Fast Previews: Proxy and Auto-Proxy Mode

I'm wondering what the status is on this. Is it implemented under the hood in v1.004?

By the way, Digital Fusion has a really sweet and highly interactive proxy system, which seems very much worth looking at. It has a Proxy mode, which only renders every N-th pixel of an image (with N being defined by the user). On top of that, the Auto-Proxy mode kicks in while adjusting controls on tools and even further reduces the samples taken from the image, thus making it possible to preview interactively while tweaking. While you can literally fly through most PAL composites at High Quality with Fusion, this really starts kicking ass when you do 2K comps and up.
Now, something similar to this would be a lovely thing to have in Filter Forge, and really speed up tweaking out large filter networks.

Ok, so I guess what you are refering to are under-the-hood speed optimizations. But what about a user-controllable way of speeding the previews up like in my example above? Some sort of interactive, adaptive degradation of the render quality that kicks in while you are tweaking parameters?

When the proxy is on, you see this notice:

The adaptive degradation wouldn't work with bitmap-based components like Blur, Sharpen and HighPass -- yes, you can render them with degradation (every nth pixel or so) but you still have to render their input (the image to blur/sharpen) in full quality.

Hey Vlad, is there any shortcut key to switch between them?

Maybe in the next update we would have a checkbox on the side of "[ ]Show Original" checkbox or a single key (as TAB key) to switch between them.

That should be in that "tip" thread that I don't remember where it is. Thanks for the tip Vlad, I didn't know that would work for any menu. Anyway, you would add a shortcut or check box for that in your todo list. I missed it and I felt it can be used very often to adjust stuffs before rendering the final one.

Cheers.

For the sake of consistency, maybe the Preview Size options from the View menu should also be integrated into the filter image context menu?

Vlad, that's totally hot now...
