Grading a pre-recorded multicamera shoot

PostSun Sep 13, 2020 7:55 pm

So, I've recently been doing some 3 camera shoots and doing a live edit using the blackmagic atem mini and recording at a high bitrate in OBS.
This of course gives me a file (an mp4 in this case) with all my cuts prebaked in.

At the moment I'm using a pocket 4K and 2 Canon XF305s which look quite different to one another, even at the same settings. I can get them to look closer by eye before shooting, but this takes a little bit of time and isn't perfect. Also all 3 cameras shoot quite a neutral style and so doing some grading anyway would be great.

My question is, is there an easy way to import this footage into Resolve and then edit the grade on each camera individually?
I could do scene cut detection, do an initial grade for each angle and then do stills but then I'd have to apply these manually to each cut. Is there a way to get resolve to automatically group all the shots from the same angle and apply a grade?

As they all come from the same clip, no there isn't.

You may want to take a look at the ATEM Mini Pro ISO, though.

try:
- in media pool flag all clips from each camera (i use Acam = yellow / Bcam = blue / Ccam = green)
- in color page filter by flags
- make a group for each set of flagged clips
- add camera offset in pre-group if not useing luts (postgroup if useing luts)

Hey,

Ditto, like Dermot told you...

So it's not "automatically" since you cut (with scene cut detection for ex.) in a single file, but making groups can be fast.

Just bought one!

My final solution for this, just in case it helps anyone else, was because I was recording to each camera individually as well anyway, I graded them all in Resolve and then exported out LUTS of each grade.

I then brought it all into Premiere (because I'm more familiar with it), and made a multicam sequence of each angle, plus the original multi-cam recording. Applied all the LUTs to the angles. And then made sure the multi-cam recording was selected in the mcam sequence and ran a scene edit detection in Premiere, which gave me all my cuts.
I then just went through and switched out each angle as necessary.


It worked, but quite time consuming, and so I'm hoping that the ISO will speed up my work flow.
