Rendering with Camera Visible

Maybe I'm missing something but other than using a screen recorder, is there a way to render out a scene that also shows the "audience" camera.  This would be extremely helpful for breakdowns and tutorials...
Currently using HyperCam2 and while I can get both the scene and camera playing together I can't get it to match the same speed as the video rendered out from HitFilm (If I do manage to get the speed right, it's a bit too choppy).  Furthermore, screen capture doesn't work for scenes that have tons of VFX, models, particles etc going on for more than the "pre-render" memory will allow for as it can't play back in real time.
