About .cdl Files
CDL files are plain text files that store color correction data used in video and film post-production.
They follow the American Society of Cinematographers' Color Decision List (ASC CDL) standard, which is a set of guidelines for applying consistent color changes.
The file contains numeric values for adjustments like slope, offset, power, and saturation, enabling precise color grading.
Because they use the MIME type text/plain, you can open them in any basic text editor, though they are mainly processed by specialized color grading software.
- Main Use: Exchanging color adjustments between different grading systems.
- Practical Functionality: Embedding color decisions in a standardized text format.
- Common Software: Applications such as DaVinci Resolve, Baselight, and Adobe Premiere.
- MIME Type: text/plain, indicating human-readable content.
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 CDL file used for?
A .cdl file is an ASC Color Decision List used in video post-production to transfer primary color grading information between different software systems. It stores numeric values for Slope, Offset, Power, and Saturation in a standard XML-based text format.
How do I open a CDL file?
Because CDL files are formatted as plain text, you can view the raw data using any text editor like Notepad or TextEdit. However, to apply the color grading instructions to video footage, you must import the file into professional software like DaVinci Resolve, Avid Media Composer, or Adobe Premiere Pro.
Can I convert a CDL file to a LUT?
Yes, you can convert a CDL file into a 3D LUT (such as a .cube file) using color management tools like Lattice or by exporting a LUT from DaVinci Resolve. This is useful if your target display or software supports standard LUTs but not the specific ASC CDL format.
What is the correct MIME type for CDL files?
Since these files contain human-readable characters, they typically utilize the MIME type text/plain or sometimes text/xml. You can verify more details about text-based media types at mime-type.com.
Why does my CDL file look like code when opened?
The file contains XML tags defining color parameters (SOP and Saturation), which is meant to be read by software rather than humans. If you see tags like <Slope> or <Offset>, the file is not corrupted; you are simply viewing the raw data structure in a text editor.
What is the difference between a CDL and a 3D LUT?
A CDL is strictly for primary color corrections (basic adjustments to balance the image) and remains editable. A 3D LUT can contain complex, non-linear color transformations but is usually a "baked" table of values that cannot be easily adjusted after creation.
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.
