Now try recording the same scene and duration in 720p and look at the file size - that's the real mind boggler

I haven't been able to find out if this camera is giving you 8 or 10 bits out, but assuming 8 since they don't say, your uncompressed two minutes would be about 72 Giga bits, or 9 Giga Bytes.
Long GOP gets you the best picture in the least bits, but it takes some extra effort to edit.

You also have to really try very hard to intentionally break the XDCAM EX mpeg2 codec in acquisition. Generational edits and heavy post will produce quantisation banding and build on the inherent mosquito noise though of course, so transcode to something more suitable.
