Convert DPX to PJPEG

The DPX (Digital Picture Exchange) 2.0 file format is a widely adopted standard for exchanging high-quality, resolution-independent, pixel-based images, primarily used in the film and post-production industries. Developed by the Society of Motion Picture and Television Engineers (SMPTE), DPX files store individual frames of scanned film or digital images, supporting both color and grayscale data. Introduced in 1994 and updated to version 2.0, DPX facilitates the transfer of digital images for film recording and digital cinema projection, ensuring consistent image quality across different platforms and devices.

The PJPEG (Progressive JPEG) is a file extension for images that enhances the standard JPEG format by displaying images in successive waves of increasing detail, improving the user experience during slow network conditions. The JPEG stands for "Joint Photographic Experts Group", the organization that developed the standard in 1992. PJPEG is particularly useful for web applications, as it allows images to appear more quickly and progressively refine in quality, rather than loading from top to bottom like baseline JPEGs.
