When trying to render an animation, it doesn't work So I recently downloaded an intro that I found that I liked, and decided to render it to see if it worked. Well, evidently it doesn't. When I click "render animation" it says "Can not open or start AVI movie file". I will be linking a screenshot just so you can see. If there are any questions that anyone has to learn more please do ask. The first picture is before I render it, and the second picture is after I render it. I try to render it as animation, and the error message appears at the top near the middle.
It's likely to be one of two things: 


Either the output path you are trying to use is invalid or trying to write the file to a protected non-writable path on your machine, 
OR you are trying to use a video codec that your OS does not support.


Try switching up your output path and/or your video codec and see if the error goes away.

Bonus Tip: It's best to render your animation to a sequence of still images (PNG, JPG, etc), and then render the video from the images. Lots of reasons why this is better (some reasons include: in case animation render fails in the middle, it's easier to render video from images instead of raw render, etc).
