I have two images that are displayed one on top of the other in the video sequence editor:

enter image description here

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

enter image description here

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

enter image description here

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.

  • $\begingroup$ I wonder why this isn't the default? I am maintaining an addon for transforming strips in the VSE and I wonder if I should make my addon ensure this box is checked whenever a transform strip is added $\endgroup$ – doakey3 Feb 28 '18 at 2:18
