Custom mask feather - Boris Red

Hello

I need to help to figure out how to apply feather to a custom mask created via a spline shape in Boris Red.
I have tried to apply a blur filter to the spline track, but the result is not good enough. It creates a funny halo around the edges.
I have tried the mask choke filter but the result is even worse.

What I want to do is just like you do it in After Effects. Apply a shape to a layer - it turns into a mask - and i adjust the feather to my liking.

Where is the magical feather switch in Boris Red?

Thanks Peter

You just made me sad, but thanks anyway. :)

I'm new to Boris Red but I am already very impressed. The 3-way CC is just what we needed to do good secondary CC in Avid Media Composer.

What I would like is the feather option on the mask track, and the option to do custom mask inside the Pixel Chooser, just like I can do it in the BCC Lens Blur in AVX.
Using a blur filter to do this seems like a round trip to me. The result is simply not good enough I think.

Is it possible that you could do an in depth tutorial on the 3-way CC and custom masks?

Hello again Jeppe,

I mentioned in my last post that you could do a little compositing to use spline shapes in RED to isolate regions for color grading - here are the details:

• add the 3 Way Color Grade filter to the clip that you want to color grade
• create a new spline shape track
• use the spline tool to create the desired spline shape / shapes that you want to use to confine / isolate the color correction
• apply a pyramid blur filter to soften the mask shape and tweak the blur level
• move / nest the spline track into the host layer mask track of the 3-Way Color Grade
• select the Color Grade filter in the timeline
• in the control panel, go to the Mask tab
• set the mask shape pop-up to host layer
• enable the use host layer track switch
• set the host channel to alpha
• go back to the main 3 Way Color Grade tab and color correct the image - the color correction will be isolated to the region in the spline shape(s)

Note that you can also combine the Key function with the spline shapes to further isolate pixels in the image.

I hope this helps.

Peter.

Hi Jeppe,

I like the way you're thinking with this. Yes, we should add a Saturation slider control beneath each of the color Spheres. I'll see what can be done to accommodate that request.

Color curves are something that we have worked on a while back and I think we might have something that we could potentially add to this filter that would provide this level of control. I'll discuss it with engineering to get their feedback. If we can do it then we will, as I agree with you in that it would be a very useful addition to what is even now a very powerful and capable color correction tool.

By the way, I'm not sure if you are aware of this but we have a new Videoscope filter in the latest version of BCC 8 with lots of very useful scopes that are really helpful when color grading or color correcting clips and images ... have you tried that yet?

Meanwhile, I'll record a little movie clip going over the basics of using the 3 Way Color Corrector within Boris RED that we can upload to our web site so that everyone can benefit from this discussion.

Cheers,

Peter.
