Render OpenGL

I am not sure if this is the right place to ask this question or not. I am editing an animation in blender using the sequencer. I have linked every scene into an empty blend file and from there I am bringing the scenes into the sequencer. In the sequencer preview window I can see the OpenGL preview of the edit. Is there any way I can render a quick time movie of this without having to render the finished scene?

The “preview render” button on the bottom of the 3D window can generate a similar thing but it’s somewhat junky… intended for animatics.
