Billy Wilder's 1950 classic, *Sunset Boulevard*, delivers one of the sharpest satires of Hollywood's myth-making machine. When the film's restored version entered a global re-release program, LI TRUST handled the cross-border transfer of the restored 4K master. Restored classic films come with unique transfer requirements: the files from original film scans are typically in a specialized RAW format, with a file structure that differs from standard modern digital production formats. This demands a transfer system with full compatibility across a wide range of file types. LI TRUST's transfer system supports OpenEXR, TIFF sequences, DNG, and other professional formats, ensuring no format conversion or metadata loss occurs during the transfer. The master files for the restored *Sunset Boulevard* arrived complete and on time at the Chinese distributor, providing the technical foundation for this Hollywood classic's re-release in the Chinese market.
