Source clips, clip instances, and subclips

You can use clips as source clips, clip instances, subclips, or duplicate clips. You can edit all types of clips in sequences

in the same way. The clip types differ in the following ways:

Source (master) clip ThecliporiginallyimportedintotheProjectpanel.ItislistedintheProjectpanelonlyonceby

default. If you delete a source clip from the Project panel, all of its instances are also deleted.

Clip instance A dependent reference to a source clip, used in a sequence. Each time you add a clip to a sequence, you

create another instance of the clip. A clip instance uses the name and source file reference used by its source clip.

While clip instances are not listed in the Project panel, they are differentiated in the Source Monitor menu if you

open instances there. The Source Monitor menu lists instances by name, sequence name, and In point.

Duplicate clip An independent copy of a source clip, which you create manually using the Edit > Duplicate

command. Unlike a clip instance, a duplicate clip maintains its own reference to the original clip’s source file on disk

andexistsasanadditionalclipintheProjectpanel.Aduplicateclipisnotdeletedwhenyoudeleteitsoriginalfrom

the Project panel. Master and duplicate clips can be renamed independently.

Subclip A section of a master clip that references the master clip’s media file. Use subclips to organize and manage

your projects, especially when you need to use only sections of long master clips. (See “About subclips” on page 149.)

Working in the Timeline panel

About the Timeline panel

You assemble and rearrange sequences in the Timeline panel, which represents a sequence graphically, showing clips,

transitions, and effects. A sequence can consist of multiple video and audio tracks running parallel in the Timeline

panel.

Timeline panel

A. Sequence tabs B. Time ruler C. Video tracks D. Audio tracks

Each sequence in a project can appear as a tab in a single Timeline panel, or in a separate Timeline panel. A sequence

must contain at least one video track. Multiple video tracks are used to superimpose clips.
