DPX (Digital Picture Exchange) is the SMPTE 268M standard for digital cinema, encoding film scan data at 10-bit or 16-bit depth with logarithmic color for maximum dynamic range capture. DPX is the interchange format for the entire post-production chain — from film scanners to color grading, VFX compositing, and digital intermediate output. PDF (Portable Document Format) is the universal document standard for professional distribution.
Converting DPX to PDF creates shareable, printable documents from cinema-grade frame data. This conversion is critical for film production documentation: shot reports, VFX progress books, color grading reference sheets, and festival submission packages all require PDF format. The PDF output embeds the DPX frame (after color space conversion) in a document that anyone can open, print, and annotate.
Film production generates massive documentation requirements. Daily shot reports with frame references, VFX progress books showing composite evolution, color reference books for consistency checks, and marketing lookbooks all need to be distributed as PDF. Converting DPX frames to PDF embeds these cinema-grade stills in the format that production offices, studio executives, festival programmers, and press contacts all expect to receive.
PDF's print capabilities make it the format for physical output from DPX source material. Poster proofs, exhibition prints, book layouts, and press kit sheets all start with DPX frames converted to high-resolution PDF. The PDF carries the color-corrected image at full resolution with proper page sizing, margins, and metadata for professional reproduction.
The DPX header is parsed for image dimensions, bit depth, and color encoding. Log-to-linear conversion is applied using a Cineon-to-sRGB LUT, and the image is tone-mapped to 8-bit per channel. The converted image is embedded in a PDF page sized to match the image dimensions at the specified DPI (default 300 DPI for print-quality output, 150 DPI for screen viewing). The image data is compressed within the PDF using FlateDecode (lossless) or DCTDecode (JPEG, for smaller files). PDF metadata fields (title, author, keywords) can be populated for cataloging.
The log-to-linear color conversion is the primary quality factor. A proper film stock LUT produces accurate tonal reproduction; the generic Cineon curve provides acceptable but less precise results. The 10/16-bit to 8-bit reduction compresses the source's dynamic range. Within the PDF, lossless embedding preserves the converted image perfectly, while JPEG embedding introduces minor lossy compression. For print output at 300 DPI, a 2K DPX frame produces a ~7x5 inch print area — sufficient for most documentation purposes. 4K frames provide larger or higher-resolution output.
