Wow, this looks awesome! I can afford SynthEyes and this :). I’m quite the happy matchmover.

Pftrack & Solving zoom’s

Hey guys,

Thought I’d post this on several sites, just to increase chances of getting a solution !

Solving for zooms in V5, is it different from previous versions?

After solving a part of a clip that is ‘constant’ trying to then solve the ‘variable’ parts and so on, seems to just bugger up the solution. Like it ignores what I’ve done and solved, and tries to update the whole shot, rather than just the newer parts.

I can step by step what I did in the past, but it doesn’t seem to work any more. :confused:

Cheers !

PF Track problem in solve

hi all, i am working on footage(1920X1080X 25fps) shot in HVX200P2 handhelded with lot of motion blur. when i try to solve first 100 frames without motion blur i am getting the point cloud in reverse shape of the building in shot.

this is how the building is

hope u all understand the problem.Looking for solution … Thanks in advance.

stereoscopic tracking in Pftrack

Guys can someone pl make a tutorial on pftrack stereoscopic tracking..
I cant understand stereoscopic tracking form the pftrack manual…

A nodal track with zoom.

I’m trying to do this long tripod shot off a bridge where I zoom in on various parts of the scenery where I want to put in some 3D objects in Maya.

What would be the best way to go about doing this? Can I do a camera solve in a tracking software and then just line up the scene geometry once in Maya?

Or would it be better to make one panoramic image and do all the camera movement in software?

How would you go about a shot like this?

2 track points as 1

hi, i am using pf track to find a good tracker and i wasn’t still able find any good track. i tried user feature track but got nothing. then i used auto track. now i have found 2 points. 1 with information of the first half of the video and 2nd with information of the next half of the video. is there anyway i could export these points to be used as 1 track in nuke?? if not then i really could use some alternative suggestions?? 🙂

Survey data in PFTrack to facilitate set fitting?

Hi,

I am wondering if someone could shed some light on the workflow of incorporating the Survey Data feature in PFTrack to facilitate the set fitting process later in 3D program.

I have an interior scene that is already calibrated in ImageModeler and with proxy geometries built and locators placed on specific positions in Maya.

I then 2d track user-features in the positions corresponding to the locators.

User-features are then added into Survey Data window. The SurveyX, SurveyY, SurveyZ are fed with corresponding locators 3d position read out from Maya.

I make sure in every single frame, there are 6 survey points presented according to the User Guide.

I then solved the scene with only these survey points. The scene is solved in about 1 sec but the solution is terrible with out of whack scene orientation. The camera path shown in the perspective view seems close to what it supposes to be, but upside down. (Use Z-up is disabled in the Preference)

Here are couple screen cap of the solved scene and Survey Data window setting.


Any tip or comment will be really appreciated as I have been spending a week or so trying to incorporate survey data into this matchmove…..

Thanks,
Jason H.

focal length matchmover !!

hi everybody
i have a big problem with this software (matchmover)
my question is that what is init focal length ? (the blue box)
how does it work ?
i dizzy
focal length system of matchmover ir really strange ,
in capture of camera free movement (like pan) , i got different results between matchmover and boujou !
result of matchmover is very bad ( many 3d locators sit behind of camera)
and result of boujou is good (tolerable)
can you help ?:(
tnx

My track is never 100% (syntheyes help )

ive been working with syntheyes for the last month and i can never get a perfect track . i will get a good track 0.5555hpix
but nothing i can use for my shot .
i will give anything for some one to help me figure out why i suck at tracking .. is it the lens distortion or the cordinate system? i dont know . but im sure one of you do .. i will hook you up with a huge collection of sound fx that i made if you can help me out with this shot . ..

transfer a bodytrack from one 3D camera to another

Hey All,

I have a good bodytrack on a poorly tracked, nodal camera in Maya. I want to keep the bodytrack (it tracks well to the imagePlane) but have the bodytrack stick to the imagePlane of the new camera which translates rather than the nodal camera.

The bodytrack is quite complex and it’s a full body track on about 200 frames so dont want to just have to start that again on the new camera track.

Anyone got any suguestions on how to ‘transfer’ the track from one camera to another.
I have had a go with constraints and etc but I have seem to have hit a wall in figuring a way to do it.
The bodytrack has lot of movement in it and had needed the character rig to be tweaked so a solution in the 3D package would be ideal

cheers for your help!
