What is LUT?
Short answer
A LUT, or look-up table, is a file that maps input colours to output colours, so you can apply a colour look or convert between colour spaces in one step. Creative LUTs give a style, and technical LUTs convert footage. They are a starting point, and exposure still needs adjusting.
How is LUT used in editing?
Editors apply a LUT to footage to get a graded look quickly, then tweak exposure and white balance underneath it.
What mistakes do people make?
- Applying a LUT to badly exposed footage
- Using the wrong colour space
- Leaving it at full strength
Do skills use LUTs?
SkilledCut skills apply their own looks. For example, Glass colour-grades the room with a violet glow. For precise colour work, grade the render in a colour-focused editor.
Frequently asked questions
What does LUT stand for?
LUT stands for look-up table, a file that maps each input colour to a new output colour to apply a look or convert colour spaces.
Is a LUT the same as a filter?
Similar, but LUTs are precise files.
Can I use a LUT on phone footage?
Yes, with matching settings.
Should I always use one?
No. Use a LUT when it suits the footage, and reduce its strength or skip it if it harms skin tones or exposure.
