Video storage FAQ

Plan media before the shoot, not during the panic

Bitrate, codec, frame rate, and backup strategy can change a shoot budget fast. Use the calculator as a planning tool before choosing cards and drives.

How do you calculate video storage from bitrate?

Bitrate in megabits per second is multiplied by recording seconds, then divided by 8 to convert bits to bytes. GearAtlas then adds shoot days and backup copies.

Why do high-bitrate formats need faster cards?

The important number is sustained write speed. High-bitrate All-I, RAW, 6K, and 8K formats may require V90 SD, CFexpress, or external SSD recording.

Is H.265 always better because files are smaller?

Not always. H.265 is efficient but can be harder to edit. ProRes and All-I files are larger but often smoother in post-production.

How many backups should I plan?

For paid work, plan at least two backup copies in addition to original media. Critical shoots often use a 3-2-1 backup strategy.

Are camera presets exact?

They are planning presets for common recording modes. Always confirm the exact bitrate and media requirements in the camera manual before a paid shoot.
