## Overview

By default, Reap aligns captions automatically. When you need more control, the **Timing Sidebar** lets you manually adjust when captions appear and disappear.

This page includes a product walkthrough video, followed by the same workflow as written steps below.

## Step-By-Step Workflow

<Steps>
  <Step title="Open the Timing Sidebar">
    Select a clip with captions and click the edit button below the clip. In the right panel with the transcription box, click **Timing Sidebar**.
  </Step>

  <Step title="Review caption segments">
    Each caption line includes a start handle and an end handle. The highlighted bars show exactly when a caption is visible.
  </Step>

  <Step title="Adjust caption timing">
    Drag the handles left or right to change start and end times. Use frame-level precision when you need more exact timing.
  </Step>

  <Step title="Preview and test">
    Press **Play** in the preview window and watch for captions that appear too early, too late, or cut off mid-sentence.
  </Step>

  <Step title="Reset or undo when needed">
    Use `Ctrl+Z` / `Cmd+Z` or the editor undo/redo buttons to reverse a timing change. Refresh the editor if you want to reset a caption back to Reap's default timing.
  </Step>
</Steps>

## Troubleshooting

* If changes do not save, make sure you click **Apply** before leaving the editor.
* If captions look out of sync after export, reopen the project and test the timing again.
* If the sidebar is not visible, refresh the editor and confirm captions are already generated.
