What is a DPX file?

A DPX file is a raster image saved in the Digital Picture Exchange (DPX) format, which is primarily used for transferring film images to a digital medium without losing quality. It may contain a single frame but is typically exported as a frame sequence with a series of still images.

Kodak originally developed the DPX format, also referred to as the "Digital Moving Picture Exchange Bitmap." However, the Society of Motion Picture and Television Engineers (SMPTE), a member of the American National Standards Institute (ANSI), enhanced and published the DPX format. As a result, SMPTE now maintains the file format.

SMPTE released version 1 of the DPX format in 1994 and version 2 in 2003. In 2004, the Motion Picture, Broadcasting, and Recorded Sound Division began using the DPX format for scanning motion pictures for theatrical distribution.

More information about the DPX format

DPX is based on Kodak Cineon (.CIN), the original Kodak digital image format. The difference between DPX and CIN files is that DPX files contain additional information in the file header.

The DPX format consists of four sections with one optional section (user-defined data):

  • Generic image data - Includes information about the file, image, and image orientation
  • Industry specific information - Includes motion picture film and television information that describes the source the image data comes from (film and camera)
  • User-defined data (optional) - Includes customized information typically populated by third-party applications to define technical specifications that deviate from the standard
  • Image data - Includes bitmap pixel data stored as an array of 32-bit elements

How to open a DPX file

You can open DPX images with various applications, such as ImageMagick (multiplatform), XnViewMP (multiplatform), and Apple Final Cut Pro (macOS). You can also open DPX images with Adobe SpeedGrade in Windows and macOS, but it has been discontinued.

How to convert a DPX file

Several image editors and viewers, including XnViewMP and ImageMagick, can convert DPX images to other formats.

For example, XnViewMP converts DPX images to many file types, including the following formats:

  • .JPG - JPEG Image
  • .PNG - Portable Network Graphic
  • .BMP - Bitmap Image
  • .WEBP - WebP Image
  • .TIF - Tagged Image File Format
  • .PGM - Portable Gray Map Image
  • .DDS - DirectDraw Surface Image
  • .PDF - Portable Document Format
