So just purely for understanding what goes on behind the scenes and my need to know how things work, I found a blog post on x265.org that talked about a new Version 3.0 of the encoder that they have rolled out. Naturally I got curious so I'm asking here if anyone knows what version Avidemux uses? Cheers!
If I am not mistaken, the latest 64bit MinGW, VC++ and macOS builds use 3.4, i.e. the latest. The last release, soon one year old, might be on 3.2, but unsure.
