I've been trying to save my project as a video file but keep getting the same error message.

I've tried different settings and nothing works.

The file consists of 850 pictures with neither audio nor video clips.

I tried making a movie out of the pictures indicated with the yellow triangle sign and it works just fine.

I'm running the 2012 ver. on Windows 8.1

DirectX ver 11 is installed.

I got 2.20 GHz (8CPUs) processor on my laptop & 16 GB RAM.

Any help will be highly appreciated.
