About .cube Files
CUBE files are plain text files that store Lookup Tables (LUTs) for color grading.
They contain numerical data used to remap color values in images and videos. This makes them vital for achieving consistent color correction in media workflows.
- Main use case: Applying precise color adjustments in film, photography, and video editing.
- Format details: Being stored as text/plain files, they can be opened and edited with any text editor while also supporting rem (remark) comments.
- Compatible software: Professional applications like Adobe Premiere Pro, DaVinci Resolve, and Adobe Photoshop support these files.
Relationship between file extension and MIME type
A file extension is a suffix at the end of a filename that indicates what type of file it is. File extensions help both users and operating systems identify what application should be used to open the file.
File extensions are typically separated from the filename by a period (dot) and consist of 2-4 characters, though they can be longer. For example, in the filename "document.pdf", ".pdf" is the file extension.
File extensions are closely related to MIME types, as they both serve to identify the format of a file. However, while MIME types are used primarily by web browsers and servers, file extensions are used by operating systems and applications.

FAQs
What is a .cube file used for?
A .cube file is a standard 3D Lookup Table (LUT) used to apply color correction or color grading to images and video. It contains a mathematical grid of numbers that software like DaVinci Resolve or Adobe Photoshop uses to map input colors to specific output colors, creating a stylized "look."
How do I open a .cube file?
If you want to view the raw data, you can open a .cube file with any text editor, such as Notepad or TextEdit, because the underlying format is text/plain. To actually apply the color grade, you must import the file into video editing software like Adobe Premiere Pro or Final Cut Pro.
How do I use a .cube LUT in Adobe Premiere Pro?
To apply a .cube file in Premiere Pro, open the Lumetri Color panel. In the "Basic Correction" section, click the dropdown menu next to "Input LUT," select Browse, and navigate to your .cube file to apply the effect to your footage.
Can I convert .cube files to other formats?
Yes, .cube files can be converted to other 3D LUT formats like .3dl, .look, or .icc using specialized utilities such as LutCalc or IWLTBAP LUT Generator. This is often necessary when moving assets between different editing suites or hardware monitors.
Why does my .cube file look like text?
The .cube format is text-based to ensure cross-platform compatibility. It consists of a header defining the LUT size and a long list of floating-point numbers representing RGB values. You can learn more about text-based formats at mime-type.com.
Are .cube files safe to open?
Yes, .cube files are generally safe because they are simple text files containing data, not executable code. However, you should always ensure you download assets from reputable sources to avoid files that may have been renamed or spoofed.
General FAQ
What is a MIME type?
A MIME (Multipurpose Internet Mail Extensions) type is a standard that indicates the nature and format of a document, file, or assortment of bytes. MIME types are defined and standardized in IETF's RFC 6838.
MIME types are important because they help browsers and servers understand how to process a file. When a browser receives a file from a server, it uses the MIME type to determine how to display or handle the content, whether it's an image to display, a PDF to open in a viewer, or a video to play.
MIME types consist of a type and a subtype, separated by a slash (e.g., text/html, image/jpeg, application/pdf). Some MIME types also include optional parameters.
How do I find the MIME type for a file?
You can check the file extension or use a file identification tool such as file --mime-type on the command line. Many programming languages also provide libraries to detect MIME types.
Why can one extension have multiple MIME types?
Different programs and historical usage may assign various MIME identifiers to the same file format. Listing them together helps maintain compatibility across tools.
