Which video model should I use?
Kling O3 Pro is the best quality per credit at 1080p. Seedance 1.5 Lite is the cheapest for drafts, and Seedance 2.5 is the only model that reaches 30 seconds.
Because video is billed per second, model choice matters far more here than it does for images. Pick by what the shot actually needs rather than by which name sounds most premium.
The quick answer
| If you want… | Use | Credits/sec |
|---|---|---|
| The best balance of quality and cost | Kling O3 Pro (1080p) | 18 |
| The cheapest usable draft | Seedance 1.5 Lite | 5 |
| Cheap video that already has audio | Seedance 1.5 Pro | 7 |
| A clip longer than 20 seconds | Seedance 2.5 (up to 30s) | 60 at 720p, 30 at 480p |
| 4K output | Kling O3 4K, or LTX 2 for the cheap route | 50, or 18 |
| Cinematic realism | Sora 2 Pro or VEO 3.1 | 35–85/sec, or per clip |
| Fast, affordable Google quality with sound | Gemini Omni Flash | 15 |
| Sharp 2K with strong character motion | Hailuo 03 | 35 |
| Motion-heavy or multi-shot scenes | WAN 2.6 | 12 at 720p, 18 at 1080p |
| The longest clip for the fewest credits | LTX 2 (up to 20s) | 6 at 1080p |
A sensible way to work
Draft on Seedance 1.5 Lite at 5 credits per second until the prompt and framing are right, then re-run the winner on Kling O3 Pro or better. A 5 second draft costs 25 credits; getting the same result by iterating directly on a premium model costs many times that.
Watch out for the per-clip models
VEO 3.1 and VEO 3.1 Fast are priced per clip, not per second — 225 to 338 and 120 to 190 credits respectively depending on audio. VEO 3.1 Lite is per second at 10 credits and is by far the cheapest way to get VEO output.
