I don't remember the default video settings. But their are a lot of YouTube videos showing recommended settings for the mavic that you may want to watch.
As for FPS I record in 60FPS at 1080P for the ability to slow down video post editing, or 30FPS at 2.7K to 4K.
One warning, I did try the 96FPS at 1080P and most editing software and video players think this is some sort of super slow motion and plays it like super slow motion. So that video I had to speed up just to look a little normal.
So unless your sure your editing software support a 96FPS profile I wouldn't use it. It's seems to be a new FPS rate and not all editing software support it yet.
