Here is the problem, I am compositing a rendered passed 3d. I composed the materials in ae cs3 using it's actual pixel ratios and format. I add it to the render queue, as a quicktime .mov (since I a using final cut), as animation and straight alpha render. Now here is the problem, When put it in FCP, the materials looks pixeled, the edges are jaggy most of the details are lost, and it seems low res in an Sony HDMI Monitor. I have changed the sequence codec to an rgb out. I am still getting that problem.

The screen resolution and pixel aspect ratio of your rendered footage may not match your FCP sequence.
If that's so, create an AE comp that matches what you're using in FCP. One of the comp presets will probably do the trick. Then nest the comp with your 3D footage in this new comp, and scale the nested comp layer to fit the new comp size.
You may also have rendered the wrong sort of alpha channel. Unless modified from the defualts, FCP generally likes Straight rather than Premultiplied alpha channels. If there's any doubt, you can simply render both a Straight and a Premultiplied version, then see which one works best.
thanks, add question, does pixel aspect ratios has any thing to do with the quality of the render?
Also I remember that may material's animation is one stationary movement. meaning the object rotate around it Y axis. The animate the z space axis in after effects. since the director want it to pass through the camera. Does any of this effects, causes the materials pixelate in render?(since I see in the playback, (via: ae) doesn't pixelate.

Not very much at all.
"The animate the z space axis in after effects. since the director want it to pass through the camera. Does any of this effects, causes the materials pixelate in render?"
Yes, it does!
You should do the z-space animation in your 3D application as well. Do NOT do it in AE, or you WILL get pixelation.
Thanks for the help once again. I just got one more follow-up question. What render codec, should I use, for an HD render??. Our machine uses blackmagic extreme, with a HD monitor for output??

[marcdaniel.villarin]"What render codec should I use for an HD render?"
Use the highest-quality codec you can. This could mean more rendering in your next application. If you want to avaoid that, use the best-quality codec you can that your next application can use without rendering.
