📹 Modify Video

Standalone video tools accessible from the Video menu in the navigation bar. Each tool works independently - you don't need an existing project to use them.

Make AI-powered edits to any existing video. Upload a video and describe the changes you want.

Edit any existing video using a text prompt - change objects, backgrounds, colors, or style without reshooting.

All video tools share the same layout: upload panel on the left, History and How it Works tabs on the right. Select from Library is available on all tools to reuse existing assets.

Modify Video Steps

Follow these steps to get started:

• Go to Video → Modify Video
• Upload your video - drag & drop, paste URL, or select, from Library (max 200 MB, 10 seconds)
• Note the reference tag shown - e.g.,. @Video1
• Describe your change using the tag - e.g., 'Change cherry blossom with maple tree in @Video1.'
• Click Generate Video
• Preview and download from the right panel

Tips

Here are some tips to get the best results:

• Always include the @Video1 tag in your prompt - without it, the edit won't apply
• Be specific - 'Replace the red car with a blue truck' works better than 'change the car.'

Common Issues

If you run into problems, here are the most common issues and how to resolve them:

• Changes not applying - make sure @Video1 tag is in your prompt
• Upload fails - check file is under 200 MB and under 10 seconds
