'''Step 2''': If you get "Command not found", add the /bin folder inside ffmpeg directory to your PATH.

'''Step 3''': Set the current directory of your command prompt to the /images folder.Execute the command 
<pre> >ffmpeg -framerate 30 -i "1%08d.png" -r 30 outPut.mp4
                    ^                    ^
                Framerate matched with simulator </pre>
The number after -r denotes the framerate of the video, its set to 30 in the above example.
