First/last frame control
Constrains the opening and closing frame, suited to product showcases, pose transitions, and shorts that need a clear start and end state. Spelling out the motion in between makes results easier to control.

Kling O1 — Kuaishou's video model for fine-control multimodal shorts
What is Kling O1?
Kling O1 is the fine-control multimodal model in Kuaishou's Kling line; vendor materials emphasize first/last frame control, element reference, and aspect-ratio choices such as 16:9 / 9:16 / 1:1. Clips are commonly 5 or 10 seconds, suited to shorts that need finer subject constraints, product demos, and character-pose control. For new projects that need ~15s clips, native A/V, and a stronger element-production workflow, compare Kling 3.0 Omni. Select Kling O1 in the iMini video workspace to generate.

Element-reference guidance
Image and video elements can help guide subject and motion. For series characters or product clips, stack references first, then generate for a steadier result.
Flexible aspect ratios
Supports common aspect ratios including 16:9, 9:16, and 1:1. Vertical social shorts and square product demos can switch within the same model.
Upgrade path to 3.0 Omni
When you need a ~15s clip, native A/V, and a stronger video-element production workflow, compare Kling 3.0 Omni to upgrade and polish.
Choosing vs Kling 3.0 Omni and Kling 3.0
All belong to Kling's fine-control line. Differences come down to clip length, native A/V, and whether element reference has already moved into a production workflow.
