> Would there be utility in allowing both a and an interpolation function, as a way of modifying the shape of the interpolation? Or too many curves being smooshed together...

@larsenwork If the syntax referenced the [timing-function/transition function data type](https://drafts.csswg.org/css-timing-1/#single-timing-function-production), then a `cubic-bezier()` function would automatically be included, as an alternative to the shorthand keywords.

@larsenwork Symmetrical step functions are currently being called [`frames()`](https://drafts.csswg.org/css-timing-1/#frames-timing-functions). But that is being debated in #1301 . Your fourth example matches `frames(4)`: four equally-allocated values, including both the start and...

This is definitely something I've seen asked for. I've also seen it faked (for linear motion) with SVG filters (and there is a [proposal to add unidirectional blur to the...

> I think it makes more sense as part of filter (@Martin-Pitt ) That's very similar to the proposal from w3c/fxtf-drafts#50. I definitely still support having the ability to specify...

> What about backdrop-filter in conjunction with scrolling? What's special about `backdrop-filter` is how you clip the layer image before applying the filter. But even when scrolling, you're only changing...

> Could motion blur in some sense be tied to the frame rate alongside the speed and direction of scrolling in backdrop-filter (or elsewhere) Sorry, didn't read your comment closely...

@grorg We give implementations flexibility in picking the algorithm for simple blur, so I don't think we'd want to be any more specific for motion blur. If we approach the...

That looks good to me. Other key points from the discussion, as I understand it: - The property should have no side effects; it doesn't force a compositor layer on...

> I suspect that we will need to force a compositor layer whenever the blur is applied. No, to be clear, the proposal is that motion-blur could be ignored (no...
