Render alpha without black matte

[stezza]

We are rendering very small icons the antialising from pixel to alpha has a black matte, can this be avoided at the render output stage.
We can take it out in After effects or photoshop but do we have to?

Thanks

Disabling the AA filter will help to remove those pixels, but will affect the entire render image. I think it is best to do this in post.
