I've been working on some videos for a non-profit and they gave me an external drive that had a bunch of footage a guy had come and shot for them on the Canon XF300. I'm not sure if it's due to how he stored his footage or what, but I cannot open in it FCPX.... Each clip has its own folder and when I go into the folder I have 4 file types. .MXF (which is the only "video" file. I can only view it in VLC) .XML .SIF .CIF the SIF and CIF files I can't even open. Any tips on how to get this working would be appreciated! I'd like to be able to use this footage on this project. Thanks!
