Ok well thanks for all of that information. Unfortunately I didn’t shoot it, I entrusted that job to someone else. Like you say, it is done now so I’ve just got to work with what I’ve got.
I did a test reconverting some footage and 422 does look better that LT and weirdly looks better than HQ which seems strange.
I am getting to grips with keying the background out using the manual controls but it does look a bit raggedy in places which is s shame. Some mistakes here that I won’t make again!
