This is a faq page about chroma key, which is available with Vision Mixer SDK, Video Mixer DirectShow Filter or the Chroma Key DirectShow Filter.

Your need to do the next:

  1. Add first (background) video (the file or live input).
  2. Add second (keying) video.
  3. Add the second video to mixing. "Add Rect", right click on preview input video (small), right click on video output (big). Now only the second video is visible.
  4. Specify the chroma-key:
    • Select the second video input (the top list, see the screenshot).
  5. Specify the HLS or RGB chroma-key.
