Hasta La Motion!

Hello,

A problem that I have when I track my footage in Syntheyes and place a 3d object over it in Syntheyes or 3dsmax (same problem) it doesn’t completely match the footage. For example if I place a Box over a building the perspective isn’t perfectly right. Like half an inch off. The track is solid and the cube does follow the camera perfect too.

Is this a lens distortion problem? Or is there something wrong with the settings in my 3d camera?

I hope that someone can help me out with this.

Thanks alot,
Maarten

Hi there.

Here is a movie (great) created by maya and realflow
http://www.vimeo.com/3911557

at the first scene, there are waves.

I tried to get a similar effect with realflow (realwave) but it seems that it either has VERY high subdivision (just look at how sharp it looks !) or it’s being donw with some other technique.

To be honest, I do not believe the subdivision lie.

How can this be made ?

I messaged the author and got "realflow and maya" reply.

I’m using c4d normally.

Hi @ all!

I have a strange alpha channel problem, maybe someone can help me.

Said first, this happens both with straight AND premultiplied rendered images. We compose in 32bit float, linear blending on. But this happens also in 8bit.

I attached a jpg to show the worklfow better.

a) I imported a rendered cube from max, exr file.

b) i extremely over-exposed in AE

c) i put the original cube on top

–> jaggy and strange edges…

solution for now:

ignore the alpha channels and at the end, a re-imported cube with alpha activated cuts out the alpha channel “on top”.

But this is not a real good solution, because if the comps get bigger and bigger with lots of reflection layers and so on, there is no simple “cut out on top” solution.

Do you have any infos how to handle this strange issue right?

Like I said, detailed pic as an attachment is inside here.

Thx a lot, Dez

The reason I ask is because I know AE in and out … it’s been my comp software of choice for many years, and was used in my Visual FX degree program while in school. I’m aware of node-based software, such as Nuke or Fusion, but the interface and workflow is just so drastically different, I feel I need to invest in some classes to learn it (something I don’t have time for at the moment). As a junior compositor, it’s probably in my best interest to eventually learn the node-based software, but is that something that’s high priority right now? If there are still Visual FX (not Mograph) companies out there that use AE, I would be interested in who they are and what they do… if not, then damn… I gotta find some time or really good tutorials to get on this stuff!
