# Edit a video, add audio and export

Arrange scenes and timeline clips, add media, music, voiceover and captions, use available AI tools and export a finished video.

## Before you start

Open a project from **Your videos**. Editing requires workspace editor access; viewers get preview only. If **Video Studio** is missing from the menu, it isn't enabled for the workspace yet. Wait until uploaded media is ready.

A computer opens the hosted editor with a timeline. A phone opens the scene-based storyboard. Instructions below identify the relevant surface instead of assuming the controls are identical.

## Arrange visuals

1. On a phone, choose **+ Media** to select photos and clips. On a computer, use the editor's add-media action and complete the [Add-media window](https://docs.lead-knight.com/en/video-studio/add-media/).
2. In **Scenes** on a phone, select a scene to open **Edit scene**. Adjust a photo's duration or use **Trim** with **Source start** and **Source end** for a video. Duration controls respect the limits shown for that scene.
3. Change **Scene text** and **Text style** as needed. Choose **Transition to the next scene** and **Transition duration**; choices include **None**, **Fade**, **Slide**, **Wipe** and **Zoom**.
4. Reorder scenes by dragging. Keyboard users can press Space to pick up, arrow keys to move and Space to drop; Escape cancels. Use **Delete scene** only after checking the confirmation.
5. On a computer, select the timeline clip and put the playhead at the intended cut. **Split here**, **Trim start** and **Trim end** act on the editable clip/playhead selection. Disabled controls mean that selection cannot perform the action; move the playhead or select a suitable clip first.
6. Play the video to check timing. Phone thumbnails are an alternative when live preview is unsupported; **Create a 540p preview** is offered as another preview path. Extra layers may require editing on a computer.

## Music and voiceover

1. Open **Music**. Choose from **Music library** / **Free music**, **Project audio**, **Upload audio** or **Create music** where offered.
2. Preview a track before using it. Follow any **Credit required when publishing** notice and use **Copy credit**. For uploaded or recorded audio, confirm that you own the rights or have a commercial-use licence.
3. For generated music, enter the request or choose an offered mood, review duration and cost, then **Generate** when available.
4. Open **Voiceover**. For **Text to speech**, enter **Voiceover script**, choose language and voice, review the displayed cost and generate.
5. On a phone, **Record voice** offers **Start recording**, **Stop recording**, **Use recording** and **Discard recording**. Allow microphone access. A recording can be up to 180 seconds; closing the sheet before adding it discards it. Voiceover starts at the beginning of the video.
6. Preview the whole video with audio, not just the individual track. Save the changes using the action offered by that editor.

## Captions

1. Open **Captions** and choose **Generate captions**. They follow speech in audible timeline clips; caption generation does not use AI credits.
2. Review **Edit caption text**, then choose **Caption style**, **Position** and **Text size** as offered. Correct names, numbers and any transcription errors.
3. Use **Apply changes** / **Save changes** as offered. Regenerating captions replaces your existing caption text edits and styling after confirmation. **Turn captions off** also asks before removing them.

## Available AI visuals

Use only AI options enabled for the project. **Animate with AI** needs a ready photo scene; **AI clip** creates a new clip from a request. Available choices can include **Duration (seconds)**, **Quality** and sound. Where multiple tiers are offered, **Lite**, **Standard** and **Premium** are capability-dependent choices, not a promise that every tier is enabled.

Review the cost quote and remaining credits before **Generate**. Unsupported aspect ratios, missing source media, read-only access or insufficient credits can disable generation. The result is added when ready; check the actual insertion or replacement message on the surface you are using.

**Restyle with AI** / clip editing marked **Soon** is not an available action and is not part of this workflow.

## Save, export and use the result

1. Wait for **Saved** or complete **Save changes**. Do not leave while the editor reports unsaved changes.
2. Wait for pending AI clips to finish; they block export.
3. Choose **Export** and the offered **Resolution**. The desktop export dialog offers 720p and 1080p.
4. Start export and keep the tab open. For device export, keep it in front on a computer or the page open and screen on on a phone. If device export is unsupported or fails, the interface can report a server export instead.
5. Wait for the finished preview, play it and inspect audio, captions and visuals. An export progress message is not yet a finished file.
6. Choose **Download** for the video file. **Use in campaign** can first save a locally created result to the account; follow any saving/uploading status before continuing. Once stored, the desktop action can read **Open new campaign**.
7. Review the campaign draft and publication settings. A valid linked-campaign handoff can return to that campaign; otherwise a new campaign is started. Exporting or handing off does not itself publish.

## If something goes wrong

| Symptom | Recovery |
|---|---|
| Save failed | Changes remain on screen. Use **Retry saving** before leaving. |
| Conflicting changes | **Download my changes** before **Load latest**; the editor cannot safely merge concurrent work. |
| AI cost unavailable | Retry the cost check; do not assume generation is free. |
| Generation failed | Retry or remove the pending item. If retry details are missing, remove it and start a new generation. |
| Microphone unavailable | Allow access or use text-to-speech; unsupported browsers cannot record. |
| Export failed | Ensure media is ready and edits saved, then retry. |
| Text behind subject blocks export | Keep that effect within 20 seconds per video and use Chrome/Edge on desktop or Android, or disable the effect. |
| Download link unavailable | Use **Refresh download link** where offered. A ready render can exist even when its link cannot be loaded. |
