I was doing an edit using MXF camera files from F55 camera. Shot in 4k and dups in 2k. Did my offline in 2k and used some 2k only 60fps slow mo. I had a bug in windows which meant I had to reinstall the Vegas software. Now back in the project time line those 2k 60fps media are off line and I can't access it in explorer window. Those files ar all whited out in Media bin as if it's a non compatiable. I checked on sony browser and the files are defientwly there and play fine. Just can't put the files back into my time line. Thought it something to do with preferences or settings. But I didn't change anything since the reinstall. Anyone have any clues. Hope someone can help . Thanks. Alan.
