i've been trying day long sort out, checking similar threads no success. stretch's cannot save matplotlib animation ffmpeg helped previous errors (i had ffmpeg path wrong), kept getting access denied after fixing it. my ffmpeg binary on c:\ffmpeg\bin a nice alternative able export gif files, keep getting ascii error imagemagick. think both problems related, wanted sort out ffmpeg first. i think problem might have fact i'm working canopy (in windows 8 64bit), pretty hegemonized path variable , broke things along way (e.g. can't open idle since installed canopy, didn't tried fix yet). fixed things along way found @ least 3 distinct path variables, of updated: windows advanced settings path (set manually), windows console path (set via console setx), , sys.path (set or checked @ runtime), adding ";c:\ffmpeg\bin" , ffmpeg is. regardless sort out problem or not, learn of these environment variables relevant what, find confusing. the code following...
