Tips for Using the "Generate Facial Data File"

YanusLIVE v1.2.5

It is recommended to check the following three parameter settings under the Settings > Experimental tab:

• butterworth_cutoff: 5

• process_csv: IMAGE

• filter_type_csv: BUTTERWORTH

  
  

These are the default settings.

To verify while playing the video file, similar to setting up the CSV file generation:

1. Go to Settings > Live and select process_file as IMAGE.

2. Under Settings > Experimental, set filter_type_live to BUTTERWORTH.

3. Click Apply.

4. Restart the Actor mode by stopping and then playing again to apply the changes to process_file.

5. Changes to filter_type_live and butterworth_cutoff will be applied immediately if you click Apply during playback.

For faster response times, it is recommended to set the Cutoff Frequency to 9.

If there is a lot of noise, a setting of 5 is recommended.

By following these tips, you can ensure optimal performance and accuracy when generating facial data files.

"Generate Facial Data File" Window Not Appearing Issue

YanusLIVE v1.2.5

If the paths to the video and Actor Profile files contain non-English characters or spaces, this issue may occur. Additionally, there have been cases where this issue occurred while using the OBS program simultaneously. The path of the YanusLIVE program itself also needs to be checked.

This is because the path of default_actor_profile.json follows the execution path of YanusLIVE.

Simpler paths such as the following are recommended: Here are examples of the paths:

D:/YanusSTUDIO/YanusLIVE/demo

D:/YanusSTUDIO/YanusLIVE/package/Bora

D:/YanusSTUDIO/YanusLIVE/YanusLIVE_v1.2.5 Examples of paths to avoid

• User directories (e.g., C:/Users/Username/)

• Program Files (e.g., C:/Program Files/)

• OneDrive directories (e.g., C:/Users/Username/OneDrive/)
