Mux Upload SDK for Swift v1.2.0 now recognizes qualifying HEVC video as Standard Input, avoiding unnecessary conversion to H.264 and helping reduce processing time after upload. The release also adds a 1440p maximum-resolution option and configurable HDR handling, preserving eligible HDR by default or allowing apps to opt into SDR tone mapping.
