[Kdenlive-devel] Feature for kdenlive....

Wed Jul 2 04:14:00 UTC 2014

Evert,

I made the changes but am awaiting dev-access in order to push up my 
changes.  I can not test due to the fact that both of the existing 
stabilizers crash on my machine.  The new one crashes too :-)

But, if the pattern used to implement the existing two stabilizers is 
the same for the new one then I think I have it sorted out.  I'll need 
you to test it for me.

If you want I can attach the two source files if you are anxious and 
don't want to wait.
