The jump you see is most likely due to incorrect presentation times assigned
to the clips (or images) or incorrectly assigning tracks. If you create a
new track for each transition, there could be quite a few tracks causing
loading delay. The solution is to use just two tracks and switch the
direction of transitions

The best way is to write out the timeline as an XML file and verify that the
transitions are correctly rendered. The presentation times should follow the
structure below for a transition going from Track 1 to Track 2 (I hope the
ASCII diagram comes out properly).

-----------------------
| Track n clip |
-----------------------
| Tran |
-----------------------
| Track n+1 clip |
------------------------
