This is really a feature request: I would love it if the Video Pro app would make it onto the Xperia 1/5iii.

Currently only the basic app is available, or you would need to use the Cinema Pro app. 

With the basic app I often face banding with indoor led lighting on my 5iii. The frequency of the electricity here is 50Hz, and the app does not seem to automatically adjust the shutter speed to prevent banding when shooting video.
