It’s in the ProRes file taken transcoded from the camera footage (Sony FS-700)
I’m not sure that this is the issue here as Activity Monitor shows 15-18MBs when playing.
This morning the issue seems to have gone away but is bound to come back…
All was working fine on Saturday. Only after booting up yesterday did the prob appear. The project had already been sent to client as a first draft.
While this is the first time I have seen the sound cutting out (again, with levels displaying correctly and no jump in video) it seems to be symptomatic of a larger problem which appeared when I was deep into another project ( before .8 but I think after .7):
While the skimmer works fine, I am getting a beachball for a good 3 seconds when hitting the space bar ( and far longer if I hit J (play backwards)). This happens after trashing prefs and logging in as another bare bones user.
I cannot be sure if the problems are interrelated but the other project was canon eos and chroma (which, hitherto, I thought was the problem…)
