I have had the same issue on a couple other tests. This one is pretty close though, it would be fine if it applied the mask edge softening. I just want that hard edge from the anchor window softened. I just thought of something I am going to try, going to try and put the polygon just inside of where the anchor box ends and see if the softening will apply. Yes, Kolor hello!
Nope, that didn't work but what it did tell me is the the mask is definitely not being applied properly. Wish they were able to make the selection in step 3 the polygon - would solve my issue with this one.
i've been having the same problem with borders not being applied correctly (masking zone) haven't been able to make it fit properly..
i think it has something to do with the fact that even if you use the same lens, the video you shoot is slightly cropped compared to the still pictures so when overlaying and stitching it, it's not a perfect fit
