Video Won't Export

[natalievangelder]

I'm having a problem with storyboarder; I want to export my animation as a video, but when I click export nothing happens, and nothing shows up in the exports folder. I can export individual frames as images, so the route for the file doesn't seem to be the issue.

Same here, except I'm having this error displaying after it tries to export.

EDIT : I installed FFPMEG, now I don't have the error message anymore, but no export happening either.
Gif export works.
