I just got files back from a 3 camera shoot using  SONY FX 6 and A1 and a Canon C 3. All shot in 4k 24fps. When I try to link to the files, MC says under Plug-in that they can't be linked. The footage is there. All the metadata from the cards. I can play the files using VLC and I can import then into Premiere. But MC can't do anything with them. I've never quite seen this before. I've ingested footage from the same two Sony cameras from the same cameraman before and have ingested C3 footage plenty. Never seen this issue. Tried it on two different systems. Anyone have this problem or have any idea why MC is not reading these as legit files? 

thanks,

Joe

Have you tried forcing the linking to use a specific plugin?

You can select the plugin to use (it defaults to auto)
