# Retiming and Trimming

> Adjust clip speed and boundaries so screen walkthroughs stay clear and efficient.

## Overview

Use retiming and trimming to remove dead time while keeping each action understandable.

## Before you start

* Confirm the recording is fully processed.
* Align rough scene order before fine timing.
* If narration exists, keep it visible while retiming.

## Core tools

* **Trim handles**: remove extra lead-in/out around useful actions.
* **Speed controls**: compress repetitive actions or slow down dense moments.
* **Split points**: apply different timing to different sections.
* **Preview loop**: repeatedly test the exact segment you changed.

## Steps

1. Trim obvious dead space at clip boundaries.
2. Add split points around high-information moments.
3. Apply speed changes per segment, not globally.
4. Recheck narration/caption sync after each speed edit.
5. Run a full scene preview to verify rhythm.

## Check your result

* No unnecessary waiting remains.
* Critical UI actions still read clearly.
* Adjacent narration and captions stay aligned.

## Troubleshooting

### Narration no longer matches actions

Speed edits can break sync. Re-align clip offsets and revisit nearby split points.

### Transitions feel abrupt

Move split points to natural pauses and avoid aggressive speed jumps at scene boundaries.

### Clip became too short

Undo the last trim/speed operation and reapply in smaller increments.
