im a newbie in MM and im having a hard time making coordinates? can someone help me on this proj im doing... i already know how to set points and already solved for camera.. but when i do the coordinates i dnt really know what to do? i already read and tried to do the tutorials but cant seem to get the hang of it.. i hope someone can help...  
 
this is the link of the video i did.. but i only got a picture to show the tracked points.. http://i18.photobucket.com/albums/ [...] /floor.jpg
 
i understand that there has to hae an origin that is on the floor and all that what is written in the tutorials.. but still i dnt understand it..sorry for the ignorance..

Hi,
What is your version of MatchMover exactly ?
Can you just send your project file (.mmf) so we will show you the best way to do that, depending on your version, as several solutions exist.
You can use tracks to define the origin and axis, or you can use a 3D manipulator, or directly move and orient the ground floor grid.
Thanks

this is the url sir... http://rapidshare.de/files/15465832/2.mmf.html
 
my versions mm pro 3.0
i cant actually relate to what your saying sir.. i chose a track point to define my origin..bt how do i know that that point is the right origin? what i read in the tutorial i can take any point as long as its on the floor to be my origin. im sorry for the ignorance..  can u like tell me what origin and axis to be used in my proj and tell me why?  me i only used the points on the ground which is 13 14 15 16 i think.. bec thats how i understand it..

Hi,
 
You can choose the point you wish as the origin, regarding where you want the grid to be positionned.
In your case, you can either choose three points on your ground (points that match the ground in the footage) to define x and z axis
or
You can choose two points to be your z (or x) axis and choose a third point to define the up-axis (y).
For instance, here is a possible solution:
- origin: Track 07
- axis 1: Z from origin to Track 08
- axis 2: Y from origin to Track 02
- distance: 10 from track 07 to track 08
 
Hope it helps,
 
Niko

thanks sir for the help.. but it didnt worked...  
the track 7 is not on the ground.. i mean i dnt know how it works.. but is it okei to choose a coordinate that is not on the ground? lets say i use the track 13 thats on the ground whats next? can i choose 13 14 16 as my y axis? but i dnt know what to put on my distance and from?

Hi,
 
Find below a screenshot of what i understand you want to obtain:
- origin: track 13
- X axis: from origin to track 16
- Z axis (Y axis is usually the up-axis, it's not on the ground): from origin to track 14
 
If you don't have the same result as me with the same settings, try to re-select the origin (track 13) on the combobox to refresh the coordinate system or drag the center of the coordinate tool on the 3d view to track 13 manually.
 
For the distance, you just have to choose two points on your scene and to set the distance between them to scale the grid accordingly.
 
I don't have our footage so it's hard (impossible?) to estimate what would be the best settings for your project...
 
Hope it helps,
 
Niko

yeah i know it would be hard for you to estimate since you dont have the footage..well i just uploaded it today.. this is the link  
http://rapidshare.de/files/15536642/2.mov.html  
 
will try what you suggested sir... thank you ...  
so the from thing is any distance from two points... thanks.. how does one measure the distance from the two. i usually see 20...  
but with a y axis i should have to use 3 points right? and 1 or two points for x or z axis? i hope im right..
