While UHS 1 SD cards can be used for 4K video recording, they may not be the best choice. This is because the minimum write speed of 10 MB/s may not be sufficient to handle the high data rate of 4K video, which can be up to 100 MB/s or more. This can result in dropped frames, stuttering, or even the camera shutting down due to buffer overflow.
Can you record 4K on UHS 1 SD cards?
Yes, it is technically possible to record 4K video on UHS 1 SD cards. However, as mentioned earlier, the minimum write speed of 10 MB/s may not be sufficient to handle the high data rate of 4K video. This means that you may experience dropped frames, stuttering, or other issues during recording. Additionally, the camera or device may not be able to sustain 4K recording for an extended period, and you may need to stop and start recording frequently to avoid buffer overflow.
That being said, some cameras and devices may be able to record 4K video on UHS 1 SD cards without issues. This is often the case with lower-end cameras or devices that have lower 4K video data rates. However, if you’re planning to record high-quality 4K video, it’s generally recommended to use a faster SD card, such as UHS 3 or V30, to ensure smooth and reliable recording.
