I intend to use footage from both a Mavic Air and a GoPro hero5 session. Any tips to ensure footage from both looks similar in terms of colour profile etc?
I'd advise using the Cinelike profile on the MA and the 'Flat' profile on the Hero 5 session (you need to turn on protune to select this'. That way you'll have both fairly flat profiles and you can get them to match better in post. I'd also change the field of view on the GoPro to 'linear', otherwise you'll have the fish eye distorted look, which wouldn't match well with the MA.
