The Keyer node accepts front, back, and matte clips as input. Select an output type from the Select Output box.

NoteThe Keyer node does not support 16-bit floating point (OpenEXR) input. It must first be attached to a LUT Editor node to convert it to a bit depth of 8, 10, or 12. Depending on the dynamic range of the media, this conversion may affect details, especially in the highlights. See LUT Editor Node and Accessing the LUT Editor in Batch . Use floating point input with the Keyer Channel, Keyer HLS, Keyer Luma, Keyer RGB, Keyer RGBCMYL, or Keyer YUV node to generate a 16-bit key clip.

The Keyer node processes gaps in clips set to No Media based on the input tab receiving the information.

Input | Result
--- | ---
Front | No media
Back | Black frames
Matte | Black frames

When working in the Keyer module, missing media in front clips set to No Media are converted into black frames while they are in the editor. When missing media is output from the Keyer node, it returns to a No Media state.
