every time I try to import files it takes forever and doesn't show up (mp4 files)
mp4 is no 'format' but a wrapper.
what codec is inside this mp4?
probably it needs conversion BEFORE import.
(FCPX doesn't support any codec).
MPEG-4 is not a supported file format. The media needs to be rewrapped or converted to QuickTime, depending on its exact specifications.
@ Tom Wolsky
How does one do this using Compressor or Final Cut Pro X?
Depending on the exact specs of the media you open the files in Compressor and convert it to QuickTime. You might try MPEG Streamclip as well.
It will not open in Compressor. I get an error and it refuses to open the file. I get the exact same reaction from MPEG Streamclip.
Is there anything else?
