First of all some tips about editing, i know you said you didn't spend much time on it but this are really the basics:
- 57sec intro is to long
- don't show your fails
- don't show unneccesary footages, like the crossfire bounce you fail the landing and die and than you see you respawn again, don't show the respawn (prefer you won't show a fail bounce but ok:P)
Than the quality. Now i don't expect much from consoles when its a matter of quality, but when you see the pixels you go to far. Now i play on PC so i don't know how the recording works on consoles, but take this for example:

Its not great compared to PC but atleast its smooth and you don't see the pixels. Thats what im expecting from the quality from console videos.
And may i ask how much you spend on that capture card? I think you got ripped off.
