DPX

Digital Moving-Picture Exchange

Data type	Image
MIME type	image/dpx
Developer	SMPTE (Society of Motion Picture and Television Engineers)
Primary use cases	Film scanning (frame sequences), digital intermediate mastering, VFX plates, archival masters for moving-image workflows

What is the DPX file format?

DPX is a professional raster image format used in film scanning and post-production as a high-quality frame-based interchange.

DPX file characteristics

Data type	Image
MIME type	image/dpx
Compression	None (typical) or optional lossless RLE
Color depth	Varies by workflow; commonly 10-bit log (film scanning) or 16-bit per channel linear for mastering; implementations may support higher bit depths
Color space	Commonly RGB; may also be YCbCr/YUV and other encodings depending on header metadata
Transparency support	Yes
Animation support	No
Metadata	Self-describing binary headers with core fields (dimensions, bit depth, packing/encoding, transfer/colorimetric specs, offsets), plus industry-specific fields; user-defined section can carry arbitrary binary data; some variants can include XML
Standard / Specification	SMPTE ST 268-1 and SMPTE ST 268-2 (DPX); originally standardized as SMPTE 268M:1994
Typical file size	Highly variable. Uncompressed sizes are typically tens of MB per 2K/4K frame; sequences can quickly reach hundreds of GB or more
Year introduced	1994

Advantages

The DPX file format offers several advantages that make it suitable for common use cases.

Designed for high-quality frame exchange;
Rich technical header metadata;
Widely used in professional film/VFX pipelines;
Supports multiple bit depths/encodings;
Optional lossless RLE

Limitations

The DPX file format has certain limitations that may affect its use in specific scenarios.

Frame-per-file workflows require consistent naming and storage management;
Color management depends on correct interpretation of transfer/colorimetric metadata;
No built-in encryption/authentication—must be handled externally

Compatibility

DPX images are widely supported and can be viewed on most devices and platforms.

Supported platforms: Cross-platform in professional media tools; common on Windows/macOS/Linux in VFX/DI pipelines
Supported devices: Film scanners, post-production workstations, render/encode nodes
Browser support: No
Mobile support: No
Backward compatibility: Yes

Security considerations

Treat as untrusted binary input: user-defined header can contain arbitrary binary blobs and some variants can embed XML; DPX allows RLE so decoders need strict bounds checks; no integral encryption/authentication (an encryption-key field exists but no standard algorithm is defined)

License

Open SMPTE standard; no licensing/patent restrictions noted by the Library of Congress

DPX (Digital Moving-Picture Exchange) is a SMPTE standardized, frame-per-file raster format widely used for film scanning, digital intermediate, and VFX pipelines. It stores image data plus a binary header with core technical fields and industry-specific metadata; variants differ by pixel packing, padding, transfer characteristics (e.g., log/linear), and color encodings.
