How to remove aliasing from two images displayed on top of each other in the video sequence editor? I have two images that are displayed one on top of the other in the video sequence editor:



Each image has an accompanying transform to apply scale and rotation:



On closer inspection of the rendered output of the first frame, I discovered a lot of aliasing where the two images overlap:



The Blend property of the top two strips is set to Alpha over and the other two strips have the value set to Replace.

How do I remove the aliasing so that there isn't such a visible seam when the images are blended together?
This seems to be a precision problem, when you check Convert to float in the filter tab of your image strips, the issue disappears.
