how we can combile 2 tracks,
 
'll explain abt my shot , its a 700 frames zooming shot in that am having  full track points but in between one window is coming(only for 11 frames) so whole track point is getting cut, how can i solve this oprob, wot i thout is like 'll track it saperatly & combine ,so is there any way 2 combine 2 camers.

Hi,
Can you pick up tracking points from the 1st part in the 2nd part? If so, just put an end-keyframe (F7) before occlusion and a start-keyframe (F5) after. If you know the positions of your tracking points while they are hidden, you may set a position with F8.
Can you put your image-file for download on ftp?
Best regards

'll explain it detail,am getting track from 1-30  & 50-end.these both areas r tacking properly.cut is coming in between 31& 49.there am not getting any track points.
1,
i tracked 1-end & selected 31-49 & excluded from the track & solved that time realviz is not giving whole duration.
2, i tracked 1-31,49-end,saperatly, and exported in to maya & add a third camera & give the parent constraint &  tried that time a big jumping getting these area.
