Blackmagic Forum

I've played with it and while it's possible to get reasonably good masks the lack of feathered edging really hurts. If and when that can be added it will be a whole lot more useful.

There is a separate forum for Feature Requests.

Best practice is to search first, to see if someone already asked. If not, post one idea per thread with a very brief description of the idea in the thread's title.

I'm pretty sure that BM knows the magic mask would work with feathering. I'm more interested in the opinions of users who are trying to use it.

I’m honestly surprised that it doesn’t support this. If the app is generating a procedural matte in any way, it should also be able to blur/feather the edges of that matte. Seems like an oversight to me.

yea, same here, i tried it (once) thought "this is pretty much useless" and have ignored it since...

seems like an oversight, maybe / hopefully on the roadmap

Doesn't Blur Radius fulfill this?

Seems like it to me.

I think people are thinking of this as roto-style spline-based mattes where you can control feathering with splines. But my guess is that this is a per-pixel kind of deep neural network thing with no underlying splines, so blur is all we get. (And BMD has acknowledged that it's more for color and not good enough for compositing.)

kinda / sorta, but not really - needs more precision to set softness in regions, even for the squishy imprecise values that color often can live with
it's possiable to comp the orignal overtop and roto that where needed
but if i'm doing that it makes just rotoing the entire thing simpler

I think it's not really meant for rotoscoping. It's a nice feature for isolating areas with a soft border for mild corrections in grading.

But for compositing, you'll need serious tools like Mocha or Silhouette.
