Umbrella term for all calibration and normalization steps between camera and delivery — LUT application, color space conversion, metadata interpretation. Essential in DCP workflow for color-accurate output.
Processing is not simply color correction—it's the systematic translation of your camera's raw data into a standardized output format. On set or in the edit, this usually happens invisibly, but without clean processing, you'll end up with color shifts, incorrect contrast, or inconsistent metadata in the cinema or for streaming. The core problem: every camera, every monitor, every DCP system operates in different color spaces. Processing bridges this gap.
In practice, this means: You have camera-native footage—say, Red RAW or Alexa LogC. This raw data is linear, mathematically precise, but unusable for the human eye (it looks like a gray mush). Now comes the first layer of processing: the LUT application (Look-Up Table). A LUT is a mathematical lookup table that maps each input pixel value to an output value—typically: LogC → Rec.709 or DCI-P3. This is followed by color space conversion: you transform from the native camera interpretation into the target space (cinema: DCI-P3, streaming: Rec.2020 or Rec.709). In parallel, gamma adjustment occurs—the brightness curve must be calibrated for the human eye.
The next level is metadata interpretation. Each clip stores information: white point, exposure index, gamma curve, color primaries. The editing suite must interpret this to respect the DoP's intent. Done incorrectly: your colorist works on an uncalibrated monitor image and produces a DCP that looks completely different in the cinema. Done correctly: every monitor in the pipeline—editing suite, colorist suite, DCP mastering room—displays the same image because all use the same processing steps.
In the DCP workflow, processing is not optional—it's part of the technical spec. Your master file must be converted to the correct color space, with the right JPEG2000 compression settings. Digital cinemas also require standardized processing: DCPs in Rec.709 (for 2K/4K Digital Intermediate), calibrated to the D65 standard and a screen luminance of approx. 16 foot-lamberts. Without this normalization: Image A looks different in cinema XY than in cinema XZ. Processing eliminates this variability—or at least reduces it to an acceptable level.
