  Posted by Erez Schwarzbaum on May 27, 2013 at 7:42 pm

  Hello ALL
  I’m keying a log-c footage from arri alexa

  I made it very good by applying a color lut but i need to send back a log-c.
  that was my work Flow:
  precomp of the green screen shot,
  cleared all
  than when i apply the trcmate on a untouched footage it dose not give me a good result and i have a green edges.
  any ideas?

  Keylight performs better with Rec 709/601 or P3 footage. Color correct first, apply keylight, and then use the resulting alpha channel on the original log-c footage. You’ll find you’ll usually get better results.
