Many mobile devices support 4K recording. However, not all devices of 4K recording feature can support 4K editing in KineMaster. The difference comes from the fact that 4K editing needs one 4K encoder and at least one 4K decoder at the same time, while 4K recording needs just one 4K encoder.

When you import 4K videos to KineMaster on the devices which can't support 4K editing, KineMaster re-encodes 4K videos to 1440p or 1080p videos for editing.
