Today, we’re introducing AI Video Presets in Assistant — a faster way to get b-roll that looks made for you. Available on all plans.
How it works and why it matters
When you create a video with the Assistant, Synthesia can now automatically fill eligible b-roll slots with a curated AI video clip:
- Matched to your scene (so the visuals fit the setting)
- Featuring your Avatar (from your brand kit, in a matching outfit)
- Delivered in seconds, using a catalog of pre-rendered clips
- Free to use, with no extra prompting, selecting, or opting in
The result: your videos look more consistent and more “you,” without extra work in the Editor.
