When the Source Filmmaker exports your movie, its default is to render at 720p. This means that your movie will be 1280 pixels wide by 720 pixels high, which is an average resolution for most movies made with the SFM. If you want your movie to have a higher resolution, you can instead render at 1080p, which means a movie that is 1920 pixels wide by 1080 pixels high.
The snapshot button is the fastest way to export still images from Earth Studio. When you take a snapshot, your current view is immediately rendered and downloaded as a .jpg file at the resolution specified in the project settings.
The reason why the motion picture industry uses 24fps is that it is a industry standard, and what if you now need to render an IMAX sequence with 60fps, in this case your 24fps motionblur will create unrealistically blurred images. You should always use the fps which is required by your output medium. If you mix it with real footage, you should know which shutter speed was used to setup your motionblur correctly.
If you want the best quality then render everthing as needed for your output medium, size and fps.Next if you run out of rendertime and there is no way to complete the job in time, start to reduce quality. You could try to do motinoblur in post with a vector blur pass. Maybe reduce GI bounces. If nothing works, then I would start to reduce image resolution. 2b1af7f3a8
