If you set this to something other than all or none, you can use the checkboxes on the right to select individual channels.ĭisplays the GPU used for rendering when Use GPU if available is enabled. The effect is only applied to these channels. If you cannot see the mask input, ensure that the mask control is disabled or set to none. By default, the blur is limited to the non-black areas of the mask.Īt first, the mask input appears as triangle on the right side of the node, but when you drag it, it turns into an arrow labeled mask. This should also contain the depth map channel.Īn optional image to use as a mask.
The image sequence to receive the blur effect. You don’t necessarily need to crop the filter image to a smaller size, as Fast Fourier Transforms are used to speed up convolutions with large filter images.
For example, if you want to add color fringing to your out-of-focus highlights to simulate chromatic aberration, you can use the Flare node to easily create a suitable filter image. The filter image can also be a color image. You can create a filter image using the Roto node ( Draw > Roto) or the Flare node ( Draw > Flare), for example. As the clip in the image input is blurred, any out-of-focus highlights (’bokeh’) in the clip assume the shape of the filter image. It represents the shape and size of the camera aperture used to shoot the input footage.
This allows it to preserve the ordering of objects in the image. After ZDefocus has processed all the layers, it blends them together from the back to the front of the image, with each new layer going over the top of the previous ones. In order to defocus the image, ZDefocus splits the image up into layers, each of which is assigned the same depth value everywhere and processed with a single blur size. This allows you to simulate depth-of-field (DOF) blurring. Blurs the image according to a depth map channel.
