Frequently Asked Questions
What speed class do I need for 4K video?
Aim for at least V30 (video speed class) or U3 for standard 4K; choose V60 or V90 for 4K/60fps, higher-bitrate codecs or multi-stream recording to ensure stable sustained write performance.
Can I play 4K files directly from a microSD card?
Yes — many media players (and some TVs) can play 4K files directly from microSD cards or USB drives. Ensure the player supports the file’s codec (H.265/HEVC is common for 4K) and the card is formatted with a compatible filesystem like exFAT for large files.
How should I protect my footage from card failure?
Use multiple cards during shoots, format cards in-camera before use, back up footage immediately to a separate drive, and consider higher-end cards with better endurance or a camera that supports dual recording to two cards simultaneously.
