FCP Levels & Gamma Conventions e.g. for Stills

Things To Remember [http://www.kenstone.net/fcp_homepage/video_levels_nattress.html]

  • Still images are RGB in a 0 to 255 range
  • Levels above 100% FCP, 100 IRE or code 235 are called “super white”
  • Final Cut Pro automatically converts images to fit into the 0% FCP to 100% FCP range when it is set to “White”.
  • Final Cut Pro automatically converts images to fit into the 0% FCP to 100% FCP range when it is set to “Super White”.
  • Final Cut Pro only looks at the 0% FCP to 100% FCP range upon still image export, and maps this range to 0 to 255 RGB.
  • Picture information can be lost on still image export if you have picture information in the 100% FCP to 110% FCP range.
  • Final Cut Pro always applies a gamma correction of about 0.8 to imported still images. If necessary, this can be corrected by applying a gamma correction of 1.2 in Final Cut Pro or 0.8 in Photoshop.
  • Don’t preempt Final Cut Pro’s conversion of still images by setting your blacks in Photoshop to 16 and whites to 235. Final Cut Pro expects you to use the full 0 to 255 RGB range.
  • “White” and “super white” settings only effect the import of still images.
  • “White” and “super white” settings do not effect video or video rendering.
