the results? Manufacturers report average bitrates for variable-rate codecs. Real shoots fluctuate — high-motion or detailed scenes can run higher. Treat results as planning guidance and always pad your card count. The buffer toggle gives you 5/10/20% breathing room.
