THE INVADERS TV Series: Hollywood tricks used to make the Invaders burn up when they died

I'm a retired film editor, but I loved THE INVADERS as a kid...especially the wonderful special effects. Quinn Martin didn't skimp on budgets, and this included the optical effects. According to Roy Thinnes, each "immolation" cost about $190-210 which, in 2024 dollars, is about $1800. That made each optical quite expensive, because it involved frame-by-frame rotoscoping, animation cameras, and optical printers. But the results are gorgeous--and haunting. I do not own any of this footage. I'm presenting here for educational and film/tv history purposes.
