In non-linear editing, edits are specified and modified by specialized software. Each time the edited audio, video, or image is rendered, played back, or accessed, it is reconstructed from the original source and the specified editing steps. Although this process is more computationally intensive than directly modifying the original content, changing the edits themselves can be almost instantaneous, and it prevents further generation loss as the audio, video, or image is edited.
Timeline
The timeline is the area of a video editing application where you arrange your video clips and map out all the edits you’d like to apply. From start to finish, you’ll see all your video clips, audio clips, effects, and transitions laid out in chronological order as you work.
Bins
Where your assets are stored in a Video Project. It’s name originates from a trim bin from film editing.
Camera Slate
This tool is used to aid the editor in syncing visuals and audio when a scene is recorded on two separate devices (think film camera and audio recording device) The editor can sync the visual of the clapper closing to the audible click of the clapper. It also contains valuable information about the scene, take and camera set-up.
L Cut & J Cut
Cuts where the audio carries underneath the following/proceeding cut. It is referred to as an L/J cut based on its shape.

Track Select - [ a ]
lets you select all of the clips in a sequence, either forward or backwards
