Any advice on matching gh2 and 5d footage? Are the in camera settings to do this?

I've not used the 5d, but I will suggest that the lenses you choose would play a part in how well the footage matched, not just the cameras themselves, IMO.

There are a LOT of people running this combo, so I'm sure someone will chime in.

Having owned both (I no longer have the 5D) I would start by putting the 5D Picture Style to Standard
(Standard, Portrait, Landscape, Neutral, Faithful, Monochrome, User Def. 1-3)
And on the GH2 setting the Color tone setting to Standard.
Although the 5D style of Landscape is similar to the GH2 Color tone setting of Vivid.
And of course at the same pixel setting.
I am sure the folks using both will have more details.

I'm using Canon L primes on both cameras
