Frequently Asked Questions

How much storage does 4K video use?
4K video at standard 8-bit compression (H.264/H.265) uses about 40-50 GB per hour. 4K at 10-bit in ProRes or RAW formats uses 100-120 GB per hour. The difference is huge, so always check which codec you are shooting in. An 8-hour shoot day in 4K 8-bit needs about 360 GB, while the same day in 4K ProRes needs close to 900 GB.
How many batteries should I bring for a full day shoot?
For mirrorless cameras, plan on about 1.5 hours per battery when shooting video, plus one spare. A full 8-hour day needs 6-7 batteries. DSLRs last longer at about 2.5 hours per battery. Cinema cameras burn through batteries fastest at about 1 hour each but use larger V-mount or Gold-mount batteries. Always bring at least one extra beyond your calculated need.
What SD card speed do I need for 4K video?
For 4K 8-bit video, a V30 (30 MB/s write speed) card is sufficient. For 4K 10-bit or higher, you need at least V60 or V90 cards. Cinema cameras often require CFexpress cards for their higher sustained write speeds. Using a card that is too slow will cause dropped frames or recording errors mid-shoot. Always check your camera's minimum card speed requirement.
