Demo summary

The creator adjusts the audio scale for expressiveness, adds a descriptive prompt for movement style, and configures the One Video Sampler steps before running the final generation.

Step-by-step

Adjust the audio scale to control movement intensity and lip sync expressiveness
Enter a minimal description of the scene in the prompt box
Configure the steps value in the One Video Sampler
Click run to generate the video

Options

Set steps to 6 for faster generation speed
Set steps to 10 or higher for better quality and more exaggerated body movements

Watch out for

Increasing the steps value may introduce artifacts or unnatural body movements
Higher step counts result in longer generation times

Tips

Keep the prompt minimal, focusing on a natural description of the action
Leave the audio scale at the default of 1 unless more intense movement is needed
