LUT (Look-Up Table)
ما هو LUT (Look-Up Table)؟
A LUT is a preset colour filter for video: a file that transforms the colours of footage to apply a specific look, like a vintage film grade or a cinematic colour treatment, instantly and consistently across all your clips.

كيف يُقارن
Compared with related concepts
LUTs differ from manual colour grading in that they apply a predefined, fixed colour transformation rather than a set of adjustable parameters. Manual grading using lift/gamma/gain, curves, and hue/saturation controls gives the colourist full flexibility to adjust every aspect of the grade. A LUT encodes a specific set of those adjustments into a non-interactive transformation. In practice, LUTs are often used as a starting point ( a base look applied quickly ) with manual adjustments applied on top to fine-tune for specific shots or conditions.
فكّر فيه كأنه…
A LUT is like a photographic filter for video: instead of manually adjusting colour controls for every clip, you slip one filter over the lens and all the footage gets the same colour treatment automatically. The filter's formula never changes; it simply transforms whatever light passes through it the same way every time.
نصيحة احترافية
When applying LUTs to AI-generated footage in post-production, pay attention to the intensity of the transformation. LUTs designed for log-encoded camera footage applied to AI-generated content ( which typically has a different baseline colour response ) may produce unexpected results. Starting with the LUT at reduced strength and blending with the original, or choosing creative LUTs designed for display-ready footage, typically produces more predictable and controlled results.
الأنواع والاختلافات
- LUT types include 1D LUTs, which adjust only brightness and contrast values independently per channel; 3D LUTs, which map colour values in full three-dimensional colour space and can apply much more complex transformations including hue shifts and cross-channel adjustments; technical LUTs for colour space conversion; and creative LUTs for aesthetic look application.
- Creative LUT categories include film stock emulations, broadcast-standard technical looks, brand-specific looks for productions or networks, and community-developed stylistic presets.

LUTs are used to convert log-encoded camera footage to display-ready formats for monitoring during production, to apply cinematic colour grades efficiently across large amounts of footage in post-production, to match AI-generated video footage to the colour style of a live-action production, to apply brand-consistent visual looks across social media and marketing content, and to share a carefully crafted colour grade between productions, collaborators, or platforms in a portable, software-agnostic format.
