Free Software that I rely on. One per day.
Day 18:
MKVToolNix
This is a tool kit of utilities, including a GUI front end, for manipulating Matroska streaming multimedia files (usually "MKV" or "MKA" files).
The Matroska container format allows for multiple audio, video, and text streams, which means you can encode a video with multiple options for audio and subtitles (as well as alternate video tracks).
It also supports setting up "Chapter" marks.
A must-have for authoring and checking complex videos for streaming and download use.
