Need help Color Correcting a7sii footage

[pickett22]

Hi, I have been practicing with my a7sii and didn't get the custom white balance set correctly before shooting in the Cine4 mode. I have tried everything in premiere pro to get it close to natural looking and it's just not working. My primary was Canon 6D and the A7SII on a tripod right beside it to compare in post, and a GoPro5 also.

I have tried everything and I just can't get the color right. I have since practiced in multiple lighting conditions and sometimes the custom WB (using gray card) looks great and sometimes the Auto WB looks better.

If anyone has time could you look at these four 10 second clips to see if anything can be done to get the color corrected as close to the True color video and photo samples. I'll make a donation to you if you'd like.

 

CONDITIONS:
Late afternoon, sun behind waterfall, clouds overhead with a little sun hitting clouds - they rushed the start time and didn't have time to get custom WB.
CAMERA SETTINGS:
Canon 6D - on lowest contrast, WB set to 6500k, light meter at 0.
A7SII        - Cine4, SG3C color, WB set to 6500k, Zebra just a tough showing on the brides dress at cleavage.
GoPro5     - ProTune, WB set to 6500k, Auto iris

Thanks for any help you can give.

The top grade is the Sony (0:6.07) 'cause that's what I shoot and spent maybe a minute colorizing to what I like my grades to be. Could be tricky with all of the different hardware on the shoot but things ARE doable.

 

UPDATE: I ignored matching your 'similar' TRUE COLOR SAMPLE because that's a different shoot with a different dress and complexions.

 

The 'trifecta' is all three clips in the same timeline with the SAME CORRECTION applied across all 3 as a single adjustment layer. I edit this way to adjust the other two cams to my favorite look and can readily tell which direction each grade needs to be pushed.

 

Panel 2 has too much magenta in the brides gown and the details are lost in the grooms jacket. Panel 3 is going to require the greatest correction unless the maids gowns were actually turquoise. Boosting global saturation 25% in panel 1 to match maids dresses in panel 2 maintains whiteness and details of bride & groom but LOWERING saturation in panel 2 by 41% gets the brides gown white but the details clip and remain lost.

 

In panel 3 lowering highlights -25% and global saturation -15% gets you seriously close to where you need to be. (I'm assuming you didn't shoot in a LOG profile since it wasn't mentioned. Should be easier to match if you did.)

Timed out for editing my post above but you should get the idea. The point is I chose to match everything to panel 1. Spent 5 minutes getting it this far so you should get better results the longer you work it but keep an eye on the GoPro footage.

 

- A - Sony footage and a bit of grading to it.

- B - Same grade across all video on an adjustment layer. Panel 2 has richer colors but at expense of white (?) bridal gown.

- C - Correcting footage to match panel 1 with a bit of funkiness going on in GoPro footage. (I had to muck with the blue hue and saturation vectors and also the hue, saturation, and luminosity vectors of the cyan channel to get the GoPro footage where it is and STILL needs fiddling with but five minutes was my limit. ALL your footage was way too cool from where I sit and the conch pic gown appears lavender.)
