Frequently Asked Questions
Why is my card's actual capacity less than advertised?
Manufacturers use decimal gigabytes (1 GB = 1,000 MB) while computers and this calculator use binary gibibytes (1 GB = 1,024 MB). A 64 GB card holds about 59.6 gibibytes of actual data.
Why does RAW vs. JPEG matter so much for capacity?
A compressed RAW file from a 24 MP camera is about 24 MB, while a fine JPEG is roughly 12 MB and a basic JPEG about 6 MB. The difference multiplies across hundreds or thousands of shots.
Is ProRes worth the huge storage cost?
ProRes 422 at ~590 Mbps gives editors maximum flexibility and color depth for color grading. For broadcast, cinema, or commercial work the quality trade-off justifies the storage cost. For YouTube or personal use, H.264 or HEVC at 4K delivers excellent results at a fraction of the space.
Should I use one large card or several smaller ones?
Multiple smaller cards reduce the risk of losing all footage from a single card failure. However, many professionals prefer large cards to avoid swapping during critical moments. The ideal approach is dual-slot recording to two different cards simultaneously.
