Dolby Vision Metadata Inspector

Per-shot luminance metadata: L_min (minimum), L_mid (average), L_max (peak), all encoded as PQ values (0–1). Required — drives the base tone-map for every display. Appears on all shots.

Per-display, per-shot tone-map corrections: Lift, Gain, Gamma, Saturation, Hue, ToneMapMax, ToneMapMin. One L2 block per target display ID (TID). Allows the colorist to customize the creative look for a specific target display.

Per-shot refinements applied on top of L1: highlight offset, midtone offset, shadow offset. Used when the L1 values need fine-tuned correction for a particular shot without changing the mastered L1.

Defines a new target display inline within the shot metadata (peak brightness, minimum brightness, diagonal size). Alternative to declaring target displays in the file header. Rarely used in modern workflows.

Canvas aspect ratio and image aspect ratio. Defines the active image area within the canvas frame (e.g., letterbox / pillarbox bars). Essential for widescreen or anamorphic content where the active picture doesn't fill the full container.

Maximum Content Light Level (brightest single pixel across all frames) and Maximum Frame-Average Light Level, both in nits. Composition-wide values used by non-DV HDR processing paths (e.g., HDR10 fallback). Highly recommended for broad device compatibility.

Enhanced per-display color and tone-map control beyond L2. Includes T0–T5 trim values, MidContrastBias, HighlightClipping, and per-axis SaturationVectorField / HueVectorField for granular creative adjustments on a specific target display.

Extended colorimetry for a custom target display: white point chromaticity, primary chromaticities. Allows precise description of displays whose color volume falls outside standard presets.

Additional colorimetry data for the custom mastering display, paralleling L9 for the source/mastering side. Used when the mastering display uses non-standard primaries or white point.

Describes the content's intended viewing environment and reference mode: content type (cinema, home, etc.), white point luminance, and reference mode (cinema projector, home monitor, etc.). Helps the display device select the appropriate rendering pipeline.

Vendor-defined extension data block for proprietary metadata not covered by the standard levels.
