A 32Gb card holds 80 mins of footage at 50mbps (1080p 25fps) (Cameras highest quality)
Use the Canon XF Utility to back up your cards to the computer. This completes the task in about 6 - 8 times faster than real time.
It also enables you to preview all the footage (Quicktime will not)
Installing XF Utility on your edit machine also installs the plug in necessary to log and transfer footage into FCP as your choice version of ProRes.
The log and transfer process is also very quick (again much faster than real time, for me about 4 x faster than real time on a MacPro 2.8 Quad), especially if you have experienced the H264 process from Canon HDSLRs.
Premiere Pro has a specific setting for Canon XF and another for XDCam. Files can be brought in natively using the XF setting with needing to render.
The Canon website has a downloadable plug in for AVID, but I have no experience with Avid so unsure why there is a specific plug in.
Tip. Use the camera's Canon C Log scene style, it'll give you the best results in post for grading, some of the other settings are very contrasty and or over saturated. The Magic Bullet LUT Buddy plug in can be used in FCP with LUTs that you can find along with some good info over at the Abelcine blog.
