x265 version 2.5 Released

By Pradeep Ramachandran   Encoder enhancements Improved grain handling with –tune grain option by throttling VBV operations to limit QP jumps. Frame threads are now decided based on number of threads specified in the –pools, as opposed to the number of hardware threads available. The mapping was also adjusted to improve quality of the encodes with minimal impact […]

x265 Version 2.4 Released

By Pradeep Ramachandran Encoder enhancements HDR10+ supported. Dynamic metadata may be either supplied as a bitstream via the userSEI field of x265_picture, or as a json jile that can be parsed by x265 and inserted into the bitstream; use –dhdr10-info to specify json file name, and –dhdr10-opt to enable optimization of inserting tone-map information only […]
