So I have a 1920x1080 project and I want to bring in some new footage that's 1440x1080. I'm running FCPX 10.1.2 on Yosemite. Now, I'm not that knowledgeable about video editing and I'm definitely very new to Final Cut, but I can't seem to import the new footage, no matter what I try. Even making a new event or a new library/then event, the videos are grayed out when I try to import them. I tried opening them in compressor to see if I could convert them to 1920x1080, but compressor wouldn't open them. I even downloaded the free xilisoft video converter from the app store, but it told me the videos were invalid. I can watch the videos just fine in VLC or quicktime, but nothing that can edit or transcode videos seems to be able to know what to do with them. Any ideas?
