The other issue is that when there are only 2 motion samples and there's deformation blur, Karma (and other renderers) will interpolate vertex positions linearly between time samples.

Something that slipped through the cracks. Good suggestion. Thank you.

One of the big culprits is the OIIO stats (with high verbosity). We added HOUDINI_OIIO_MAX_STAT_LENGTH in a recent daily build (21.0.462) to cut down on that info.
Is this what you're experiencing?

You can also decide what data gets written to the metadata using a custom UsdRenderers.json file if you want. See the husk.metadata section.
