Generate b-roll for the parts you talk over
Ask the Tella Agent to generate video clips or images for the moments that need b-roll and place them over your recording.
Try it in Tella
Paste a prompt into the Tella Agent in the editor, or into Claude or ChatGPT connected to Tella, then ask for changes.
Find three moments in my intro where b-roll would help. Generate a short video clip for each that matches what I'm saying and place it over that moment. Keep each under five seconds, in a warm, natural style.
Wherever I describe a place, object or historical moment, generate a photographic image and show it as b-roll with a slow push-in. Keep the style consistent throughout.
Over the part about remote teams, add a b-roll clip of a person on a laptop in a bright modern office, close-up, shallow depth of field. Use the cheapest video model for a first draft.
How do I generate b-roll for a video with AI?
Ask the Tella Agent in Tella's editor for b-roll and say where it goes, or let it pick moments from your transcript. It generates short video clips or images and places them over your recording. The picture changes while your voice keeps playing. You can also generate clips yourself from Generate at the top of the Media Library.
How to do it
- Open your video in the Tella editor and open the Tella Agent.
- Say what the b-roll should show, where it goes, and clip or image.
- Attach an image if you want results to match its look.
- Review placement and ask the agent to move, trim or regenerate any.
