Re: [Avid-L2] Re: mask in color grade.

 

Just for a test. Of what you need is to darken some parts of the image, out might be worth trying a paint effect mask set to darken and test if that feather doesn't have banding.
You will have to remove the color correction effect and drop a paint effect on your clip.
Hope this help.

Hi Ryan.  The material was shot on sony EX.
But the problem is not the compression,  because I'm not try'n to rescue something from the dark.  In fact I duplicate a shot.  Make it more darker and mask a part of this dark in the original shot.  The problem appears in the animate when I blend it. Appeat a banding in this. Blend.

The issue may not be with Symphony or the way to are making masked windows. It may be with the media.
 
What is the source footage? If it is from a DSLR (Canon 5D) it will be H.264 and already heavily compressed, so stretching up the blacks to try and get more detail will only reveal the compression blocking. Even having transcoded this footage to DNxHD won’t fix the problem – the camera compressor has thrown out all that information.
 
If this is the case, recommend that they shoot C-log or use an external hard Samurai drive or similar.
