Joining 2D tracking markers with an offset Is there any way to join tracks with an offset (like can be done in After effects)?  I'm looking for a way to create a gap less 2D track. (It will be used only for 2D stabilization) 

This is an example showing the situation in the footage.


Here are the two tracked marks that get blocked by a pole at different times.


I want to be able to use the tracking data from the black mark when the red mark is obstructed.


However if I simply join the two tracks there will be a jump in the path.
To track areas that are blocked by obstacles or temporary going off-screen. Move the tracking marker before the area is hidden by pressing GG and dragging the marker to another tracking point, or offsetting the marker in Track properties panel in Marker section by changing X and Y offset position. You can then continue tracking the scene under the offset tracking area until the original tracking area is visible again, then move the marker back using the same procedure.
