The longest single clips in 2026 come from Wan 3.0 (2 to 30 seconds) and Seedance 2.5 (4 to 30 seconds). Kling v3, Hailuo H3, Happy Horse and Grok Imagine stop at 15 seconds, Gemini Omni Flash at 10, and Veo 3.1 at 8. Anything longer is made by joining clips, which is also usually the better way to make it. These are the ranges each model offers on 8frame, taken from the models' current settings on the canvas.
TL;DR
- Up to 30 s: Wan 3.0 and Wan 3.0 Prime (2 to 30), Seedance 2.5 (4 to 30).
- Up to 15 s: Kling v3 and Kling O3 (3 to 15), Hailuo H3 (5 to 15), Happy Horse (3 to 15), Seedance 2.0 (4 to 15), Grok Imagine (1 to 15).
- Up to 10 s: Gemini Omni Flash (3 to 10), Runway Gen-4 Turbo (2 to 10), and the older Kling versions (5 or 10 only).
- Up to 8 s: Veo 3.1, in 4, 6 or 8 seconds.
- Longer than 30 s means several clips joined. On 8frame, Merge Videos joins them for 10 credits.
Every model, one table
| Model | Clip length on 8frame |
|---|---|
| Wan 3.0, Wan 3.0 Prime | 2 to 30 s, any whole second |
| Seedance 2.5 | 4 to 30 s |
| Seedance 2.0 | 4 to 15 s |
| Kling v3 Standard and Pro, Kling O3 | 3 to 15 s |
| Kling 2.6 Pro, 2.5, 2.1, O1 | 5 or 10 s |
| Hailuo H3 | 5 to 15 s |
| Happy Horse | 3 to 15 s |
| Grok Imagine | 1 to 15 s |
| Gemini Omni Flash | 3 to 10 s |
| Runway Gen-4 Turbo | 2 to 10 s |
| Veo 3.1, Fast, Lite | 4, 6 or 8 s |
Seedance also has an automatic length option that lets the model choose. Nothing below 4 seconds is offered on Seedance because the model does not support it.
What the long end costs
Length is a priced dimension almost everywhere, and it scales close to linearly. Credits on 8frame, a credit being about $0.01 at pack rate:
| Model | Short | Long |
|---|---|---|
| Wan 3.0, 480p | 5 s: 24 | 30 s: 142 |
| Wan 3.0, 1080p | 5 s: 95 | 30 s: 567 |
| Wan 3.0 Prime, 480p | 5 s: 46 | 30 s: 276 |
| Kling v3 Standard, with audio | 5 s: 86 | 10 s: 171 |
| Hailuo H3 | 5 s: 88 | 15 s: 264 |
| Gemini Omni Flash | 3 s: 51 | 10 s: 169 |
| Runway Gen-4 Turbo | 2 s: 16 | 10 s: 80 |
| Veo 3.1 Lite, with audio | 4 s: 27 | 8 s: 54 |
The cheapest 30 seconds in one take is Wan 3.0 at 480p, 142 credits. Watch the Wan default: it is 1080p, which makes the same 30 seconds 567.
Should you make one long clip or several short ones?
One long generation is one roll of the dice. If second 22 has a physics glitch, you regenerate all 30 seconds. Six 5-second clips can each be redone on their own, and a cut between them hides the seams that a single take cannot.
Long single takes earn their price in a few cases: a continuous camera move, a slow reveal, an ambient loop where a cut would be visible. For everything else, draft short, then join. The trade-offs are argued in best AI video generator for long clips, and joining is covered in how to use Merge Videos.
Extending instead of regenerating
Two models on 8frame can continue an existing clip rather than start a new one. Grok Imagine has an extend mode that adds 2 to 10 seconds. Gemini Omni Flash can extend uploaded video up to 10 seconds long, except in the EEA, Switzerland and the UK, where Google does not offer editing or extending uploaded video.
FAQ
What is the longest AI video you can generate in one go? 30 seconds, on Wan 3.0 (2 to 30 s) or Seedance 2.5 (4 to 30 s). Most other models stop at 10 or 15.
How long can a Seedance video be? Seedance 2.5 goes from 4 to 30 seconds; Seedance 2.0 from 4 to 15.

How long can a Veo 3.1 video be? 4, 6 or 8 seconds per generation.
How do I make a one-minute AI video? Generate several clips and join them. A one-minute cost breakdown is in how much a one-minute AI video costs.
Draft in 5-second pieces, keep the 30-second take for the shot that needs it. The 8frame canvas is free and unlimited, and generation is paid from $19/month.
