    are you just telling us this for fun?

    Or do you want some help trying the find out why its running slow.

    Tell us more ( or some!) details of what you are doing.

    There are many reasons (too many to list) why Motion will run slow since it is not and never has been about *playing* video. It is about creating effects and titles FOR video. I've created projects where Motion will only get < 1 frame per second on playback (that usually means I have to *simplify* the project considerably...) The only way you can guarantee a smooth up-to-speed playback is to Export your project to video and play the video in a player like Quicktime Player. However, IF you have the RAM for it, Motion 4 will render as much of the timeline it can fit in the available RAM it has to playback with RAM Preview (command - R), usually, at full speed for as much as it can render. Motion 5 does not do as good a job at that.


    Lights are notorious for slowing Motion down, especially if you have shadows turned on (Spot and Point lights.) If you have reflections turned on; if you have emitters with high birth rates; if you have a lot of layers in 3D space; if Motion Blur is enabled; and the list goes on and on...  You can temporarily turn off Lighting, Reflections, Shadows, and Depth of Field from the Render menu, which should help speed things up a little bit. You can turn off extra layers (isolate the view to a few specific objects at a time) to speed things up a little bit. But mostly, you're just going to have to get used to Motion slowing down as you progress through a project.
