AI Performance CapturePerform the Scene. Direct the Character.

Record or upload a short acting take to guide your character's dialogue timing, expressions, visible gestures, body language, and voice in a finished video. No mocap suit, rigging, or keyframes.
Camera or upload3–30 second takes720p or 1080p

Act out the full scene in one clear shot. Keep one performer visible and record clean audio so the model has a stronger performance signal.

Use a clear JPG or PNG with one visible, human-like character. Similar framing and an opening pose close to the performer usually improve consistency.

Upload the character image and motion reference together before generating.

Choose whether the result follows the performer's angle or stays closer to the character image.

Available with Kling 3.0. Choose which input guides the generated background; neither option is a pixel-perfect background lock.

Your video drives the acting. Use the prompt only to guide the scene around the character.

Your driving video guides the timing, expression, visible gestures, lip sync, and audio. The result is AI-generated, so facial, hand, background, and motion details can vary.

A Finished Character Video, Not a 3D Mocap File

This workflow creates a rendered 720p or 1080p character video from one character image and one recorded performance. It does not export a 3D skeleton, blendshapes, FBX, BVH, or GLB files, and it does not create a live rig for Blender, Maya, Unreal Engine, or Unity.

Choose AI motion capture or markerless mocap when you need editable 3D animation data. Choose AI Performance Capture when you want to perform the scene yourself and download a character-led video.

Direct Character Videos with Your Own Performance

A prompt can describe an action. Your acting take directs the pauses, emphasis, reactions, gestures, and emotional timing that make the scene feel intentional.

Record Yourself in the Browser

Use your camera and microphone to perform directly, or upload a take recorded on your phone. The built-in recorder keeps browser recordings within the supported duration.

Direct Timing and Emotion

Use your own pauses, emphasis, reactions, and changes in energy to guide the generated character instead of asking a text prompt to guess the delivery.

Direct Timing and Emotion

Guide Visible Gestures and Body Language

Head movement, posture, upper-body acting, and clearly visible hand gestures give the model more specific direction. Small, hidden, or very fast movements may be simplified.

Guide Visible Gestures and Body Language

Choose the Strongest 3–30 Second Take

Trim a desktop upload before generating. On mobile, record or select a continuous 3–30 second clip with the device camera when browser-side trimming is unavailable.

Voice-Led Delivery and Lip Sync

The driving video's audio guides the spoken delivery and generated mouth movement. Use a clear voice recording and review the preview because lip-sync accuracy can vary by take and model.

Voice-Led Delivery and Lip Sync

Preview First, Finish in 1080p

Use 720p to check framing, identity, gestures, and timing at a lower cost. Move to 1080p after the performance looks right, then choose the supported orientation and background source.

How AI Performance Capture Works

Go from your acting take and a character image to a finished character-led video in three steps.

1

Record or upload your performance

Act the scene in one continuous take. Speak naturally, keep one performer visible, and keep important gestures inside the frame.

2

Choose a clear character image

Upload one readable, human-like character. Portraits, illustrated mascots, anime art, and stylized renders work best when their framing resembles the performer.

3

Preview, refine, and generate

Generate a 720p preview, check the identity and performance, then adjust the inputs or create a higher-detail 1080p version.

What Is AI Performance Capture?

AI performance capture is an actor-led character video workflow. Instead of describing motion with text, you record the scene yourself so the model can use your timing, facial acting, body language, visible gestures, and voice as creative direction.

Traditional performance capture often produces editable 3D motion or facial data for a VFX pipeline. This page uses the Motion Control AI generation platform for a different result: a rendered character video designed for creators, presenters, storytellers, and brand teams.

What Transfers, What Can Vary, and What Is Not Included

Performance capture is generative, not a frame-by-frame copy. Clear expectations help you choose the right input and the right tool.

Designed to Carry the Performance

Dialogue timing, head movement, clear facial reactions, posture, upper-body motion, visible gestures, and source audio provide the main direction for the generated take.

Results Depend on the Input

Small fingers, fast movement, side profiles, occlusion, extreme expressions, large full-body travel, character identity, and background details may drift or be simplified.

Not a 3D or Real-Time Rig

The workflow does not provide FBX, BVH, GLB, a 3D skeleton, blendshapes, real-time puppeteering, exact motion tracking, or independent control of multiple performers.

AI Performance Capture for Dialogue, Reactions, and Presenters

Use your own delivery for character-led content where timing, voice, and emotion matter more than a generic motion preset.

Host and Presenter Videos

Perform a product explanation, tutorial, or announcement and use the take to direct a virtual host or mascot.

Emotional Dialogue

Direct pauses, emphasis, facial reactions, and body language for short monologues and character scenes.

Reaction and Social Clips

Turn surprise, excitement, disbelief, or subtle reactions into expressive short-form character content.

Podcast and Interview Moments

Recreate a short speaking segment with a character while keeping the rhythm and intent of the original delivery.

Music and Performance Clips

Use vocal timing, head movement, hand emphasis, and stage presence to guide a stylized character take. Preview carefully when movement is fast.

Brand Mascot Explainers

Give a mascot the delivery of a real spokesperson for explainers, onboarding, campaign concepts, and social posts.

Record Better Inputs for AI Performance Capture

A clean, continuous take gives the model clearer direction and makes the preview easier to evaluate.

Framing

Keep one performer visible

Frame one person clearly from the waist or chest up, with the face and important hand gestures visible.

Continuity

Use one continuous shot

Avoid cuts, sudden camera movement, heavy occlusion, and abrupt changes that interrupt the performance signal.

Audio

Record a clean voice track

Reduce background noise and keep the microphone level consistent so the model receives a clearer audio reference.

Consistency

Match framing and the opening pose

Use a character image with a similar camera angle, body crop, and starting pose when you want a steadier transition into the take.

Quick input check

One continuous 3–30 second take

Follow the active duration shown in the generator and avoid edits inside the clip.

Check 720p before 1080p

Confirm identity, framing, hands, and timing before spending more on the final version.

Get a Stronger First Take

Use the checklist before generating, then match common visual problems with a practical adjustment.

Before you generate

  • Use one performer and one continuous 3–30 second clip.
  • Keep the face and important hand gestures visible from the start.
  • Match the character image to the performer's half-body or full-body framing.
  • Use moderate movement without sudden turns, fast travel, or heavy occlusion.
  • Keep the camera steady and avoid cuts or large zoom changes.
  • Record clear, consistent voice audio when spoken delivery matters.
  • Leave enough room in the frame for the largest gesture.
  • Start with 720p, evaluate the result, and use 1080p after the take works.

Common problems and practical fixes

Problem
What to change
The opening pose jumps
Use a character image with a camera angle, crop, and starting pose closer to the first frame of the performance.
Hands look unstable
Move closer, keep both hands visible from the start, reduce speed, and avoid crossing them over the face or body.
Lip sync feels weak
Use clearer audio, keep the face larger and more frontal, and avoid speech during large head turns.
The character identity drifts
Use a clearer single-character image and reduce extreme angle changes, occlusion, and very fast facial motion.
The background changes
Choose the supported background source deliberately and allow for generative variation; this is not pixel-perfect person replacement.
The usable output becomes shorter
Remove cuts, simplify rapid motion, and use a shorter continuous section with a clear performer throughout.

AI Performance Capture FAQ

What does AI Performance Capture transfer?
It uses the driving video to guide timing, visible facial reactions, posture, head movement, upper-body action, hand gestures, lip sync, and audio. It is generative rather than an exact tracking system, so the fidelity of each detail depends on the model and input.
Does this export FBX, BVH, GLB, or 3D motion data?
No. The current workflow downloads a finished character video. It does not export a 3D skeleton, blendshapes, a rig, or FBX, BVH, and GLB animation files.
Is AI Performance Capture the same as AI motion capture?
They overlap, but the expected output is different. AI motion capture usually means extracting editable 3D movement data for Blender, Maya, Unreal Engine, or Unity. This page uses your performance to generate a rendered character video.
Can I record my performance directly on this page?
Yes. Supported browsers can record with the camera and microphone inside the form. Mobile devices can also open the native camera when browser recording or desktop video processing is unavailable.
Does the result keep my original audio and lip sync?
The selected motion-control workflow is designed to carry the driving video's audio into the generated take and use it to guide mouth movement. Because audio handling and lip sync are model-generated, use clear source audio and review the 720p preview before making the final version.
How long can the driving performance be?
Use one continuous clip between 3 and 30 seconds. Some model or orientation settings can impose a shorter active limit, which the form shows before generation.
What kind of character image works best?
Use one clearly visible, human-like character with a readable face and body framing similar to the performer. Portraits, mascots, illustrations, anime characters, and stylized renders can work, but no style or character type is guaranteed.
Do I need a motion-capture suit, markers, or a rig?
No. A normal phone, webcam, or uploaded video provides the performance reference. No tracking suit, markers, pre-rigged skeleton, or manual keyframes are required for the finished video workflow.
Is this real-time performance capture?
No. You record or upload a take and then wait for the model to generate the video. The page does not drive a live avatar, virtual camera, or real-time puppet.
Is the generated movement an exact frame-by-frame copy?
No. The model uses the take as creative and motion guidance. Timing and major actions can carry across, while small fingers, fast motion, facial detail, identity, and background elements can be reinterpreted.
Can I capture multiple performers in one clip?
Use one clear performer. Multiple people, overlaps, or competing faces make it difficult for the model to determine which performance should control the character.
What happens if the face or hands leave the frame?
Hidden or off-screen details may be simplified, interpolated, or become unstable when they return. Keep the face and important gestures visible, especially at the start of the clip.
How is this different from lip sync or a talking avatar?
Lip-sync tools mainly animate the mouth and sometimes the face from audio. AI Performance Capture uses a recorded acting take to guide the wider delivery, including pauses, reactions, head motion, posture, and visible gestures.
What is the difference between Performance Capture and Motion Control AI?
Motion Control AI can use any suitable reference video. Performance capture is the actor-led workflow: you record the complete take you want the character to follow. Both use the same generation platform, but they serve different creative entry points.
Can I use AI Performance Capture on mobile?
Yes. Compatible mobile browsers can record directly, while other devices open the native camera. When the native camera opens, record or select a 3–30 second clip because the webpage cannot automatically stop the device camera for you.
Can I control the background or upload a character video?
Kling 3.0 can let either the performance video or character image guide the generated background. The current character input is a still image, not a character video, and background details can still change during generation.

AI Performance Capture for Actor-Led Character Video

AI Performance Capture turns a short recorded acting take and a character image into a generated character video without a mocap suit, markers, rigging, or manual keyframes. Record or upload one continuous 3–30 second performance, keep the face and important gestures visible, then use a 720p preview to evaluate timing, expression, identity, hands, lip sync, and background before creating a 1080p version. Unlike AI motion capture or markerless mocap tools that export FBX, BVH, GLB, or 3D skeleton data, this actor-led Motion Control AI workflow produces a rendered video for presenters, dialogue, reaction clips, interviews, music performance concepts, and brand mascots.
