- [Instructor] We've just seen how key frame data
can be edited in the property panel,
but you cannot shift the key frame's timing there.
For that, you need the Dope Sheet,
which offers a very convenient way
to shift the timing of key frames in the timeline.
If your Dope Sheet is not open,
go to the pane popup and select Dope Sheet.
There we go.
Now the rule is, whatever property panels are open,
they'll show up in the Dope Sheet,
assuming there's animation in that property panel.
If there's no animation, it won't show up here.
So if I open up the Transform property panel,
it'll be added to the Dope Sheet.
We're done with the color correct, so let's clear that.
And we'll take a look at the Dope Sheet layout.
Now you can fold up these parameters
to declutter your screen,
and now I am talking to the entire Transform node here.
Clicking on transform one has selected all the key frames.
If I want to deselect, I just come over here and click.
I can move the playhead either in the Dope Sheet
or up here on the timeline.
There are two modes for shifting your key frames,
slip and scale.
A slip, I'll select this.
The rectangle means I've selected all those key frames.
So a slip is just slip the timing forward or backwards.
Notice the blue tick marks up here on the timeline
are shifting with my key frames in the Dope Sheet.
A scale is to grab one of the ends and squeeze it like this.
So now I've slipped and scaled the key frames
for this clip.
And as you can see up here,
the blue tick marks are much closer together.
Okay, I'm going to click down here
in the Dope Sheet to deselect,
and I'm going to undo, undo, undo,
undo, undo, to get 'em all back where they were.
Now here's an interesting behavior you need to know about.
I'm going to unfold my Transform,
and I'm going to select the Translate.
You notice I have key frames right up here,
here, and here for the entire Transform node.
If I take the Translate key frames and shift them,
look what I get.
I get more key frames for the Transform node.
So any key frame that is in a subparameter
gets added to the main node parameter.
So we have many more key frames up here on the timeline now.
I'll deselect and undo that.
If I'd like to slip just the Translate X,
I'll unfold Translate, click the X.
I'll get all the key frames and I can just slide those.
And again, I get increased key frames
for the entire Transform node.
Click here to deselect, undo that.
If I'd like to shift just one key frame,
I can grab, for example, the Translate Y key frame
and shift him forward or backward in time,
and, again, get the added key frame for the Transform node.
We'll undo that.
I can also select a group of them.
For example, I'll just grab all three of these here
and now I can move any number of them that I wish, undo.
Now that we've seen how to create and edit key frames
for both values and timing,
we're ready to take a look at Nuke's powerful curve editor,
which offers even more control over your animation curves.
