when rolling, sure. i'm thinking about a locate command.
its also true that there are variants of SMPTE that include subframes,
which certainly help the accuracy, but its not clear to me how
commonly this information is actually passed around.
SMPTE is a low resolution time code. There is no
reason to be limited
by frame rates of 30 fps when defining a synchronization protocol
between applications running on the same (or even two networked)
computer(s). JACK transport is sample-accurate, and as such is
thousands of times more accurate than SMPTE.
While I'd agree 100% that SMPTE is not what's needed here,
your comments on its potential accuracy are misleading.
The *data* contained in the SMPTE timecode is quantised
to frames. But SMPTE is not just that data. It is data
encoded into an audio signal, and this can be resolved
to sub-microsecond accuracy.
