Very nice post. Always good to learn some new techniques. I like the music too. What was it?

Which background color do you think gives you the cleanest knockouts of Poser motion movies in After Effects (or Final Cut Pro)? I've noticed the standard grey background causes trouble when there are edge shadows on the figure, but a blue or green background can leave a notable border that is a pain to deal with. I suppose the answer varies with the figure and the scene they're being dropped into via compositing. SS

Skeetshooter, I'd think your answer might depend on what app you are using to do your compositing. If you have a chromakey function in your compositor, blue or green is probably the best choice because the software should handle the removal of those colors automatically. If you are seeing a border, than either the software isn't quite up to the task or something else is out of whack.

BTW, for compositing, uncompressed video is the best way to go, if it won't break your hard drive. Video compression can introduce artifacts that are difficult or impossible for the chromakeying software to remove. (A lot of chromakeyers originally had problems with DV video for just this reason. I think this has improved since, though.)

In the last compositing example you showed how you exported bvh data from Daz Studio, can you also do this from Poser?

I very much want to export camera moves along with character motion.  If you could please describe this or point to a how-to, I would truly appreciate it.

Very nice work btw.

Poser can import from and export to BVH format.

But you're not going to get camera motion in a BVH file.  BVH is intended for figure motion only.

Argh!  The link is no longer working.  I'll try again later incase this is temporary, but the site says that I've "recieved the wrong link" and that I should "contact the owner".

Very excited to take a look, I hope this is temporary.

Sorry folks it looks like ive already exceeded my  bandwidthf or this month on my"free" account at mediamax.com

anyway to answer skeet shooter:
You do not need to have ANY  "Blue screen" or Green Screen"
backdrops for chroma key knockouts.

you render your animated element/figure uncompressed at millions+
against the default black background in DAZ studio or poser ,C4D et al
and that "black background will come into you your post compositing program
as completley transparent revealing the new backdrop, Still or animated,
that you have layered behind it.

Thanks, wolf. Haven't been able to get that to happen out of Poser in any other way, so I'll give it a shot.

One other alternative... Set your Poser background to have a color similar to the color you're compositing it over. If you're compositing it over a dark background, black will do just fine but if you're compositing it over a light background you might try to come close to it within Poser. Since you're rendering with an alpha you're probably OK regardless of what you do, but this is an extra 'just in case' thing you can do to increase your odds of everything looking right.

Before they made me they broke the mold!

Anti-aliasing is what happens with Poser. Even with the alpha channel, you still get some "colour blend" which is why the poster before me is referring to.
