What are Blenders strengths and weaknesses at compositing?

Hi-
I’m finding information on Blender’s compositing features scarce, so i’m asking for feedback on it.
I’m looking to do posters incorporating bitmaps [& vector art?] positioned at various depths, and of course 3D objects. As 2D fits into 3D but not vice versa, i’m thinking of Blender [or other 3D app??] as my core authoring software.
Since print output is my final goal, resolution is a big concern.
Is Blender up to it? Or should i go After Effects or??? [I’d hate to do so, because i don’t want to learn or pay for all their (unneeded)motion features.]
All informed opinions enthusiastically welcomed…

Have you seen the new features in Bf-Blender? Compositing will become SO much easier!

Blender 2.42 will be a full blown node based compositor, it is being used for project Orange now, so it is already usable. However, the actual release that will contain it won’t be for about two months.

In the meantime, you might want to create your 3D stuff seperately, render with the alpha channel on and composit in Gimp (or Photoshop if you’re lucky enough)!

With sequence editor can be composited 3d objects and 2d graphics
to it by making planes from camera view and setting those to different
depths/distances from camera and for those win as mapping coordinates
so those fill the area of render, of course those bitmaps with render image size and black and white alpha images.

How did they render GI or Caustic effect with the new node compositor if yafray don’t seem to work with the new function.Did they manually do it?

When i first looked into Blender i wasn’t sure it could do what i needed. Now i am sure. Full node compositing!? Fluid dynamics!!!? Wow!
At this rate it’ll overtake AutoGreed in a year or two.
Yet now i’m sure i WON’T use it, for now anyway. Why?
The docs are either there, but scattered and minimal, or non-existent. And i just don’t have the tec chops needed to figure out how use the features myself.
I think part of the problem is that open source progresses in spurts: 2.2, 2.33, 2.37, 2.4, and so on.
That makes for a moving target that discourages doc writers [volunteers and commercial]. So the docs gap seems to be built into the structure of Blender’s evolution.
Anyway…
I’ll have to hope for the docs situation to improve before i can commit to Blender. Thanks anyway people- i appreciate the attempts to help, and i really hope the Blender community comes to terms with this crucial bottleneck. An un[der]documented feature is a non-existent feature! [to us noobs anyway]

You can waint as long as you want.
Perfect documentation won’t exist unless you hire a company to do that.
If you’re willing to go for the OSS solution you accept the fact that you’ll have to search harder for the answers.
Most of them are out there, all you need to do is search and search.
If you want an application that gives you everything on a plate, including a 300 page tutorial, you’re at the wrong adress.
Go Max and Adobe.
