The other day I came across Connie Kleinjans’ page of “two-minute versions”
of G&S shows. She’s got two versions of Gondoliers and one each of Iolanthe and Ruddigore.
The technique is the same as in blackout poetry:
take the whole work and black out all but the most important and/or funniest bits.

Authored by Arthur O'Dwyer, Quuxplusone offers  explorations of C++ programming language features, standard library design, and modern C++ development practices.

A walkthrough of creating a 'two-minute' supercut of the Gilbert & Sullivan opera Iolanthe using ffmpeg and yt-dlp. The post covers the technical challenges of clipping and concatenating 169 short video snippets, particularly the problem of audio/video timestamp drift. Three approaches are compared: clip-then-concat (causes drift), single filter_complex invocation (quadratic slowdown, memory issues), and a hybrid approach using filter_complex in batches of 20 clips followed by a final concat copy. The author shares the resulting Bash and Python scripts.
