Does anyone know a good site where I can learn about video terminology? I mean things like bitrate, codecs, containers etc. I have become fed up with GUI front-ends for ffmpeg (which most video converters are seemingly), which I have found either slow and freeze-prone (SUPER), not easily allowing me to do what I want (Quick Media Converter), specific to one format (HandBrake) or simply not working at all (MediaCoder), and I want to start using ffmpeg manually myself (or write some .BAT scripts for conversions I do regularly), but its hard to understand what options I should use etc., so I would like to read about what the various terms really mean. The ffmpeg documentation doesn't really specify what each option does, just how to change it. Thanks in advance.
