Avid Media Composer Keyboard Shortcuts

Windows Ctrl is the modifier throughout, with Alt standing in for the button-click modifiers used in several editing functions.

Mac Cmd replaces Ctrl for most chords, but Option (not Cmd) is what pairs with the Alt-click editing functions, and a few timeline and bin shortcuts use the literal Control key instead of Cmd.

Playback and marking. J-K-L shuttle through footage at variable speed; I and O set Mark In and Mark Out points; 1/2/3/4 and the arrow keys step by frame.

Bins. Creating, duplicating, and printing bins, plus adjusting how clips display in Frame and Script view.

Editing. Splice, Overwrite, Lift, and Extract move material between the Source window and the sequence; Undo and Redo cover the last editing operation.

Timeline. Adding tracks, snapping to transitions, soloing tracks, and lassoing segments to enter Segment or Trim Mode.

Effects and rendering. Nesting effects, adjusting keyframes, and rendering without opening a dialog box.

A printable PDF of Avid Media Composer shortcuts is available for each platform. The J-K-L playback keys and the Mark In/Mark Out keys are worth learning first.

Adobe Premiere Pro, Adobe After Effects, DaVinci Resolve, Final Cut Pro, and Camtasia sit near Avid Media Composer because they cover the same professional video editing and finishing pipeline, not because they duplicate Media Composer's own workflow.

What do the J-K-L keys do in Media Composer?

They shuttle through footage at variable speed: L plays forward, J plays in reverse, and K pauses. Pressing L or J repeatedly increases the shuttle speed, and holding K while tapping J or L steps one frame at a time.

Are Media Composer's keyboard shortcuts the same on Windows and Mac?

Mostly. Ctrl on Windows becomes Cmd on Mac for most chords, but several shortcuts, including some timeline and bin commands, use the literal Control key on Mac instead of Cmd, and a few genuinely use different keys altogether.

Can I customize Media Composer's default keyboard shortcuts?

Yes. Most buttons and menu commands can be remapped to the keyboard through the Command Palette.
