[Nick_Espo] “This is broadcast spec for uk not dvd.”
If it’s going to be broadcast my guess is they’re just trying to compress whatever this is enough to fit on optical media for you to deliver to them. MPEG-2 is a fairly good encoding method to maintain image quality while lowering data rate, however I’m surprised that they wouldn’t prefer you to output an uncompressed rendering to tape.

[zygotesoup] “i tried that toggle keyframe thing, but im still having issues when i want to start another camera movement it still shifts before it does what i want it to do.”
Believe it or not your problem has nothing to do with easy ease keyframes. Easy ease keyframes affect temporal interpolation, but what you’re experiencing is AE’s default auto-bezier spatial interpolation (you can change the default in Preferences > General > Default Spatial Interpolation to Linear, I recommend this). To fix your keyframes, select them and right click, then go to Keyframe Interpolation and change the spatial interpolation to linear. Note that if you want your camera to move smoothly around curves you’ll have to now go in and create the bezier curves yourself across the motion path (use a 4 view setup and the pen tool to change spatial interpolation visually). Linear spatial interpolation causes all of the motion paths to become straight lines.
[zygotesoup] “When it plays the “animation” i can see a cursor moving through each letter of the word but the word just instantly appears without fading in”
Make sure you remove any previous animation presets from the layer before you try to add a new one. If you have multiple text animators they can end up competing for your text layer. Start from scratch: delete all text animators on the layer and then try adding the preset.

I’m not much of a 3D guy, but most packages offer a way to extrude Illustrator or SVG paths, which is more often than not all you need to do for a logo.
I’ve used Cheetah 3D (www.cheetah3d.com) on my Mac for this purpose. It’s Mac only, pretty cheap, easy to use and allows you to do full renders in the demo version (but you can’t save the source file). It’s not as fully featured or advanced as the more commercial 3D packages (Softimage, Maya, C4D) but it is a lot cheaper, features a fairly robust tool set for the price (all the basics, skeletal animation, HDRI, rendering to movies/image sequences) and is pretty easy to get the hang of.

[KirAsh4] “It can’t be that easy…I’ve been testing and playing for over 2 weeks now and couldn’t figure it out.”
It really is that easy, the problem is if you make a wrong move somewhere along the line you’ll end up not having what you want.
Things to make sure of:
In the first comps (comp1/comp2) make sure you leave the wall at 320,240,0 (or whatever the origin is) and leave its rotation and orientation all at 0 so that it’s easier to animate the pictures flying on.
You must collapse transformations on comp1 and comp2 after you drag them into comp3.
Rotate and position comp1 and comp2 in comp3 in order to get the walls angled together right.
This one’s optional but I recommend it:
Right click your camera and select Transform > Auto-Orient and turn auto-orient off. This will allow you to animate your camera more like it’s a person’s head (instead of having to guess at the Point of Interest’s position you can rotate the camera 90 degrees on the Y-axis to look from the left wall to the right wall).

I think what I suggested the first time through was that you pre-compose your wall with the pictures you want flying onto it, make them all 3D layers, leave the wall at the origin facing the ‘camera’ (you don’t actually need a camera in this comp) and animate the pictures flying onto it. Then put this pre-comp into your final comp and enable Collapse Transformations on it (between the Shy toggle and Quality toggle, looks kind of like the sun), make the pre-comp a 3D layer, set it’s Y rotation to 45 degrees.
You would do the same thing for your other wall. The Collapse Transformations toggle will allow the 3D transformations you make in your pre-comp to carry over into the 3D space of your final comp. It should be easier to accurately animate the pictures flying onto the wall in the pre-comp as the wall will be a flat plane facing the ‘camera’ (with no rotation).
Then you can add your camera to the final comp and animate it.

[Nick_Espo] “MPEG2 50Mb/s I frame only.”
Was that supposed to be 5Mb/s? Fifty is outrageously high and would choke just about every DVD player on the market (above 8Mb/s and you’re risking this), of course I begin to wonder if this render is headed for DVD if your client is requesting 50Mb/s and I frames only (you might have enough compression then to fit 12 minutes of MPEG-2 on a full DVD-5).
I frames are keyframes in which the entire picture’s data is encoded, generally these appear every 15 frames in MPEG-2 encoding, the frames in between I frames are P or B frames and do not contain all of the picture’s data (only the differences between the previous frame and themselves) and so need much less data to be represented.
While it is possible to make every frame an I frame, it is unorthodox and doesn’t conform to DVD standards. You lose some of the major benefits of compressing in MPEG-2 with this technique.

[Nicholastoth] “Its noteworthy because if something does not support multi-cores, well, then the cores are useless.”
Of course when mentioning this, it is important to note that most high-end applications as well as operating systems are well aware of the trend toward multiple-cores/multiple-processors and are designing their applications to take advantage.
It’s interesting that you drew such a different conclusion than the article’s authors:
“Whether we’re talking about one, two, four or more cores, clock speed is a good way to increase CPU performance. But it doesn’t replace an efficient multi-core architecture.” [emphasis added]

[rob christian] “Sound in clip is 48khz 16 bit stereo. Integrated with video.”
Is it uncompressed PCM audio? Or is it using some weird funky codec?
I’m not much of an audio guy but I know that you’ll be much happier using PCM audio (AIFF/WAV)!
-
The only advice I can give (as someone who has never tried one of these) would be pre-comp, pre-comp, continously rasterize, pre-comp, motion blur =)
The samples you gave piqued my interest, and I think I might try my hand at one of these in the near future (;

[Ben Piercey] ”
On a 64 bit OS the skies the limit if you are using Nucleo/NucleoPro or AE CS3. Both force AE to run multiple instances with each instance able to access its maximum memory(which I think is 3GB on both 64Win and OSX).”Is this true even though CS3 isn’t a 64bit application? I’ve read some very deep articles on the whole 32bit v. 64bit issue and although my understanding is far from complete I thought that a 32bit app couldn’t address more than 4GB of RAM even if running in a 64bit OS. Although said 32bit application could benefit from an efficient 64bit OS implimentation (OS 10.5?)
Any info would be helpful =)
