Some out-of-the-box FX with circular symmetry like Kaleidoscope, Polarkaleido, Bendoscope etc by their very nature tend to create a noticeable pixelation due to stretching at the centre, so I'm looking for strategies to improve it. I have attached screenshots (stills) showing the typical challenge, it's worse in running video, you can sometimes see "streams" of pixel dots heading towards or out of the very centre.
I have Wire so I can encapsulate various recipes and strategies easily (although it does not yet offer every effect that Resolume does), and then use that standalone or as a custom video effect in a Resolume clip channel. I'm not VJing, I'm just creating content in small video exports, so I have a lot of control.
I've made some progress by using a small circular mask, applying blur to that, the using a video mixer to place it back over the original scene at the centre (see screenshot of basic Wire patch). It's better than nothing, but it's not optimal, and it tends to darken the area a bit, which is noticeable when you view the entire scene.
1st screenshot shows example of a pixelated "stretched" centre area.
2nd screenshot shows example of applying small blurred circle mask.
3rd screenshot shows screenshot of simple Wire patch.
Grateful for suggestions on other ways to try to address that central pixelation.
[EDIT: BTW this is a perfect example of why sub-patching is so desperately, urgently, needed in Wire, it should not be necessary to reproduce the solution in different patches (using copy and paste) or even duplicate the solution multiple times in one patch, it "should" be possible to encapsulate such strategies as a reusable sub-patch and just drag it in with its own encapsulated controls]
