Ok, I was capturing video into FCP 6.0.6, from a canon zr960 dv camera with no problems. Lately, I cannot capture and have been getting issues which are preventing me from doing so. Does anyone have any advice, please, I am freaking out!!
Open a new project, set the Easy Setup for that project to match what your trying to capture and see if that works. If it does, then your previous project was most likely setup incorrectly without using the proper Easy Setup, which would indicate pilot error on your part.
