The speed of the render depends on your project, the effects applied, the source footage, the output format and the rendering engine you used. Since we know nothing about your project or your system or your version of AE it's impossible to tell if the render time is normal. If you want to save a ram preview then there is option for that under the composition menu providing you have set up the output module properly.
ok.. Tks so much Rick.
I have another question..
i have a template with a group of itens. If i copy that composition, and change an example a text of this new composition, they change the original. How i can change the copy without changing the original?
if you want to modify a template file you have two choices. The first is easy because you cannot save a template file without getting a warning, when you say you get a project file (AEP). The second option is to do a save as I can save a new template file under a new name or just a new AEP. When you have the new files then you can make your changes. A lot of templates have text buried in pre-comps so that can give you trouble and less you duplicate the pre-comp inside the project panel.
ok, but in my case, is like this...
at 0:37 s , this first composition. I wanna do more 6 copies, but let the effects of the original. But i want to modify every copy.
How i can do?
Most templates make heavy use of precomps. Heck, so do most of my projects that I create from scratch! Precomps are a very powerful tool in AE. You often need to duplicate the precomp in the project panel and mess with things inside of it. The problem comes when comps are in comps that are in comps that are in comps... In that case there will be a lot of duplicating and replacing of items.
You might look into use the TrueComp Duplicator which is a third party solution.
Hey man, txs so much... But exist any kind of plug in that makes it fast or another option, that i can do a render ?
Before we could say anything about "fast", we would need to know what you mean when you say "slow". Do you mean, "not instantaneous"? "Not real time"? "Several Minutes"? "Hours"? "Days"?
And THEN we would have to know what is going on in your AE project -- the effects being used, the number of lights in 3D, whether you're trying to use ray-tracing.... all of these things and more affect render times.
It's not the easiest question to answer without the proper information.
Who marked the answer as "correct"?
Try using AE 2014, you might see more cores of your machine actually rendering.
