What is mocha camera solve
on Apr 29, 2016 at 1:15:46 am

please explain to me what is mocha pro camera solver do never used it and now i tested it.


this is what i have done.


i tracked the side of an airline and it went well , i then copied the 4 corner pin to after effects and then added some custom text , how ever i can notice a little nudge in and out as i scroll through the scene , the airline has windows and if i place my text near the window , i use this as a reference to se if my text moves out of place and yes as i scroll through the scene i can notice small nudges .



camera solver

what i done now is pressed solve , i got 69% rate , exported to efter effects and setted the text to 3d layer and now that text is so still its not moving its like its stuck on it well even its next to the window no movements.


please tell me what does the solver do.

Well, if the corner pin seems to function not-so-well, you could try the transform option, or something like that, at least. But if the track went well in mocha but showsmup weird in AE, then it might be the corner pin option, so try messing with the options. As far as the camera solve goes, it could be that you didn't parent the trafk to a null or something? I don't have all the info so I can't exactly help..

your right i have not parented to a null , so what does that mean , does the camera layer control all 3d layers above and is the camera solve better to have objects stuck onto place

Well, you're supposed to create a null and then when you export the tracking data in mocha, choose copy to clipboard, then when you go to AE, just past the data onto your null.

Camera solvers look to derive the camera motion from the scene. This allows you to place new static objects in the scene's 3D space.

If you want to affix something to a moving object in a 3D scene, then the camera tracker is not the right tool. You'd be better off doing a standard planar track with Mocha.

Actually mocha's camera solve "can" give you animated 3D data (nulls) for a moving object, but it is probably not what you want. ;)

Here is an example of using the mocha camera solve to "solve" the camera. then using a tracked plan to get 3D nulls on a moving object:
