ID 458020 - [S] From SBP: Transitions cause Sequences to be longer in Flix

Problem summary
Transitions in Storyboard Pro rely on an overlap between the Mark Out of the clip before the transition, and the Mark In of the one after. This overlap is not taken into consideration by Flix, causing the Sequence Revision to be longer. The exact number of additional frames present in Flix will be the sum of the durations of all the transitions present in SBP.

This becomes particularly problematic when there is audio, as it will be out of sync.

Customer reported version
Flix 6.3.4

Steps to reproduce

1) In SBP, create two shots/scenes containing one panel.

2) Add a transition between the two shots/scenes (Storyboard > Add Transition) and make it last 10 frames.

3) Import the SBP project to Flix. The Sequence Revision generated will be 10 frames longer than it should be 

Expected behaviour
The Sequence should be the same duration.

Actual behaviour
The Sequence is longer in Flix. Each panel maintains its correct duration, but instead of overlapping slightly like they do in Storyboard Pro, they are one after the other.
