From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

thanks, I'll try out the libx264 encoder next time
A couple other things, you generally want to do pixel format conversion before the codec, is specified. You should be able to get satisfactory results with
ffmpeg -i input.mpv -pix_fmt yuv420p -c:v libx264 -preset medium -crf 24 -c:a aac output.mp4Play with preset a bit since that is where your Quality/Compression : Speed ratio comes in, CRF is the quality it handles. So you set CRF for a ballpark quality you want, then change the preset, slower = higher compression, faster = lower compression.you can find more info here https://trac.ffmpeg.org/wiki/Encode/H.264#a2.Chooseapresetandtune but generally you don't need to muck about with profiles or tunes or anything else
You're probably aware already, but others reading this might be interested that you can access the same format conversion with Handbrake and WinFF if you prefer GUI tools. Remember your settings once and save them as a preset.
