FAILED TO OPEN FILE FOR OUTPUT: INVALID VIDEO SIZE

Post by eliscio »

When rendering out using the animation plugin, often people are getting this error. I asked some folks to change their display resolution back to 1920x1080 but it seems this is not a fix for all although it did work for some people.

I've never seen this error, but I personally don't use this plugin often. Is it occurring with a particular format/codec maybe?

Hi, were you able to find a fix for this? I am getting the exact same error message. Tried manually reducing the size of my window but nothing is working. Thanks

Preview is working ok, Export frames is working also, but when you click Render, that message apperas
we tried with MOV and other video formats, same message.

frames can be exported and processed in third party software, but it would be much easier if Render work
