How can I change the duration of my video?

You can change the duration of your video from the Edit Script section.

For this, click on the Edit option and navigate to the Edit Script section.

Now, you can add chapters to increase the length of the video or delete chapters to reduce the overall length of the video.

Note: If you add new chapters, you will also need to add media keywords for the AI to show you a relevant image/video which you can then later on replace with your own.

Once done, click on the Apply Changes option to save your changes.
