Media Composer: Top and Tail Are Not on Your Keyboard Yet

The Real-World Scenario

You are cutting an interview. Every answer needs its front trimmed to remove the question and the pause. So for each one you enter trim mode, grab the head of the segment, drag it to roughly the right place, play it back, adjust, and exit trim mode. Three hundred times.

Two commands exist to do exactly this in one keystroke. Most editors never use them because Avid ships them unmapped, so they appear nowhere on the keyboard and nowhere in the default interface. A feature you have to install on yourself before using stays invisible.

The Solved Feature: Top and Tail

What the two commands do

Top removes the material to the left of the position indicator in the selected segment. Tail removes the material to the right. Park the indicator where the answer begins, press Top, and the front is gone in one action with no trim mode and no dragging.

The pair covers most interview and documentary assembly, where the work is finding the real start and end of a usable line and removing everything else.

Mapping them, which you have to do yourself

Open the Command Palette from the Tools menu. Choose the Edit tab, where the Top and Tail buttons live. Select Button to Reassign, then drag each button onto the keyboard position you want on the Keyboard settings window.

Editors commonly place them near their existing trim keys so the whole operation stays under one hand. The mapping saves into your user profile and travels with it between systems.

The workflow it enables

The gain compounds on long-form work. Play a take, stop where the usable material starts, press Top. Play forward to where it stops being usable, press Tail. Two keystrokes replace an entire trim-mode cycle, and the edit stays in the same rhythm as watching.

Working this way also keeps you in playback rather than in a mode. Judging where a line starts is easier while listening than while dragging a boundary and guessing.

Pro Tips and Gotchas

• Both commands act on the selected segment and the enabled tracks. Check your track selectors before pressing, or you trim picture and leave audio behind.
• These commands remove material rather than moving edit points, so surrounding segments do not shift. Use them for assembly and normal trim for adjusting cuts in a locked sequence.
• The Command Palette holds a large number of other unmapped commands. Reading the Edit and Play tabs once is worth the ten minutes.
