Read moreBy Tom Vaughan Clogged pipes Annual global Internet traffic is no longer measured in Megabytes, Gigabytes, Terabytes, or even Petabytes. This year, global IP traffic will be more than one Zettabyte (a trillion billion, or 1,000,000,000,000,000,000,000 bytes)[1]. By far the biggest driver of IP traffic growth is video. Today, more than 70% of all IP […]

Read moreBy Tom Vaughan x265 has ten performance presets which enable anyone to make a good choice between encoding speed and compression efficiency. These presets are combinations of x265 settings that should provide the best possible result at the encoding speed that you want to achieve. If you want the highest compression efficiency (quality at your […]
