Convert G4 to DPX

The G4 file extension, standing for CCITT Group 4 Fax Image, is a specialized format used primarily for storing black-and-white facsimile (fax) images. Its origins trace back to the Consultative Committee for International Telegraphy and Telephony (CCITT), now known as the ITU-T, which developed the Group 4 standard in the 1980s to improve fax transmission efficiency over digital networks. This format employs a high compression ratio to reduce file size while maintaining image quality, making it ideal for archiving documents and transmitting faxes in professional and business environments.

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.
