These are my first successful shots matchmoved in Maya Live.

(http://matchmoving.tripod.com/matchmove.html) LINK (http://matchmoving.tripod.com/matchmove.html)

The footage was shot using my SONY DSC-T3 still cams movie function, and default settings for camera filmback etc... I will be getting my hand on a DV cam soon and I am still confused as to how to get the correct camera info Live needs.
The predifined filmbacks menu in maya doesn't have any options for DV, when I tried to do it in ICARUS I noticed it had different size CCD options.
So Im assuming I should put in on USER and input the film aperture and device aspect ratio manually. I think I understand device aspect ratio, which would be 4:3 or 16:9 for standard or widescreen (1.333 or 1.777 ?) .
But film aperture is a mystery to me, as I understand it in a traditional film camera it would be the size of the actuall film back. In dv would it be the ccd size ? I am also curious about the focal lenght constraint, which I can't use without the filmback info.
I will be using either a Sony HDR-FX1 or a Panasonic DVX-100


thanks, any help is appreciated.

Well you are going to hate me when I tell you this that the link in your post is still bad, coming up as:

http://%0ahttp//matchmoving.tripod.com/matchmove.html

But anyways...i was able to load the clips up:

Tree (http://matchmoving.tripod.com/treetest1.avi)

Phone (http://matchmoving.tripod.com/phonetest.avi)

Nice matches! They dont swim @ all. The perspective looks correct.

ok so my domain is offline and after trying a few different free hosts they all have tiny bandwith limits etc...
ill put it on my site when its back, otherwise if you want to see them msg me ill be glad to send.

The links worked for me.

The tracks looked good, though my playback is a little jerky (like the cameramovement... ;-)

Honestly I can't see why so many people seem to hate Maya Live. I had a few occasions where I got the best results in Live (and I tried all other trackers: boujou, matchmover, flame, 3d EQ). I think the ease of use of Live made it easier for me to get a good solution than in the other trackers. I just miss stuff like lensdistortion and so on.
Also one should definately try different values for the solver (number of root frames, filter value, etc). its worth it.

I dont know why people are like that either, I wish Alias would continue developing live.
For a long time i couldnt get it to track correctly until I started doin bidirectional tracking over my already tracked points. Before doing that I coulndnt get the accuracy to stay in the green. It seems you have to go in an manually do bi-directional tracks a million times, everywhere the accuracy turns from green to yellow.
I havent had a chance to use any other soft other than Live and Icarus. But now that i figured this stuff out, and vrljc explained the filmback stuff to me more clearly. I think I will stick with Live. I was thinking about making a tutorial, It would have helped me alot.
what do you guys think ?

Go ahead. Honestly, if you have to track manually, I think its really good.

This is a work in progress shot, where I'm trying to replace parts of a face. There was heavy motion blur on the markers which I painted all over her face, plus she opens her mouth so that the markers in the lower half where not usable for this time. Maya gave me the best results (motion blur was really an issue in the other trackers)
Remember its work in progress... ;-)

lookin good man, could you maybe post a workflow for face tracking ? just basic explanation of how you did it in live.
you have a wireframe shot of the face model ?

Nothing special. I tracked the camera and had my object fixed (This might not work for every case but was ok for me). I did however had to use much more root frames than the default and less smoothing.
All in all it was a little tricky, cause I did not have a correct model of the face (our 3D scanner broke and has not been repaired for budget reasons :shrug: ), so it was a bit tricky fine tuning the track cause I never knew was it my track or the model that was bad.
Lots of problem for the part where she moved the jaw... no chance to track something in the lower half then, which gave me some accury issues. However with tweaking the solver parameters I got a clean enough track. The little offsets which are still there, are due to my facial animation not 100% matching her movement. Needs some more refining. Plus lots of other stuff...

Here is a wireframe

Heyit looks so cool !!!
I've never used MAYA LIVE or any other tracker, but I really want to learn how to use it with MAYA LIVE (I need to use UNLIMITED that's why I have it and not complete)

Any Chance any of you guys will create a short VIDEO TUTORIAL (if it's big in seperate parts maybe ? Divx Will make the size decent and good quatlity)
I also using Combustion, is that all I need or any other software needed for the process ???
please keep show us those cool WIPs and Experiments it's really cool !!!

Sorry about my bad English....
