FAQ

Sustained write speed determines whether a card can keep up during real, continuous recording, which matters most for high-resolution video, continuous burst shooting, and slow-motion capture. Some cameras require a specific VPG rating to unlock certain recording modes, so using an uncertified or under-rated card can result in dropped frames or the camera refusing to record. Because some cards use the VPG logo without being properly certified, it's worth confirming a card's certification through official channels before relying on it for demanding work.
