@argyleink the Skottie implementation linked above is not based on box blur, but on frame averaging: we sample multiple frames on the timeline and compute the result my modulating/blending these frames. You can see the effect in action here: https://skottie.skia.org/718e3d0979791b0c268efe68c10056a6?h=500&w=500 This is pretty close to the physical model, and also what AE appears to be doing (there's a separate Pixel Motion Blur effect which computes inter-frame per-pixel motion vectors, but this is about the basic MB switch). This approach has a couple of nice properties: - doesn't require prior animation/transform knowledge - doesn't require/assume static content (adapts to content changes naturally) The downside is obviously a multi-frame buffering requirement. -- GitHub Notification of comment by fmalita Please view or discuss this issue at https://github.com/w3c/csswg-drafts/issues/3837#issuecomment-520521445 using your GitHub accountReceived on Monday, 12 August 2019 17:36:40 UTC
