I have some problems tracking fiducials during movement. i didnt had this problem when i used my webcam as video input. but i am using a dv-cam right now… and it only recognizes fiducials when they are still.
a friend told me that i could be because of the (de)interlacing. but i dont know much about this… tried to use the videotexture (ex9 VMR9 YUV mixing mode) node to change the interlacing. but this doesnt work as soon as i connect the fiducial tracker.
