Basics and General Workflow

Preparation

downloading a source, looking at the video, some decisions (resolution(s) for the release, audio codec, group-specific requirements)

Writing the Script

imports, source filter (mention lsmash, ffms2), examples for resizing, debanding, AA. with images if possible

Encoding the Result

$ vspipe.exe script.vpy -y - | x264.exe --demuxer y4m --some example --parameters here --output video.264 -

Editors for VapourSynth usually have inbuilt support for encoding scripts you wrote. Use %encode --y4m <clip_variable> in Yuuno or the GUI provided by VSEdit.

Transcoding Audio

examples for qaac, flac

Muxing

mkvtoolnix
