6. Avatar Performance Control

Take full control of the avatar’s performance in your video, making their actions more dynamic and natural.

6.1 Add Custom Motions

Add custom motion shots to your text content, ensuring the avatar’s actions suit the scene and enhance expressiveness.

How to Add:

Go to the 3D Generate page and select the position where you want to add a motion.
Click the Advanced Editing - Motion button in the toolbar to open the motion library.
Browse the motion library by category and select the appropriate motion for your content. Click a motion to add it to your text segment.
To change or remove a motion, reopen the motion library from the motion tag position. Click Delete or the Remove button in the bottom right corner to delete the motion.

6.2 Customize Walk Frequency

In certain scenarios, the system will make the avatar walk on stage. You can customize the walk frequency or disable this effect as needed.

Factors Affecting Walk Effect:

Scene: Large stage and small stage scenes support walking actions; other scenes do not.
Media:
- If you use video media, the system assumes you want to focus on the video content, so walk effects won’t trigger. To enable walking, replace the video with an image.
- Pure text scripts longer than 30 seconds are more likely to trigger walking.
Frequency: Higher walk frequency settings increase the chance of walking actions.

How to Adjust:

To adjust walk frequency, click the [Motion] button in the toolbar. Find the walk frequency setting at the bottom of the motion library and choose the desired level.
To disable walking, simply turn off the walk effect on this page.
Ensure enough distance between different motions. If motions are placed too close together, some actions may not work as intended. Adjust your script to keep adequate spacing between motions for best results.

Ⅴ. Special Features

Allows you to insert pause markers within the text. When the audio reaches a pause marker, playback will stop until the specified duration has finished.
Batch Phonetic Annotation
Enables you to add correct pronunciations to text, with the option to annotate multiple words at once.
