Hi Nate,
Like Christina pointed out h264 isn’t the format you want to work with, you need to download the EOS canon pluggin for Final Cut Pro to use log&transfer if you already haven’t. Depending on how much media you have to import I would suggest looking into some other software to import your footage for example ” The Grinder ” to speed up the process.
I import everything as Pro Res Proxy to keep the file sizes small and it’s easier to work with, and when I get to online I simply media manage my sequence and re-capture everything as Pro Res 422.
Hope this helps,
Ben
