    3D Camera Tracker Issue - Changing Solve Methods after a scene is done

    ryane96958443

      Hi there - I've 3D tracked a scene and put a bunch of text throughout and I'm noticing that the text is not firmly planted in the 3d space...meaning it shifts a bit as the camera rolls through the scene. 

       

      After I finished, I noticed that my Advanced > Solve Method was set to Auto Detect - which gave me an average error of 2.14 pixels.

       

      My question is, when I change the Solve method to Mostly Flat Scene (which changes the average error to 1.77 pixels), do I need to go back and redo all the 3d text layers or is there a work around for this? (There's a lot of text).

       

      I am also assuming that this may help to solve my problem of the shifting text?!

       

      Does anyone have any ideas??  Thanks!

          The camera tracker only adds keyframes to the camera. That's the only thing that is animated. You just need to add a new camera and see if things line up. If they don't but are close you can manually reposition your layers but it may be wiser to set a new origin and ground plane and then redo the 3D objects.

           

          BTW, if it is long shot - longer than 4 or 5 seconds, and you have things going in and out of frame its usually better to cut up your shot into separate pieces and track each section separately. You'll get a better solve and even though you may end up with 4 or 5 cameras in your scene, you'll spend less time fussing with things. I recently camera tracked a guy and girl walking down the sidewalk in old town Sacramento and had to replace signage in 4 store windows and a couple of lamp posts. I cut the 33 second shot up into 6 separate pieces, made each a separate comp and did them all separately. There were several overlaps so I turned off the footage layer in all of the nested comps and just laid down the original footage in the main comp. Everything matched perfectly on a shot that absolutely would not successfully camera track if i tried to use the whole shot at once.

           

          Hope this helps.

            It does.  Next time I'll be taking the approach of breaking it up I think.  Thanks for the response!
