I want to give you guys a quick breakdown of how Keyframes can be utilized in Resolve 15's Fusion. They are pretty simple once you know where to look, but they can be a bit tricky to uncover at first.
So with this shot I've got an over-head clip of the ocean, and I've comp'd in a layer of cloud that I want to 'fly' through as we get closer to the ground.
So the easiest way to accomplish this is to just fade out the layer as we play through the timeline. So as you can see I've got my shot set up like this: MedaiIn1 > PlanerTracker(tracked the cloud layer onto the coast clip) > Merge1.
(If you'd like to know how I tracked the shot, take a look at THIS tutorial!)
Also going into the Merge1 is the cloud node and the PlanerTransform node.
So with the Merge1 Node selected, look over at our Inspector tab and you'll see some options for adjusting the layer. What we're interested in is the blend slider. It's basically the layer's opacity. At 1.0, it's at full strength, 0 means it's invisible.
So our first keyframe I want to have at the start of the clip, so I go to the Blend slider, and just to the left of the slider is a little diamond, or keyframe. Clicking it will turn it red. This indicates there is now a keyframe for blend there.
Now I go to where I want the clouds to be completely gone and I'll move the blend slider all the way to 0. Notice that I don't have to create a new keyframe because once I set the first one, any adjustments to that property will automatically add a keyframe.
You can now look at your timeline and you'll see a small white notch. This indicates a keyframe.
Cool, right? But what if it just doesn't feel as smooth as it should? Let's explore how we can adjust the keyframes to get the right type of motion we're looking for.
Up in the right corner is our Keyframes tab, which opens up a new timeline at the bottom. What this new timeline shows is all the nodes stacked together with all the keyframes available.
*NOTE* This is not like photoshop, these aren't layers. They just show each keyframe timeline. The order doesn't matter.
So in our list there is an arrow next to the Merge1 node. If we twirl that down we see the animation info for our blend. The white lines indicate the keyframe positions and will adjust the start and stop position of the animation.
So let's say we want the clouds to fade out a little slower, not just in a linear fashion. Up next to the Keyframes tab is a button called Spline. This opens up your animation timeline with a host of new tools.
As you can see, our animation goes off into neverland, so to fix this hit thie little button here, which is called Zoom to Fit. Now we can see the whole animation.
Now, just by clicking on the line we can add new keyframes and change the way it animates. But what we're going to do is select the first keyframe and hit 'F'.
What this does is essentially flatten out the control points, creating an ease in and ease out. Now our fade is a little cleaner!
There are a bunch more tools, but I just wanted to get you familiar with where keyframes live and hopefully make them a little less scary. Now get in there and experiment!
