Read moreBy 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 […]
Read moreBy 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 […]
Read moreBy Pradeep Ramachandran Version 2.3 Release date – 15th February, 2017. Encoder enhancements New SSIM-based RD-cost computation for improved visual quality, and efficiency; use –ssim-rd to exercise. Multi-pass encoding can now share analysis information from prior passes (in addition to rate-control information) to improve performance and quality of subsequent passes; to your multi-pass command-lines that use […]
Read moreBy Pradeep Ramachandran Release date – 26th December, 2016. Encoder enhancements Enhancements to TU selection algorithm with early-outs for improved speed; use –limit-tu to exercise. New motion search method SEA (Successive Elimination Algorithm) supported now as :option: –me 4 Bit-stream optimizations to improve fields in PPS and SPS for bit-rate savings through –opt-qp-pps, –opt-ref-list-length-pps, and […]
