Yo folks! Anyone know of any scripts out there that would convert camera data generated with the Voodoo motion tracker to a Poser camera? Right now, I have a good matchmove setup that I can get seamlessly into Maya and I"ve tried exporting the camera from that via Poser fusion, but apparently Poser Fusion will only export single frame camera poses! Surprised I hadn't ran into that before. Seems like one serious deficiency to me, but then again they don't really push the animation capabilities of Poser as much as I think they should. A quick workaround would be a combination of mell script and python script to 1. use the Poser cam export to output the camera at each frame to a directory then 2. step frame by frame through the Poser scene applying each camera pose from said directory to each frame.  Just spitballing some ideas here, but I do think that it would be damn nice to come up with a semi-reliable way to get real world camera movement into Poser. -Les

Do you has a sample file , or set of files  to take into poser. ? The script should not be that hard to do.

Attached (hopefully) is .ma (Maya Ascii) file that you can open in a text editor to see the results of the matchmove in Voodoo. -Les

edited: Ok. Uploading didn't work. Ah, duh. So, attached is a link.

the script will terminate with a message to manually set the endframe higher than the frames in the import file, dont know how to automate that.
the translate values will need to be scaled from whatever units to Poser units , thats pretty easy. 
it needs a dialog for selecting the input file - not hard but havent done it :)
uses Main Camera as the camera to animate
does not use the zoom info yet - thats also not hard to add.

Theres a lot in the file I dont understand , I have just grabbed the camera animation curve.

Yeah, a Maya file has a LOT inside it that's hard to grasp if you haven't been dealing in MEL for years. My MEL skills are still not what I'd like them to be and Python... nope. Nada. Not there at all.

The function curves are really the most important thing since I think one can manually set up the all the film back stuff inside Poser to match the footage. Can't wait to give this a shot. -Les

Hmm... I keep getting an error at line 8 saying no such file or directory, even if I alter the path in the script to point to where I know I have the .ma file. Any ideas there? -Les

that line ?  use either / or for seperators. and watch the quotes.  I copy paste from explorer for the path. 

Here is that script with a file selection dialog.

Just finished setting up a shot using your script. It's working pretty well. I think a few more tries will help get some little kinks worked out for usage sake.  There's a really good description of Poser vs. Maya scaling here: http://www.digitalartform.com/archives/2009/04/matching_poser.html

Don't know if you'd want to plug something into the script to adjust for the difference in scales between the two, but I did notice that the scaling seemed to be integral for really tweaking out the results. I should have a test clip comped together sometime tomorrow; when I do I'll post it. I am really excited by the possibilities of this because with the right render and material settings, and post production,  Poser is really capable of rendering some very useable footage for stuff like this. -Les

the input file seems to contain the units used. - at least thats how I read it . I extract the value of the translation in the script so it just needs the conversion factor added. If you always work in the same unit that would be easier. The issue is getting an accurate conversion which might take some trial and error.

Gotcha. I'll come back here with more feedback, but at least this is a good start. -Les

I added the focal length parameter. 
I added the conversion factor , taking the unit from the file
----    the only unit i test for is millimeters , which is in the file i have test.ma
----   adding other units is easy

Cleaned up the print statements.

I realized I dont actually set a keyframe , I may need to add that explicitly

Dude, I'm amazed.  This is not only some top notch work, but could be incredibly handy for all kinds of Poser-to-film based projects. I don't know if you realize it, but for some of us in the indy film community, what you're making here is something we've all wanted for YEARS on end. Seriously. Thanks. -Les

Unless theres a problem with it , thats the final version.

sweeet! Dude, you rule. :) -Les
