These non stop bugs are a huge problem and ones that I've had since last May's update. Fergus reached out and said he would personally help me. I sent him an entire card of MXF files from my c300 mark iii and the C70.
He said he couldn't recreate the problem and then I lost all contact with him. There is no solution to this problem and Adobe refuses to fix it. So I am moving to Resolve and ending my subscription. I am so astonished that they are just letting this happen. Every profesional I know in the industry is leaving or has already left. That is a crying shame. The end of an era. Your profesionals have left.
