My app allows users to manually configure an output resolution for the videos they create.
I notice that above a certain resolution videos can't be saved to the camera roll (it fails silently). Is there any documentation about what the maximum resolution (for different aspect ratios) is that can be saved to the camera roll?
From experimenting on a iPhone 11 Pro it seems to be around 8.5 megapixel frame size, but am hoping there's a way to know without trial and error.
