Interesting, Thanks for the link!
Well I don’t know if this is standard FCP procedure or not, but I went ahead and transcoded all my footage into ProRes in Compressor, and relinked the media files manually in FCP and everything seemed pretty flawless and hassle-free! Even though the media files are simply links in FCP (as opposed to Avid), the relinking process still managed to remember and locate the specific in and out points in the previous version.
I changed my sequence to ProRes to match my newly reconnected media files, and all looks good… But is it really?
