AI video cost per second 2026
AI video cost per second in 2026 with audio included — how to compare Seedance, Veo, Kling, Flux, Wan, and H3 without lying to your budget.
AI video cost per second only works as a metric when audio, resolution, and regenerations sit in the same equation. A silent 720p preview and a 4K talking take are not one unit. Vendors know that. Budgets that ignore it blow up in week two.
The earlier landscape piece is AI video cost per second compared 2026. This page is the audio-inclusive planning method for late-2026 rows — including Seedance 2.5 and H3-class models — without inventing sticker prices that will stale by next week.
The only fair formula
Effective $/s = (credits or dollars for the kept take) ÷ (finished seconds you publish)
Then multiply by your real keep rate. If you keep 1 of 4 generates, your effective cost is 4× the sticker.
Include:
- Native audio on versus silent + separate TTS/lipsync
- Resolution tier (720p vs 1080p vs 4K)
- Motion-control or reference stack premiums
- Caption burn and upscale if they are separate meters
How families usually bias the math
| Bias | What happens to $/s |
|---|---|
| Always-on native audio (Veo-class) | Higher sticker, fewer surprise VO meters |
| Silent plate + lipsync later | Looks cheap until the mouth pass lands |
| 30s native pass | Lower stitch cost, higher blast radius per failed take |
| Motion control | You pay for transfer; you save on identity rerolls |
| Document-to-video | Saves scripting hours; still costs regenerations |

Versely-shaped budgeting
On Versely you plan in credits per row, visible before confirm. Practical habits:
- Price the kept Shorts open, not the experimental plate.
- Use free or cheap previews where the product offers them before full burns.
- Batch hooks with shared identity (motion control for UGC ads) so you are not paying full T2V identity search each time.
- Read the live card on models — blog posts should not outrank the meter.
FAQ
Should I compare vendor $/s to Versely credits 1:1? No. Convert through your credit price and the exact row. Cross-vendor $/s is directional.
Does longer native length always cost more? Usually yes per job; not always per finished usable second if it saves three stitches and three identity resets.
Where do captions land in the math? Burn-in is a separate render cost. Sidecar SRT is not a substitute for muted-feed ads.
