All media. I’ve uninstalled and reinstalled MC. Uninstalled (and now reinstalled) FCP. Reinstalled the AvidCodecsLE codecs off the site. Tried different hard drives. I’ve found this: https://community.avid.com/forums/t/101094.aspx
Which is what it is doing, but I’m not sure how that can relate to my setup seeing as all my media is on external RAIDs directly attached to the machine.
Sadly no. I’ve found viewing at 100% and regular restarts is the *most* reliable way. Still a complete pain though. If I have time I’m aiming to transcode before I get it into AE at the moment.
