I was wondering if there are any other solutions to checking sync in PT9 than Syncheck3. It's quite expensive and hope there is another way to do it.
Find someone local with a Sync Checker & pay them to check it for you:
It is a device with a microphone and light sensor built in, so it 'hears' the 2pop and 'sees' the flash frame - when you play a QT it can verify sync within 1/100th of a frame!
More info and results from some of their tests with ProTools configs here:
I do it by eye with a 2 pip. I rationalise this by saying that we are the ones to whom sync matters (as in humans, as opposed to machines), so if a pip looks like it's in sync, then that's good enough.
One of the problems with this is our brain's tendency to try to sync things up after the fact. I've found that looking away from the screen, so you can only see the 2 (or flash) out of the corner of your eye, helps avoid the psychological issues with perceiving sync.
I know it's a pretty cheap and dirty solution - but hey, it's worked so far!
