You can split any Video layer into one or multiple video layers. This way you can automate away your manual work when creating shorter clips from a  longer video. 

To cut away content from both the start and the end, first create a separate clip by snipping off the beginning, then another clip by snipping off the end.

Split a video layer

1. Select one or more video layer(s).
2. Move the timeline playhead to the new starting point.
3. Click the scissor icon.
   The layer splits in two at the position you selected, generating a new clip.

Split a video layer with keyframes

When you split a video layer that contains keyframes, what happens is:

• If you split a layer before or after a keyframe, the keyframe is included in only one clip.
• If you split during a keyframe, both clips get the same keyframes, but in the ratio to their own length. If the original video layer had a keyframe 1/3 of its length, both of the new video layer clips get a keyframe that is 1/3 of their own length.

Enabling the video splitting button

If your video splitting button is disabled, it means that the selection is empty or contains content that can't be split. Select a layer, or if you have already done so, make sure that all the layers are valid for splitting.
