How do I apply multiple chroma key samples in CyberLink PowerDirector 365?

PowerDirector supports applying up to 3 chroma key samples in one single video in the Advanced Editing panel. To use multiple chroma key samples, do this:

1.  Click on the target video on the timeline > Edit > Chroma Key, and the Advanced Editing window will open.
2. Use the color picker to pick a color as the first chroma key sample.
3. Click on the "Add New Key" button to add the second chroma key sample by the same way.
