BEFORE YOU START
Before you start
Open the track editor with an avatar already added. With multiple presenters, identify the intended avatar track. Make sure its avatar clip covers the interval where you want the motion.
Screenshots show actual sample projects. Your interface may vary with your plan and updates. Instructions describe desktop browser operation; this guide can also be read on a phone.
Choose the avatar and start time
First decide who should move and when.
- Click the avatar track name on the left: ava_1 in this example.
- Click the time ruler to move the playhead to the intended start.
- Click Head motion in the toolbar.
- Action Click the avatar track name on the left: ava_1 in this example.
- Action Click the time ruler to move the playhead to the intended start.
- Action Click Head motion in the toolbar.
Check If a tool is hidden, check » at the toolbar’s right edge. Recheck the selected avatar before adding it.
Preview and insert a head motion
Select a motion in the list to review its movement and duration.
- Select a motion such as Gentle nod and inspect the sample on the right.
- Click Import to track to add it to the selected avatar’s Head motion track.
- Action Select a motion such as Gentle nod and inspect the sample on the right.
- Action Click Import to track to add it to the selected avatar’s Head motion track.
Check Check the start after insertion: existing motions may shift the insertion to a free interval. Left and right are from the viewer’s perspective.
Adjust a nod’s intensity and duration
Click the new head-motion clip to open its settings on the right.
- Check the Type and adjust Strength. 1.0 is standard; reduce it if the motion feels exaggerated.
- For nods or backchannels, enable Slight variation by scene when appropriate.
- Adjust Duration. Use Fit the full motion to restore the suggested duration.
- Enter Check the Type and adjust Strength. 1.0 is standard; reduce it if the motion feels exaggerated.
- Action For nods or backchannels, enable Slight variation by scene when appropriate.
- Enter Adjust Duration. Use Fit the full motion to restore the suggested duration.
- About motion variation
- A saved variation does not randomly change on every generation. Use Try another motion when you want a different variation.
Check Shortening truncates the later movement; changing duration does not speed up or loop it. Fixed-duration motions cannot be resized.
Set the angle and transition timing
Choose a type such as Look up to reveal angle-based controls.
- Choose Type and Strength; this example uses Look up.
- Enter a Target angle. A blank field uses the type’s default, multiplied by Strength. Restore default clears the override.
- Rise controls the approach; Fall controls the return. Duration sets the overall interval.

Check Use Base gaze for eye direction and Base expression for facial expression, separately from the head movement.
Generate and review the movement
Review these settings after updating the avatar preview video.
- Select Generate ungenerated clips in the toolbar.
- Wait until the avatar clip says Preview generated. You can follow progress in Generation jobs at the bottom.
- Action Click Generate ungenerated clips.
- Check After generation, the avatar clip will say Preview generated.
Check Once the voice and expression are ready, generate pending previews and play through the reaction and its surroundings. Check its timing, mouth movement and transition to the next moment. A still image cannot show the finished motion.
BEFORE YOU FINISH
One final check.
