2. The timeline stretches
3. freeze frame
4. Slow motion curve

The main content of this paper is some practical operations in the project .

One . Video clip

1. Shortcut key

cmd+shift+d, The synthesis will be cut into two segments , Disconnect from the current frame , In the upper and lower lines .

option/alt+【 Is to cut out the previous part of the current frame
option/alt+ 】 Is to cut out the next part of the current frame

2. Composition settings

Right click in the blank space of the timeline panel , Select compositing settings , You can set the length of the timeline .
Set the number of start frames , Frame rate, etc .

Two . The timeline stretches

1. Used to quickly adjust the speed of synthesis
2. Select composite , The right choice - Time - Time scaling
3. Calculated as a percentage ,100% Is the original speed ,50% Namely 2 Double speed

3、 ... and . freeze frame

1. You can stop the video at a key frame . For example, you want to make the animation still at the last frame after playing .
2. Select composite , The right choice - Freeze at the last frame , Then the animation will move to the last frame , Still in the last picture .
You can also choose to freeze frames , It will rest on the current indicated frame .

Four . Slow motion curve

1. Select a key frame , Press f9 You can make the key frame slow automatically .

2. You can also select keys , Right click - Keyframe assist - Choose different curve types

3. If you want to remove the jog curve, choose keyframe interpolation , If you change to linear interpolation, there will be no slow motion .

4. How to adjust the curve
1. Select a layer , Select the small curve icon of the timeline panel , Call up the curve interface .
2. Hold down alt/option+ The middle mouse button can adjust the width and height of the curve panel .
3. If the animation has been done , I just want to change the position as a whole , You can use the curve panel to adjust .
After calling up the curve , Select this figure , Select the attribute that needs to be changed , Then select the red box button to adjust the attributes separately , Just select the anchor point change position by frame .
