MarsSeed [1] filed a deletion request for avxsynth-plugin- masktools2-git [2]: It is useless to keep this broken, EOL plugin from more than a decade ago, as avxsynth itself is not compatible with current libraries, and is itself EOL since 9 years ago. Successor of the latter is avisynthplus, available from Arch repo. [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/avxsynth-plugin-masktools2-git/
