About DataCalc
DataCalc by CONFORM.TOOLS is a free suite of professional video production calculators. Whether you need to estimate how much storage a shoot day requires, figure out how long a file transfer will take, or convert between video duration and file size, DataCalc has you covered.
Our tools support cameras from ARRI, RED, Blackmagic, Sony, Canon, and more. Calculate with industry-standard codecs including ProRes, ARRIRAW, REDCODE, DNxHD, and H.264/H.265. The Timecode Calculator lets you add, subtract, multiply, and divide timecode at any frame rate.
Every calculation can be logged and shared with your team. DataCalc works offline as an installable PWA, so your tools are always at your fingertips — on set, in the edit bay, or anywhere in between.
DataCalc is built by CONFORM.TOOLS, makers of professional conform and post-production software. Check out our other tools for editors, assistant editors, and finishing artists.
Frequently Asked Questions
How much space does video take up?
Video file sizes depend on resolution, codec, bitrate, and duration. For example, 1 hour of UHD ProRes 422 HQ is roughly 318 GB, while 1 hour of H.264 at 50 Mbps is about 22.5 GB. Use the Duration ↔︎ File Size or Camera ↔︎ File Size calculators to estimate exact file sizes for any format.
How do I calculate video file size?
Multiply the bitrate by the duration: File Size = Bitrate × Duration ÷ 8 (divide by 8 to convert bits to bytes). For professional camera codecs like ProRes, ARRIRAW, or REDCODE, the Camera ↔︎ File Size calculator includes real data rates for ARRI, RED, Blackmagic, Sony, Canon, and more.
How much storage do I need for video production?
Storage needs vary with camera, codec, resolution, and shoot duration — a single day of RAW cinema camera footage can generate multiple terabytes before backups. The Dailies Calculator and Camera ↔︎ File Size calculator help you plan storage for original camera files, proxies, and redundant copies.
Are these calculators free?
Yes. Every DataCalc tool is free to use, works in any modern browser, and can be installed as an offline-capable app. DataCalc is built and maintained by CONFORM.TOOLS, makers of professional post-production software.
How long can I record on my camera card?
Recording time depends on your camera, codec, resolution, frame rate, and card capacity. As a rule of thumb, divide card capacity by the codec data rate — the Camera ↔︎ File Size calculator does this for you with data rates for popular cinema and mirrorless cameras.
