The post you noted is VERY simple process… if my memory is correct… there was a question as to how they did this on the motiongraphics site… and, the answer was basically this,…
The player only had on 3 layers of shirts on at any one time… each were specially taylored so that they would not be visible as an under layer.
The only “trick” was that at about the mid point you will notice a person walking in front of the camera carrying basketballs in a net bag tossed over his shoulder. This was used so that the shot could be divided up into two parts… the first part had about 3 (or so) shirt layers… then, the person crossed in front of the shot to provide a cut point in the editing process… and, then the player had a new under layer of shirts to complete the shirt removal shots.
So… basically, there was no specical effects used… just carefully planned and shot scenes.
Simplicity is sometimes the best tool for the job… and, all to often I see some posts (not yours, of course) assume something is done using AE when it was just good camera work, great planning and knowing how to use a typical NLE software (not a compositing software like AE).

There are a few tutorials on slowmotion… you just need to scan/search the tutorial page (side note: they use timewarp).
However, the slowmotion you noted on the sites could have been done the best way to do slowmotion… and, that is shoot at 60 or 120 (in the NTSC world) then use any professional level editing software to create the slowmotion by reducing the fps to 30 for the 60 or 120 fps original shot.
In short, the best slowmotion is done shooting at a higher frame rate then reduce the frames in an editing software. I find it much easier to an editing software rather than AE to create slowmotion.

I’ve done it before and this is what I did…
I used Mocha by Imagineer to rotoscope the clip and then simply layered the roto-layer over the existing background and faded the top layer (i.e., roto-scoped layer) as those portions of the body passed throught the wall. I never used AE… I used Avid/Pinnacle Liquid and Mocha. …wait a minute… once, I did used an AE bulge filter to make the text I had characters walk through seem to bulge a little as they moved throught the text.
Well… there is my tutorial. Pretty simple – BUT VERY TIME CONSUMING. If you want a video tutorial… well, that would be extremely boring since it would be all about spending a kazillian hours rotoscoping each frame… (or in my case, you would just look at the rotoscoping tutorials on the Imagineer’s site).
Other methods? … yep, but they would use a green/blue screen keyed charater instead of rotoscoping….much easier but requires more knowledge about how to shoot on a blue/green screen.
There are a few existing tutorials about screen keying and roto-scoping with AE (look in the tutorial section of this site noted at the top)… but, there are some better tips/suggestions with regard to screen-keying that can be found with a google search.
Bottom line… do a search with key words… roto-scoping, screen keying, etc. Finally, this walk through wall effect you want is more of a set-up of the scene issue and camera setup issue and less of an AE composition issue. Which means you might do a search of some forums that concentrate more on camera work and video direction/production.
As you may notice, this effect is not done very often for a reason… It is very time con$uming IF you want it to look good/realistic.

The simple answer to achieving this not so simple effect is this:
How much effort you take to acheive this effect depends upon how you set up the walking character and the wall plus exactly how accurate/realistic of an effect you want.
Personally, I have only been able to achieve this effect that actually looks good by rotoscoping the character and using each roto-framed matte to fade through the wall (…which means you do not want to have legs included in the scene)…using a green screen can also achieve a similar results IF the green screen is done correctly and planning of the shot is done correctly.
No matter the method, to achieve this effect accurately… you will need LOT of time to commit to the project (i.e., lot of trial and error… depending on experience). Other methods will work that are simplier, but you may not get the kind of accuracy/realism you may prefer.

Does AFX have a footage stabilizer? How well does it work? Would shooting HDV allow me to create a better stabilized SD shot?
Not sure I can answer all your questions… but, I’ll give it a shot… AE does not directly allow for video stabilization…however, you can do some stability adjustments using tracking information (…exactly how you would do this would take a tutorial length post… I believe Kramer has a tutorial that uses this method but it does not reference/title it as a stability tutorial directly). The easiest, best and least expensive stabilizing software I have found is Mercalli by Heroglyph (…if memory is correct, it is a plug-in for AE).
Shooting with HD will not create a better stabilized SD shot…only a stable platform and technique will do that…however, HD does give you better options as to how you might be able to enlarge the view in editing to help minimize movement of the shot. Personally, I would spend more time trying to figure out how to pan and zoom smoothly than try and do any software stabilization in post. Good camera work will make for much better video and video editing than any stabilization software could provide.
As for using HD for animation… I don’t understand the question… animation is not video generated.

BTW, based on your post… it appears you are going to try an use AE as if it is an editing software… well, it can be used that way… but, it is much more difficult to do your editing than if you used an typical NLE software.

Have you tried to send and e-mail to trapcode?

I don’t know of an EASY solution to your problem…
The easiest solution… is to add a tight matte layer of the original video behind the shirt to fill in the wholes created by the keyed layer.
Other than that simple solution, the only other work around that comes to mind and will work for certain is to roto-scope the video… and, if you have a lot of video… that will take a HUGE amount of time unless you try and use MOCHA software… even then, there is no guarantee it will work or look well.
Hopefuly, others may have better suggestions…

do a search with “cartoon” or “cartoon effect” as keywords.
You will find lots of good threads on this subject.
The example you posted actually looks as if it is a “cartoon” outline only of a video… with water color like matte layers behind the outlined video.
There are some other subtle effects such as reducing the fps to achieve the onion-skin cartoon creation method in the video as well.

There are a lot of tutorials on both of these subjects – green screen and tracking…
These are two highly effective way of creating unusual effects… IF they are done correctly… If done incorrectly it can look cheesy.
A few hints…
Green screen… Lighting is crucial. Shadows are problematic.
Tracking… Patients is crucial. …Time consuming.
For tracking and rotoscoping, I use Mocha by Imagineer… it is light years ahead of many other tracking or rotoscoping software… but, it is very expensive.Joe Moya
