How to split a clip in after effects

Is it possible to separate a single layer into two distinct layers in Adobe After Effects? Yes! 

It is useful when you want to have one layer end and another layer begins at the same point in the timeline.

If you want to split a clip in After Effect, follow these steps:

1. Import your clip into the software by going to the File menu > Import > File
   
2. Once the clip is imported, you can create a new composition by dragging it to the New Comp icon at the bottom of the Project window or by right-clicking on the clip and selecting “New Comp…”.
   
3. To split the layer, you must position the playhead at the desired point in the timeline. You can do this by using the Page Up and Page Down keys or by using the
4. CTRL + Left Arrow and CTRL + Right Arrow on Win or CMD + Left Arrow and CMD + Right Arrow on Mac shortcuts. Once the play head is in the correct position, you can split the layer by going to the Edit menu > Split Layer or using CTRL + Shift + D on Win or CMD + Shift + D on Mac
   In addition to splitting layers, you can also trim them.

   Trimming a layer involves cutting off the beginning or end of the clip to change its length.

There are two main ways to trim a layer in After Effects:

1. Simply grab the ends of the clip and drag them along the timeline to the desired point.
2. The second method involves Alt + [ on Win or Option + [ on Mac to trim the clip from the beginning, or Alt + ] on Win or Option + ] on Mac to trim the clip from the end. These shortcuts can be used with any type of layer: video, shape, solid, adjustment layer, etc.
   

It is also possible to trim and split multiple clips in the timeline at the same time.

1. Select the desired layers in the Layer panel. You can select multiple layers that are stacked together by holding down the Shift key and selecting the top and bottom of the stack, or you can select multiple clips that are not stacked by holding down the CTRL key on Win or CMD key on Mac and clicking on each layer you want to select.
   
2. Once the layers are selected, you can use any of the trimming or splitting methods mentioned above to edit all of the selected clips at once.
