I’ve been using the Sony x70 now for about a year. That camera records in XAVC-L. I’ve had no issue editing this codec in cc2015. However, I’ve occasionally had some “unknown failures” when exporting h.264 via Media Encoder. I’ve found that cleaning the Cashe in both PP & ME seems to be the fix.
Good Luck
