So it won't represent the source videotape if there's a timecode jump or reset. But the method that Dave outlines here would at least allow Matroska to mirror what happens with Aja/blackmagic capture tools using v210/mov as the capture format.

An example would be a digitally produced (in an NLE) mezzanine from a number of ingested sources, where its timecodes map to the timecods in the original sources - I've seen this used fairly often to facilitate figuring out where a particular edit may come from in a final export or mezzanine.

I would need to dig up which NLEs, specifically, produce these.
