First flight... Bad video! :(

[Clunk]

Just done my first flight with default settings on the camera.
Can anybody tell me why the footage 'rolls' as it gets darker? HERE!
Is it just a setting that needs a tweak, or is there a problem with the camera?
I hope it's visible on the upload.

(Excuse the video... It's Facebook's poor video compression!)

Try loading on a laptop, with a SDcard reader, cleaned up my videos

Doh!!!
I've just realised the files on my phone are not full resolution/quality.
The 'real' files on the memory card are perfect!
