Motion Sync drives an avatar with the movement from a video you supply. Upload or record a clip as the motion source, pick the avatar image, and the avatar performs the same movement. Open it at app.percify.io/home/motionSync.
The Percify Motion Sync screen with Upload Video as step one, Pick Your Avatar as step two, the result on the right and a model panel showing the per second credit rate

Three steps left to right: the motion source, the avatar, and the result. The panel prices the run per second before you generate.

​
How to run one

  1. Step 1 Upload a video as the motion source, or press Record to capture one.
  2. Step 2 Upload the avatar image that should perform the motion.
  3. Pick the model. Kling 2.6 Standard runs at 7 credits per second.
  4. Press Generate. The panel shows Rate, Duration and Total, so the price is settled before the run starts.
Because it is priced per second of the source video, the length of the clip you upload is what decides the cost.

​
What works best

The tips on the page are worth following:
  • One person, clearly lit.
  • Full body or upper body in frame.
  • 5 to 30 second clips work best.
A crowded frame gives the model more than one body to track, and a very long clip multiplies the cost without improving the result.
