Resampling / Motion blur plugin for sony vegas or after effects

Does anyone know of a plug-in / way to add some small motion blur to a video without it taking forever to render

I've currently tried sony vegas's default smart resampling which doesn't add much but helps and takes about 5 minutes to render a 1 minute video.

I've tried real smart motion blur which makes everything look great but then takes 1 hour to render a 1 minute video.

Pretty much same thing with After Effects CC Force motion blur.


Is their something in the settings that I can change to make it not take so long? I've also tried rendering the same video at different frame rates all out to 30fps and the render times is pretty much the same. 


Also this is all for gameplay videos because I really hate youtube's 30 fps cap and don't get how 60fps isn't a standard.
