The honest brief
Captions
Built on Mirage, its parent's in-house video foundation model — not a wrapper around third-party video generators.
- In-house Mirage video model
- Auto captions, B-roll, eye-contact fix
- AI personas render video from a script
- Multi-language dubbing
- Focused on talking-head/short-form only
- Best features behind paid tiers
- Avatar output can look synthetic
Hedra
Real-time Live Avatars stream lip-synced talking heads at sub-100ms latency, giving voice agents a face cheaply.
- Phoneme-accurate lip-sync from one image
- Streaming avatars at ~$0.05/min
- Expressive blinks/gaze from a photo
- Multi-model access in one platform
- Maxes out at 720p
- Fewer languages than HeyGen/Synthesia
- Limited public API
- Expiring-credit pricing friction
