render_video output directory does not exist

[henrieger]

Hi, I was trying to render a video using the render_video function, but it output the error:

 FileNotFoundError: Output directory does not exist: /home/user/teste-mosaico/My-Breaking-News-Video.mp4

It looks like the render_video function is trying to write to a directory instead of a file, and changing the second param of the function to "." fixed it, generating a video with the same filename as the title.

Could you fix it so it actually writes to a file?

The issue was that the documentation said the output was a file when it is actually a folder. Maybe we should allow user to write both to a directory (file name is the project name) or directly to a file
