Video · freemium

✓Audio is generated with the video in every mode, including image-to-video and extended scenes
✓Up to three reference images keep a character, prop or style consistent across separate shots
✓Scene extension and first/last-frame interpolation push output past the 8-second single-clip limit
✓Flow is a genuine editing and shot-management surface, not just a prompt field
✓Same model reachable as a consumer app, a Gemini API call and a Vertex AI enterprise endpoint

×Native audio is no longer a differentiator — Sora 2, Kling and Grok Imagine all ship it
×Per-second API pricing is expensive for volume work next to rivals' fast tiers
×Base clips are around 8 seconds; anything longer is stitched extensions, and drift accumulates
×No open weights and no non-Google distribution; consumer use is bounded by AI Pro/Ultra quotas that change without notice

✓Express-2 avatars produce script-matched gestures and intonation, not just lip movement over a fixed pose
✓Doc, URL, and slide-deck input generates a usable first-draft video instead of starting from an empty timeline
✓One-click translation re-voices a finished video across a large language set while keeping the same avatar
✓Real enterprise compliance stack — SOC 2 Type II, ISO/IEC 42001, SSO, SCORM export — that consumer-grade avatar tools do not offer
✓Free plan allows output-quality evaluation before any commitment

×Confined to presenter-led video — no cinematic footage, b-roll, or scenes without an avatar in frame
×Avatar realism is no longer a differentiator; HeyGen and Argil have effectively closed the gap
×Per-minute video allowances make high-volume production expensive compared with credit-based rivals
×The features enterprises actually need — custom brand avatars, SSO, SCORM — sit behind a sales quote with no published price
