01In plain English
A look-up table maps every colour in a clip to a new one. Camera makers publish LUTs that convert flat log footage into normal colours, and colourists share creative LUTs that apply a film look in a click.
02Why it matters when you are choosing
LUTs save time and keep a look consistent across a project. If you shoot log footage, you will need an editor that loads them.
03What to check
Ask the vendor
Check that the editor can import standard LUT files and apply them to one clip or the whole timeline.
