Hello.
I'm sitting here s.einem MacPro 2.66 GHz quad-core, 8GB RAM and 750GB HDD.
If I am a movie from After Effects (with a lot of color correction and some jokes) rausrechne and in the "activity monitor" look, it is actually utilized only about 30% of the CPU and just 2GB of RAM.
Can it be that I have no RAID but only a single HDD? S.was or may otherwise be?
thanks for your help
Antwort von RickyMartini:
The hard disks have nothing to do. After Effects can use it as a 32bit application only up to 2GB of RAM. The too low CPU utilization could s.nicht optimized multicore are adapting.

s.nicht could be optimized multicore adjustment. what is with this system, the optimal adjustment?

Mylenium Thanks for the tip - was often just prior to weld a hanger;)
activate and the with the multicore I had been synonymous.
what exactly do you set with "so as to be used 2 additional cores"
8GB of RAM is really enough?
interesting is that: if I make the slashcam render test, then my cpuauslastung goes to about 91% of synonymous 8GB RAM go down to around 2GB!
But if I put my new project with many rendere unterkomposititonen and effects, then the yield is very low.

This then slows down from your system ...
Antwort von Mylenium:
You have a point there "CPUs to Leave for other applications. Accordingly, you ask to come out to 1 or 2, so that your main process AE and a further 1 or 2 other background processes. You do not synonymous should see it absolutely. Depending on the project, it can of course be, that you can use all the cores. Generally speaking, there's no universal formula. It all depends on what's going on in the compositions is, of course, synonymous and other system factors.
Did you just generated elements in AE, it can be very fast, because no image data must be read. Do you have a lot of footage, it can be miserable with MP slow because the speed of your hard disks can operate, not all processes. Depending on the flat. The same goes for the memory usage: simple things like text only barely need storage, large pixel images for the more. And of course things like precompositions or time-based effects that must always take into account several frames can bring the whole completely out of step. In case of doubt here is not s.wirken MP, because it anyway ausknipst AE.
Synonymous, it depends, as you render - Movies Now ever need to be processed sequentially, ie if frame A is not ready yet, Frame B can not be saved. The same applies's reading of the data. In other words: ideally, you work with image sequences, where it does not depend on it, what the picture is calculated, as long as all s.end eventually finished.
To mathematics: have Mac Pro 32bit process auf'm kannste 3GB. The foreground process can certainly fill them synonymous, because of overhead for user interface and so. If the present time synonymous for background instances, you beio'd 4x3GB = 12 GB and 8GB with underserved So, the more so, indeed, under certain conditions, the OSX synonymous almost 1 GB (Spotlight, Time Machine, etc. all need active) and you may synonymous nor other Programs have open, at least free to surf on the web, while the box will render. Thus, at least in theory. As the real load is then, does one really only at the (trial) rendering.
From the above reason, I believe benchmark synonymous of very little, just such a simple knitted like Slashcam. This one would have to analyze more deeply and offer more scenarios.

Thanks for the really good explanation!
Do you have a lot of footage, it can be miserable with MP slow because the speed of your hard disks can operate, not all processes. True, it is much footage - I have a lot of material in the 422nd Apple ProRes codec would not it be faster to read of a RAID (0) to the data?
I eigentl. eh already have a system disk and read another internal disk of the project (because I thought that if I had everything on a plate (system and project) that he then read and write on a disk must.
