Tim puts on his producer hat to explain an import/export issue that some are calling a flicker, and he explains a way to solve it using Edit Ready. https://www.divergentmedia.com/editready

I have a 2011 iMac Pro with High Sierra 10.13.6 and FCPX 10.4.4. I was using a Canon Vixia HF G20. It is also discussed on http://www.fcp.co/forum/4-final-cut-p…

Another issue noticed the ending times are different: FCPX clip ends 10:18;03 and the Edit Ready Clip ends at 10:17 ;03.
