Vlad Kuzmin (Ssh4) added a comment to T82645: Tracking: unify data storage for camera intrinsics.

I've never had to animate a lens distortion, and I'm still not entirely clear why anyone would do that. If the camera does a zoom, does the lens distortion change and that's what you're trying to solve? From a VFX point of view, are there any instances of animated lens distortion in any movies or tv shows that anyone can point to? I've cetainly never had to deal with one in my work.

@Sebastian Koenig (sebastian_k) @Ivan Perevala (ivpe) @Sergey Sharybin (sergey) as soon as we touching Movie Clips. Video can be captured using zoom lenses as well as using optical or sensor stabilization, that mean lens intrinsics can be changed per frame. And even if current tracker code is not allow tracking such footage, external trackers, especially photogrammetry based (including opensource tools) can give such data. That can be imported to blender in Movie Clip. How in that case we can store per frame camera intrinsics in a future?

Oct 21 2020, 2:22 PM · BF Blender (2.91)
Vlad Kuzmin (Ssh4) added a comment to T81662: Camera projection mapping for brush texture.

For example, distortion model does not exist on its own. It is highly coupled to a specific camera and its configuration used when shooting a footage. Currently such coupling exists in the Movie Clip datablock, with tools to estimate the distortion model done in Movie Clip Editor.

From this point of view, it seems logical to build a workflow based on use of movie clip datablocks. This solves the problem of non-reusable parameters stored in brush datablock, and solves problem of adding parameters to camera which are only usable by painting.

How from artists, matte painter, or accets creator point of view images that use camera view as a projection (we can name them Projector Projection that is more like a Light with color gel on it) images are related to Movie Clip? Or you only about datablocks, not about UX?

Vlad Kuzmin (Ssh4) added a comment to T81662: Camera projection mapping for brush texture.

Be aware that design decisions need to be approved by reviewers and module owners. So you can of course to implement it however you want, but it's won't necessarily be accepted that way.

Can you clarify this point? @Ivan Perevala (ivpe) definitely can’t make own decision on final design. And If you know any plans in upcoming changes in this module please share them to Ivan.
If someone already working on refactoring this area in Blender and that code can interfere with that refactoring, we definitely need to bear in mind that upcoming changes to make this work usable in them too.
But if there is no plans for near future, and no Blender foundation coder[s] assigned to that tasks, Ivan as independent coder can only add new feature with maximal compatibility with existing code and current blender user experience.
Also sorry, English is not native for us, and ultimate word “decision” just mean, opinion that such way is more usable. :)

@Brecht Van Lommel (brecht)
Definitely for this moment camera projection is not so usable without preview.
And @Ivan Perevala (ivpe) have this Milestone 3 Preview.
Only issue that Camera Projection can be used without preview. But have preview without camera projection implemented have no reason. So this is only matter of priority.
And for this moment when code for camera projection is working, and we can brush up UX for this tool.
