In general, writing custom batch scripts to use with a handful of cli tools (Curl, PhantomJS, FFMpeg etc) will get a lot things done. No need to install a different tool for every different task.

Plus Adobe Photoshop and Premiere. But as mentioned, there are good replacements for that, like Gimp or Davinci Resolve (both free).
