Recap:

  • @nick showed a realtime setup hooked up to the video conference! Blackmagic Film log image from a Pocket 4K camera passed through two versions of an ACES Rec. 709 LUT, one with gamut mapping, one without. Lit by small RGB LED light. Check out the first few minutes of the recording!
  • Re: compression curve modification:
    • Have options (1.2, 1.1, 1.0, etc)
    • More images and fewer options
  • Scott looking into options for Dropbox download limitations, will need to be smart about user testing packages (sub 5gb)
