Looping

Any motion. Perfect loop. No seam.

Select any motion — generated from text, extracted from video, or pulled from the library — and Uthana's AI generates a natural transition from the end back to the start. The result is a clean, seamless loop ready for idle states, walk cycles, ambient animation, or anything that needs to repeat.

Select. Adjust. Loop.

1. Pick a motion

Pick any motion saved to your Uthana account — generated from text, video, recorded in real-time or grabbed from the library.

2. Adjust timing

Adjust the frame that will represent the start/end frame and the speed and position of the in-betweening frames that will be generated.

‍

3. Loop it

Uthana's AI models generate a physically natural in-between that ends with the starting frame, creating a perfect loop cycle.

Download for full control

Once you're happy with the looped result, download it as a single FBX or GLB file with complete, clean keyframes from start to finish, including the transition. Open it in Blender, Maya, or any DCC and adjust whatever you need. The output is standard motion data, not locked or baked into a proprietary format.

  • One continuous motion file
  • Export for Blender, Maya, Unity, Unreal, and Roblox Studio
  • Download with full keyframe data for final polish

Handles any starting and ending pose

Traditional looping requires your clip's first and last frames to already be close to matching — which means trimming, adjusting, and often compromising the motion. Uthana's approach works in reverse: give it any motion, and the AI figures out how to get from the end back to the start naturally. A motion that ends in a wide stance and starts with arms raised? The model generates the transition between them.

‍

  • No need to pre-trim or match start and end poses
  • Resolves differences in position and orientation
  • Handles everything from subtle idles to dynamic actions

Physics-aware in-between frames

The beginning and end of your motion don't need to match. The looping model generates a realistic motion between them that isn't just interpolation but new animation generation. Changes in trajectory, body orientation, and movement intensity are all resolved in the transition, and the motion accounts for how a real body would move between those two states.

‍

  • Bridges differences in speed and momentum naturally
  • Resolves changes in direction and body orientation
  • Handles transitions between different action types
FAQ
Frequently asked questions about Uthana looping
â–¶

How fast is looping?

Transitions are typically generated in under 10 seconds. You can go from selecting a motion to previewing the stitched result in well under a minute.

â–¶

Does the motion need to start and end in a similar pose?

No — that's the key difference from traditional looping. Uthana generates new motion to bridge the gap between the end and the start, so it works regardless of how different the two poses are. That said, motions that are already somewhat cyclical (walks, jogs, breathing) will produce the most natural-looking loops.

â–¶

What's the difference between looping and stitching?

Both use the same underlying AI to generate natural transitions. Stitching connects two different motions into a sequence. Looping connects the end of a single motion back to its own start, creating a seamless repeating cycle.

â–¶

Is looping available through the API?

Full support for looping is available in the webapp. API access is currently in preview - it's in an unstable state with changes expected soon. For the most technically inclined users, try stitching programatically with the API.

â–¶

Does looping change my original motion?

No. Your original clip is preserved as-is. Looping creates a new motion file that includes the original plus the AI-generated transition back to the start.

â–¶

Will the loop play seamlessly in Maya/Blender/Unreal/Unity/Roblox Studio?

Yes. The downloaded file is a single continuous motion with clean keyframes. When you set it to loop in your engine's animation system, it plays back seamlessly — no additional blending or wrap settings required.

â–¶

What kinds of motions loop best?

Any motion can be looped! Naturally cyclical actions produce great results, but so do complex actions with good tuning.

â–¶

Can I preview the loop before downloading?

Yes. Every loop can be previewed playing continuously in the browser before you commit to a download. Previews don't count against your download seconds.
