How do i import HD videos

I'd have a cunning, albeit somewhat treacherous, plan: IIRC, Premiere Pro can read that Canopus codec. Download the Premiere trial version, make a new project (PAL DV, Pixel Ratio 0.91, 16bit audio), import your footage, drag it into the timeline and export it to ProRes.

Or simply run it through Media Encoder.

That should give you the least quality loss.

In FCPX go to preferences.
Under playback uncheck optimize media and the one right below it. You should see your files.

Thanks everyone, i've exported it to h.264 using mov container.
and i've moved it to my desktop first, then imported it into FCPx.

THAANKS!
