+- **Engine:** Sub-frame multi-sample motion blur. For each output frame the capture path seeks the timeline to several sub-frame times across the shutter window, captures each, and averages them. Because it re-renders at every sample rather than offsetting copies of an element, it integrates rotation, scale, opacity, filters and child animation, which the motion-blur catalog component cannot do. Defaults follow After Effects: 16 samples, a 180 degree shutter at phase -90, averaged in sRGB, with linear light available as an opt-in. Static frames still cost one capture, so only moving frames pay for the extra samples.
