    Garbage matte feathering for no reason


      Hey, so I am working on a project right now which was shot on a white cyc and requires some detailed masking around some tv's. I've done several of the shots so far with no issue. For some reason the shot I'm currently working on is having some issues though. I've added a solid and matched it to the white of the cyc and made it 3D lineing it up with my track points from Boujou and started masking. The issue is that my mask is being feathered even though I haven't added any feathering yet, either with the basic feathering or the variable feathering. I've never run into this problem before and I can't seem to figure it out...I was hoping someone here could point me in the right direction.


      I thought maybe it was due to the fact that I had scaled the solid up but the resolution of the layer was still HD. But I tried uping the resolution of the layer but it didn't seem to have any effect. I'm wondering if it has something to do with the fact that I'm 3D? I'm really not sure at this point...Any help would be extremely appreciated as I'm on a bit of a schedule. I'll move on to other shots for now, hopefully someone has some ideas by the time I'm done the rest of my shots.


      Thanks so much in advance, this is my first time posting on the forums so I'm hoping for some good results!

          What is the scale level of the solid/how close to the camera is it? Is the continuously rasterize switch turned on for the layer?

            Hey Szalam,


            I'm not sure about the continuously rasterize switch (I've never used that, where is it?) But it was the scale possibly combined with the layers proximity to the camera, it was scaled about 400-500%, I scaled it back down to 100% and up the layer resolution instead and re-drew my masks and it's working fine now. I'm still confused as to why that would cause so much blur on the edges of the mask? Either way thanks for the help, as soon as I read the scale level I was like "thaaaaat's probably what it is." kind of feel stupid for not thinking to try that first. Thanks a ton!


            Cheers, Dave

              Anytime you try to scale something up beyond 100%, the program has got to try to make up information about what it would look like at that larger size. This means interpolating. Thus blurriness can ensue. The continuous rasterization button tells After Effects to keep rasterizing vector information. This means that Illustrator files (and sometimes masks) can be scaled up thousands of times and still remain crisp and clear.

              More info on the continuous rasterization button here.
