Has anyone had experience insert editing to Sony's XDCAM HD PDW-F1600 unit? We work on a daily television program were we need to layback hour long audio masters from ProTools to the disc, replacing rough mix audio. The manual states it can happen but we are having challenges. We are trying to avoid the step of taking it all back into FCP and mastering a new disc as this ties up edit suites just for a layback. Any thoughts?
