Store twice as much and fast your videos on local disks or the cloud, with x265 HEVC
x265 HEVC Encoder is a free and efficient program for advanced users who are able to work without using a graphical interface, taking advantage of command line arguments.
The program lets you convert even Y4M and YUV videos to the HEVC (High Efficiency Video Coding) format, that achieves high quality (up to 8192 x 4320) while doubling compression.
Note that just by using the -h switch you can find detailed help on how to use this utility, the (simple) syntax, input and output formats, etc.
The main advantage of a x265 Encoder is that it lets you store twice as much and fast your videos on local disks or the cloud.
