# No lipsync

> Keep parts of a Studio Pro video unchanged while timeline audio plays over them.

Use **No lipsync** for reaction shots, cutaways, or other footage whose mouth movements should stay unchanged. The marked footage remains in the output, with the timeline audio playing over it.

## Mark footage

1. Select a clip, or mark a range with **Mark in** and **Mark out**. The keyboard shortcuts are **I** and **O**.
2. Select **Disable lipsync** in the toolbar, or press **Shift+E**. A **No lipsync** band appears over the footage.
3. Generate the video. Studio lip-syncs the unmarked footage.

A marked range takes priority over selected clips. For an audio clip, the action marks the video beneath it. You can also right-click a clip and select **Don't lipsync this clip**.

## Restore lipsync

Select the marked footage and choose **Restore lipsync**, or press **Shift+E** again. You can also select the **No lipsync** band label or use **Lipsync this clip** in the clip menu.

Ranges move with their video clips and are saved with the project. Completed generations show the ranges without allowing edits. The estimate excludes footage marked No lipsync.

## Resolve generation errors

If Studio says **Nothing to lipsync**, restore lipsync for at least one part of the video that has audio.

A timeline can contain up to 100 lipsync segments. Audio clips split by No lipsync ranges can create several segments. If Studio reports too many segments, reduce the number of clips or ranges.

If Studio cannot load the timeline audio for the marked footage, check your connection and try again.
