About DPX to JPG Conversion
DPX (Digital Picture Exchange) is the SMPTE 268M standard for digital cinema, carrying 10-bit or 16-bit per channel image data with logarithmic Cineon color encoding. DPX is the interchange format between film scanners, color grading suites (DaVinci Resolve, Baselight), VFX compositing applications (Nuke, Flame), and digital intermediate (DI) facilities. JPG is the universal lossy image format viewable on every computing device.
Converting DPX to JPG produces compact, universally viewable stills from cinema-grade source material. This conversion is essential for extracting frame stills from film scans for marketing (poster art, key art), editorial (press kits, reviews), production documentation (continuity photos, VFX breakdown frames), and personal portfolios. The JPG output can be opened, shared, and published anywhere.
Why Convert DPX to JPG?
Film productions need shareable frame grabs for dozens of non-technical purposes. Marketing departments need stills for social media, trade publications, and festival submissions. Editors need reference frames for cut lists. Continuity supervisors need frame documentation. VFX artists need portfolio stills. All of these use cases require a format that opens on any device — JPG is that format. A 30 MB DPX frame becomes a 500 KB to 2 MB JPG that can be emailed, uploaded, and embedded anywhere.
DPX viewer software (Nuke, RV, DJV) is expensive and requires significant system resources. Converting key frames to JPG enables anyone in the production — producers, accountants, legal teams, marketing coordinators — to view film content without VFX software licenses. This democratizes access to film imagery across the production.
Common Use Cases
- Extract key frame stills from DPX film scans for marketing materials and press kits
- Create JPG reference frames from DPX dailies for editorial cut list documentation
- Produce portfolio-quality stills from DPX VFX composites for artist showreels
- Generate JPG continuity photos from DPX film scan sequences for script supervisors
- Convert DPX frames to JPG for submission to film festivals and awards campaigns
How It Works
The DPX file header is parsed for image dimensions, bit depth, and color encoding type (logarithmic or linear). ImageMagick applies the appropriate log-to-linear conversion using a Cineon-to-sRGB LUT, then tone-maps the high-bit-depth source (10/16-bit) to 8-bit per channel. The 8-bit RGB data is JPEG-compressed with configurable quality (default 92 for production stills). Color space is set to sRGB for accurate display on consumer devices. The output preserves the full spatial resolution of the DPX frame unless resizing is requested.
Quality & Performance
The conversion combines two quality-affecting transformations: (1) log-to-linear color space conversion with bit depth reduction (10/16-bit to 8-bit), which compresses the source's dynamic range; and (2) JPEG lossy compression, which introduces minor DCT artifacts. At JPG quality 92+, the JPEG artifacts are imperceptible. The log-to-linear conversion is the more significant quality factor — using a proper film stock LUT rather than the generic Cineon curve produces more faithful results. At full spatial resolution (2K or 4K), the output is suitable for large-format printing.

Tips for Best Results
- 1Apply a proper LUT (Log-to-Rec.709 or film stock emulation) for color-accurate output rather than relying on the generic Cineon transform
- 2Use quality 92-95 for marketing stills and festival submissions
- 3Include frame numbers in filenames when converting sequences for traceability
- 4For 4K output, the JPG is 2-5 MB — compact enough for email and web while retaining cinema resolution
- 5Color-grade in DaVinci Resolve or Nuke before exporting to JPG for the highest-quality production stills
DPX to JPG conversion produces universally shareable stills from cinema-grade film data. The output is suitable for marketing, documentation, portfolios, and any use case where DPX viewer software is not available.
