Installer is 14 megabytes. I am serious, for x64 version. For 32 bit it is 12.5mb.

And it has spectrum editor (very simple). Works perfect with MKV and MP4 videos (you can have docked or overlay video visible). Sadly, can't mux audio back (or I didn't find how) and you need to use avidemux for it. Has all necessary stuff, and normally works with most useful plugins that I tried. But sometimes it can hang with some VST3 plugins especially, so make sure to check first.
Huge contrast with modern bloated mess.
