Let’s begin!

Let’s start!

In the Timeline panel, the layers of objects placed in the composition are displayed separately, so you can edit them while viewing the Composition panel. In addition, 3D, Shy, Motion blur and other switches are available, so you can adapt a variety of effects to layers.

Display a timeline panel

The Timeline panel is where you can edit and it is created automatically when you create a composition.

Each time you create a composition, a tab is created at the top of the timeline panel, so you can change the view of the composition and edit it by switching the tab.

Description of the various switches

The switches shown in the Timeline panel have many items to make editing easier.If you view all of them, it may be difficult to see when editing so these switches help us to display or hide the functions if necessary.

Display/Hide switches

If the switches are hidden in the Timeline panel, you can use the [Layer Switches] at the bottom left of the Timeline panel to display them!

There are three layer switches. From left to right, they are Layer Switches, Transfer Controls and In/Out/Duration/Stretch.

Switches for the A/V function

The switches for displaying, hiding, and locking video and audio are located at the leftmost position.

From left to right, we have 4 switches consisting of Show/hide layers, Audio On/Off, Show only the specified layer and Lock layer.

① Show or hide layers. When hidden, it disappears from the composition panel and will not be rendered.

② Switch to turn on or off the sound of the layer.For layers that do not contain audio, this switch is disabled.

③Select this switch to display only that layer.The switch can also turn on multiple layers at the same time.

④Select this switch to lock the contents of that layer so that they cannot be changed.You can also lock multiple layers at the same time.

Switches in Layer Switches Pane

Layer Switches Pane consists of switches related to layer . Let’s take a closer look at each one!

①You can temporarily hide the layer on the timeline panel by clicking the Shy button.It’s just hidden on the timeline panel, and it’s displayed as it is on the composition panel.Also, please be aware that it will displayed when you export the video!

The Shy button does not work just by turning it on on the timeline panel, so it is only enabled when [Hide Shy layers] at the top of the timeline panel is turned on.

②This button becomes a Collapse Transformation button in the case of a composition layer, and changes to a Continuously Rasterize button in the case of a vector layer.

Collapse Transformation is used when you want the layer to reflect the pre-composed settings when you have pre-composed multiple layers and put them together.

If the layer is a vector layer, you can edit continuous rasterization while checking with smooth lines without degrading the image even when enlarged.

③You can change the image quality of the layer displayed in the composition panel by clicking the Quality and Sampling button.Usually it’s Bilinear, but every time you click it, it changes to Bicubic or draft, and the image quality is degraded.

④By clicking the effect button, you can turn on and off the effect applied to the layer.When you put an effect on a layer, it is turned on, but when you click it off, you can turn off all the effects on that layer.

⑤The Frame Blend button is a function that interpolates when the playback speed of the layer is slowed down to play smoothly. This button switches between Frame Mix, Pixel Motion, and Off every time you click it.The frame mix mixes the front and rear frames and interpolates them. Pixel motion automatically generates and interpolates new frames from the previous and previous frames.

This button is only enabled when [Frame Blend] at the top of the timeline panel is turned on .

⑥Click the Motion Blur button to turn the motion blur on and off.

Similarly, this button is only enabled when Motion Blur at the top of the timeline panel is turned on.

⑦Check the Adjustment Layer button if you want the effect applied to the adjustment layer to affect the composition of the layer below it.

⑧The 3D layer button is a button to convert a 2D layer into a 3D layer, and then you can manipulate the layer in a 3D environment.

Mode Panel Description

The Mode Panel is used to configure settings for drawing modes or track mats.

This concludes the explanation of the timeline panel!
