Hi Sunil, >From the very first glace of your command line, I think you have missed the --preset option. [https://x265.readthedocs.io/en/default/presets.html]. You can try the ultrafast or superfast preset for higher performance. Regarding the overview of different CLI options plz check the x265 documentation: https://x265.readthedocs.io/en/default/cli.html
