Dean used WaveFilter Image to generate a "chromakey" matte of frame 105 using its interactive Color Range selector to "white out" the blue. Sequence further batch processed in a paint box to deinterlace each frame and blur the matte edges to help reduce NTSC video artifact noise. A white border also added to cover up NTSC video border garbage for a clean polygon clipmap edge.
Raw NTSC video frame 105 of talent in front
of a properly lit chromakey blue curtain.
Final LightWave composite using the "SK-key" image sequence as a planar clipmap on a 3:4 aspect ratio polygon surfaced with the "SK-img" sequence (which was also deinterlaced).
WaveFilter Image’s new Edge Blend-Alpha Edges Only used in Selected Surface Mode (surface special buffer set to 255). Luminousity set to 30% and Diffuse to 70% to adjust receive shadow density. Deinterlacing the video and matte was required since Dithered Motion Blur (field rendering thus disabled) was the desired rendering method. Low AA rendered with a
second WaveFilter Image set to preset High AA
and Four Pass Preference.
