Mevo has three options to choose from for outgoing frame rates: 25fps, 29.97fps, and 30fps.
This feature is currently only available in version 1.6.10 Beta of the Mevo app. Learn more here.
To change your frame rate, open the options menu and select Advanced Settings. The sixth option down is Frame Rate. Tap the desired frame rate you wish to use; your selection will turn blue.
