I'm confused. I just use Vegas. Easy as pie to line up audio. And drift Shoestring? Never had it. You must be using all sorts of funky framerates and formats if that is happening. JMO.
all my cameras shoot AVCHD 1080i60, but each device has an internal clock and they arent exact so you will see a few frames of drift on long shoots.
Easy as Pie? how long do you think it would take you to synch my current project:
10 performances, 5-6 cams each, over 100 files
Plural eyes is a life saver on projects like this
