Rendering interval by frames I am new here and i hope i am not making anything wrong.
So, my problem is : I want to render my animation, i have 5+ computers to do that and the scene has 2730 frames.
Its possible for example : on computer 1, render from frame 1 to 500; on computer 2 from frame 500 to 1000;on computer 3 from frame 1000 to 1500 and so on ? 
If yes, how can i attach each rendered animation to the other ?
Another option that is available if the machine are on the same network, is to enable placeholders and disable overwrite in the render output settings, then have each machine render to the same network folder. Each machine can then render the same frame range but each will render different frames.

While getting a little more complex, there is also a network render addon included with blender.
