Not our experience. My wife tried editin a 3 camera performance (1 Sony A6400, 1 Sony TD30, 1 Sony AX100) + 1 Zoom H1 audio track, and after 5 minutes editing build 636 froze (not responding). I set legacy avc decoding in preferences and so far so good. Is this a known bug with the new avc decoder? Will i loose performance when enable legacy mode? That is not gpu accelerated?
