In this video, we're going to look
at using group grades in the color page. They're a very helpful tool for applying color grades to
multiple clips simultaneously. To add a clip to a
group, right-click on its thumbnail. As we've not yet created any
groups, we'll want to select "Add to new group." I'll call the group "Interview A." It's possible to add
several clips to a group at once. Here, I'll select two clips and add them using the "Add into
current group" menu option. Any time you select
a clip that belongs to a group, you'll see this
chain icon under the thumbnail. The chain icon also appears on the other clips that are
affected by this group grade. On any clip in your
timeline that's not in a group, you'll get
two tabs in the node viewer. Clip and timeline. As this clip is now in a
group, there are two additional tabs. Group "Free" clip and group "Post" clip. Any grades that you want to apply to your entire group should be
placed in one of these tabs. But why are there two
and which one should you use? To answer that question, it's helpful to understand DaVinci
Resolve's order of operations. Operations in the color page
are performed in a specific order. For example, the first node to be
applied to an image will be the leftmost. But even within
that node, if you apply more than one
correction, for example, a primary wheels adjustment
and a curves adjustment, they will be
executed in a very specific order. The corrections made using your primary wheels will influence
the corrections that you make with the curves. And the corrections made in this first node will affect the
corrections you decide to make in the second node. As a result, a colorist will carefully choose the order in
which corrections are made to an image. Now, let's go back to our interview clip. Even though this clip is now in a group, specific corrections can
still be applied to this clip individually in the clip tab or to every clip in the
timeline using the timeline tab. The group preclip and group postclip tabs allow you to choose
whether those group corrections are applied before or after any
clip specific corrections are applied. If a group of clips all required the same primary correction,
I might choose to perform that correction preclip. That means I can
make secondary corrections at the clip level and
those secondary corrections will be executed,
rightfully so, after the primary corrections
performed in the preclip grade. Alternatively, if I'm using a group grade to apply a
creative look to a collection of shots, I would probably choose to
perform that in the group postclip tab. This allows me to use group preclip to apply primary
corrections and clip to shot match each clip individually so
they will work with my creative look. In the instance of
this project, I'd like to use groups to simplify the
process of grading the interview. As the interview is constructed
from several takes, using remote grades as discussed in the previous
lesson won't work as effectively. I'd have to create 10
grades, one for each take and angle. So I'll continue
grouping the shots into two groups, one for the
A camera and one for the B. It's tedious doing
this though in this view. Instead, I'm going
to switch to the light box. By default, the light box will
show me every shot in the timeline. I can take advantage of
the metadata I've already entered for this project to make
the selection process even quicker. I'll make my own Smart Bin. I'm going to call it Interviews No Group. The first criteria is that the
media pool scene contains interview. The next criteria is
that the clip has no group. This will help me to filter
out the shots I've already grouped. Hit plus, then set it up. Timeline Properties Group Is And then leave it blank. Now I'm only going to see the
interview clips that have yet to add a group. Now this edit is pretty simple. There's not that many shots. But you can imagine how helpful the No
Group filter would be on a very large edit. Also, if the camera letters
were specified in my clip metadata, this would have been even easier
because I could have filtered by camera angle. I don't have that set up, so
I'll just do this final bit by hand. Holding Command or Control, I can
select all the A camera clips one at a time. Now right click and
add them to the A camera group. Finally, let's add those B
cam shots to a group of their own. Fantastic! Now we're done. Don't forget to remove
your filter by hitting all clips. We can now close the light box. In the color page, I can grade the
entire interview with now just two grades. I'll make an adjustment to the A camera. As this is a primary
correction, going to choose to do it pre-clip. I'll give the gamma a small push
of blue and add a little more contrast. Thus far, we've used group
grades for technical operations. They are also great
for applying creative grades. I'm going to add all the dance shots
to a group so I can uniformly apply a creative look to them. As all the dance shots are in the second video track, I can
make selecting them easier by disabling track 1. You can do that from the color page by opening the timeline
viewer and clicking on V1. Now only track 2 clips are visible. I'll select the first clip in the dance sequence, hold down on
shift, and click on the last clip. Now that they're selected, I
can add them to a group called dance. As this is a creative look, I'm
going to apply it to the post clip tab. I'll turn everything black and white with the monochrome
checkbox and RGB mixer, reduce the gamma and contrast. Make a new node
and then add a sepia tone. This look is now being applied
to every shot in the dance sequence. I can see though that some clips are
too bright to work properly with this look. I can better match these shots
by adding adjustments at the clip level. I'll reduce the brightness of
this clip, the reduction in gamma. Now it better matches the other shots in this group, but as
that correction was applied at the clip level,
it only affects this clip. I hope you enjoyed this in-depth
look at using groups to create grades. And as you can
see, groups are very useful for a variety of
technical and creative tasks that you might perform when grading. If you enjoyed the

complete DaVinci Resolve course. It will teach you
everything you need to know to edit, color, and
mix audio in DaVinci Resolve. Like the content on our channel, it's
designed to be comprehensive yet efficient. We think it will
be particularly helpful to editors with
experience in other NLEs like Premiere who are
looking to expand their skill set. But if you're a beginner, we
think you'll love the course too. We just won't be spending lots of time on concepts that
editors are already familiar with. We're going to get
straight to the good stuff. Well, more on all of that soon. Thanks so much for watching.
