Seedance vs Kling: clip lengths compared
Which clip lengths Seedance 2.5, Seedance 2.0 and Kling 3.0 offer, and how to plan your cuts around them.
The lengths you can choose
Every AI video model lets you pick from a fixed set of clip lengths. These are the presets built into Cut Maker as of October 2026:
| Model | Clip lengths |
|---|---|
| Seedance 2.5 | 4 to 30 seconds, any whole second |
| Seedance 2.0 | 4, 5, 6, 8, 10, 12 or 15 seconds |
| Kling 3.0 | 3 to 15 seconds, any whole second |
| Older models | 5 or 10 seconds only |
Platforms update their models often, so check the length menu in the tool you use. If your model isn't listed, Cut Maker lets you set a custom range.
What the difference means for your script
Seedance 2.5 gives you the most room. A long, emotional line can live in one 20-second clip instead of being split. That's useful for monologues and slow dramatic beats.
Kling 3.0 tops out at 15 seconds but lets you pick any second in between. That makes it easy to match each cut to its dialogue exactly — a 7-second cut for a 7-second exchange, with no wasted seconds.
Seedance 2.0 has gaps: there is no 7, 9, 11, 13 or 14-second option. A cut that needs 11 seconds has to be rounded up to 12, which costs an extra second of credits.
Older 5/10-second models force you to write in small blocks. Anything over 10 seconds must be split.
Which one should you pick?
- Short, punchy dialogue: any model works. Pick the cheapest that looks right.
- Long lines you don't want to split: Seedance 2.5.
- Exact timing to save credits: Kling 3.0 or Seedance 2.5, because you pay only for the seconds you need.
