Dear List,
i wonder if anyone has come up with a way to have framewise sync between
a gem video and audio via readsf~.
Did anyone experience drifts on a 90min video that way?
To me it seems like the only way to achieve this is to have a message
clock running both readsf~ and the gem movie player.
Or to use block~ to have the audio dsp clock as master.
Interesting topic indeed.
regards,
Peter
