Problem with blur in video editing Hi i really hope someone can help me out with this: I'm trying to blur a section of my video, the part where my motorbike speedometer is, and basically i followed this tutorial on YouTube https://www.youtube.com/watch?v=_06cWLUZ_Bg BUT the thing is that no matter what ,the section which get blurred(on the right) does not correspond to the section i selected(on the left)

Because i thought it was kind of a sync problem between the "actual" video and its "reference" video in the UV/editor i selected Start = 0 (in the UV/editor properties ) but nothing changed, also by selecting Offset = 0 too.

So...what the hell is going on here? 
thanks!

p.s. If you need more details just ask.
It's because you have a different aspect ratio in image and final render. You can do 2 things:

1) set render size equal to video demissions



2) tune  aspect ratio of image in display settings in movie clip editor
