Sora vs Kling vs Runway — generated video compared
Generated video improved faster than any other category this year, and the differences between these three are now about workflow and availability rather than raw quality.

Choosing by job
- Producing a finished clip, including edits → Runway, because the editing tools are in the same place
- Longer or higher-resolution output → Kling, which leads on both
- Complex prompts where the scene must stay coherent → Sora
- Corporate production in Japan → confirm vendor jurisdiction before committing to Kling
What none of them do well yet
- Consistent characters across multiple clips
- Readable text inside the frame
- Precise control over timing to the frame
- Anything requiring exact continuity between shots
Which means generated video currently fits B-roll, abstract sequences and short social content. A narrative piece requiring continuity is still a conventional production with generated elements in it.
Can I use generated video commercially?
On paid plans, generally yes, subject to each platform's current terms. Check whether your use involves recognisable people or brands, which is a separate question from the licence.
How long can clips be?
It moves constantly and Kling has generally led on length. Verify against current documentation rather than any article, including this one.
