I'm new to final cut pro so I don't know a lot about it. I've imported some mp4 footage and some avi footage and both of them bring up this error message when I place them in the viewer & also when I place the footage on the timeline too. How do I get rid of this error message? I read that the mp4 format can't be read in the viewer and that you had to use the compressor so it can be read. I went onto to the compressor and it completely baffled me. So if you know how to use compressor then please reply too, although I'll need instructions that are simple to understand =) Thank you in advance.
