- **Kling 4.0.** Clips from 3 to 30 seconds with audio, at 720p or 1080p. Give it a start frame, an end frame, or go ultra-wide at 21:9.
- **Grok Imagine Video 1.5.** Native 1080p with lip-synced audio, plus 480p and 720p options. A cheaper Lite version came right after.
- **How to use them.** Ask Viktor for either by name. Seedance 2.5 is still the default, so nothing changes unless you pick one.
