# Review and revise your video
> Leave comments on a frame or time range, send them to Voyager, and compare the next version.
Point to the exact moment or detail you want changed, then send your notes to the agent in the same chat.
You need a video you can open in Voyager, such as the result from [your first video](/first-video/make-your-first-video). You can also revise it with an ordinary message: “Make the final title larger and keep everything else.”
## Leave a review
Hover over the video in the agent's reply and click **Review**. You can also right-click it and choose **Review video**.
Play or pause with Space. Use the left and right arrow keys to move a frame at a time.
Use the pin tool to point to a detail, the pen to draw, or the box tool to surround an area. Their shortcuts are P, D and B. Write a concrete note, such as “Make this title about a third larger, keeping it centered,” then click **Save**.
For a change that covers several seconds, use **Select time range** at the timeline. Set **In** and **Out**, then add your note. You can use I and O to set the range while reviewing.
For example: “Slow this entrance down, but keep the title fully visible for the final two seconds.” A range is more useful than a single frame for pacing, transitions or audio.
A revision that generates new images, clips, music or voice can cost money. Review the new estimate and your [question-answer mode and spend limit](/guides/approvals-and-spending) before approving paid work.
Click **Attach** followed by the comment count, such as **Attach 3**. This puts a review attachment in the message box. Add your instruction and send it:
```text theme={"system"}
Apply these notes. Keep the parts I haven't commented on.
Save a new version and keep the original.
```
**Attach** stages the notes; it does not send a message. **Send now** on a comment sends that note immediately. Use **Save** while collecting several notes, then **Attach** to send them together.
## Compare the result
Open **Assets** in the right panel and select the output. When it has suitable versions to compare, click **Compare** and choose the two versions.
| View | Use it to check |
| - | - |
| **Side by side** | Both versions at once. |
| **Wipe** | Differences across the same picture using a divider. |
| **Flip** | One version at a time, switching between them. |
Play the revised section and the complete video. A title change may look right in one frame but arrive too early in motion. Keep giving feedback in the same chat so the agent has the earlier decisions.
## Common problems
Look for the review attachment in the message box. Add an instruction and click **Send**. Attaching a review does not start a revision by itself.
Open the intended version and attach a review from that file. Name the version in your message and say what should stay unchanged.
Check that you selected an output with more than one comparable version in **Assets**. If the revision is a separate output, ask the agent to present it as the next version of the original.
Open the finished version in your file manager or save a copy.
