AutoB-Rolls helps you automatically enhance your edits by adding relevant visuals to your video. You can use existing stock footage or generate AI-based images to bring your content to life without manually searching for visuals. Watch our quick YouTube tutorial to get started :

Step 1: Choose Language & Set AI Prompt Style

Start by selecting the language of your video’s audio.

Then, define your AI prompt style: this setting influences the type of images that will be generated later. You can adapt the prompt to match the tone, theme, or aesthetic of your video content.

Step 2: Detect B-Roll Sections

AutoCut gives you 2 options for identifying where to insert B-rolls :

• Automatic detection using AI to find the most relevant parts of your transcript
• Manual selection: highlight specific transcript sections and click “Confirm selected transcript” to mark them for B-roll insertion

Choose the method that best suits your editing process.

Step 3: Add B-Rolls (Stock or AI-Generated)

Once your B-roll sections are selected, choose the type of content you want to insert :

• Existing stock footage: Video clips from Pexels or Storyblocks.
• AI-generated images: Still images based on your earlier prompt

AutoB-Rolls will insert the selected media at the chosen positions in your timeline. You can also enable "Auto-Fill" so AutoCut automatically finds relevant B-rolls or images for each section.

You will then be able to review the inserted media and replace it if it doesn’t match your needs.
