Anders,

Mp works on most output formats through QuickTime. I've = only seen it not work on PNG codec QuickTime renders with or without alpha.= It never says MP is turned off, but the render will only go one frame at a= time. I assume because of the nature of how it writes a PNG encoded video.=

mm,

It's what i've found as well, that= for character animation it can often be better to turn MP off while previe= wing short areas. It would be fantastic if MP could start without the long = overhead, so it gives more benefit when working with short previews. I am i= nterested to know the answer to mm's question, can this be improved by = an update of the application? Until then, I often reduce the preview sample= resolution to half or third and turn MP off. I did not know that there was= supposed to be an overhead when starting MP, I just thought it was my syst= em or amount of RAM. This now tells me that my plan to build a new computer= with lot's of cores may actually not benefit much for RAM previews the= n, for character type animations.

Walter, if rendering to for example QuickTime rather than as an image s= equence, is MP being used then when rendering in the render queue, or does = it only use MP on image sequences?

Thanks

Thanks for your replies...

Ok, so it seems that for the= work I do, and the way I work, muliprocessing in AE is not the way to go (= I do a lot of character animation where i'm constantly previewing 5-10= second areas).=A0

Musings:
My rough understanding of MP in AE i= s that it's basically launching instances of itself, and so has to save= the file, launch these processes and then distribute the data to these cop= ies. Thus the long delay before rendering can start. Is this process just a= function of AE's legacy as a program that was created waaay before mul= tiprocessing in desktops or is this just the nature of the beast? It seems = like this isn't the case with other multiprocessor enabled apps I'v= e used (3ds Max, Maya)? Is there any way to improve/change this short of a = core rewrite of the application (which I don't see happening!)?

You're not seeing= an anomaly. There's noticeable overhead to start the background proces= ses, and while that may make sense for a long final render, it doesn't = always pay for shorter previews.

After Effects CC has a new preference that allows you t= o keep multiprocessing on for the render queue, but turn it off for RAM pre= view.=A0
