You must be disappointed when the FCP X failed to import recordings from Canon XF105. Well, don't blame to the Final Cut Pro X, the "Import from Camera…" option works just like "Log and Transfer". The thing is, even FCP 7 does not work with the Canon XF codec. The XF105 (XF300/XF305) utilizes Canon's XF Codec – a file-based MPEG-2 compression with an MXF File Wrapper that ensures the widest compatibility with existing industry infrastructure, metadata and non-linear editing (NLE) systems. The codec's 4:2:2 color sampling provides ultra-fine transitions in tone and color for maintaining the highest image quality needed for advanced post production processing. If you want to edit with MXF natively, get Adobe Premiere Pro CS5.5...Or convert the Canon MXF to something Final Cut Pro X can edit natively, say Apple ProRes 422 encoded MOV format. Here's a detailed workaround for getting Canon MXF shootings into FCP X.

Preparation
1. Transfer the .mxf clips to Mac HDD.

2. Get Pavtube HD Video Converter for Mac ($35). Click here to download a trial.

Transcode/Convert Canon XF105 recordings to Apple ProRes 422

Step 1. Launch the Pavtube HD Video Converter. Click "Add" and browse to a Canon .mxf clip and the software will add it to file list. Repeat the operation to load multiple .mxf videos.

Step 2. Click on "Format" and choose "Final Cut Pro > Apple ProRes 422 (*.mov)".

Step 3. Click "Convert" to start transcoding the Canon XF105 MPEG2 recordings to Apple ProRes / converting .mxf to .mov videos. After conversion click "Open" to find .mov videos.

Some more helpful features of the app:
1. Settings- click to set video resolution(1920x1080/1440x1080/1280x720/720x480), bitrate（from 1Mbps to 20Mbps）, frame rate (24p/30p)

2. Editor (next to "Add" icon)- click to set deinterlace, denoise, mute, volume up, trim, crop, etc.

Load/Import converted Canon XF105 footage to Final Cut Pro X

Step 1. Start up Final Cut Pro X, follow "File > Import > Files".

Step 2. Browse to the converted .mov video in the "Import Files" window. Press "Open" at the right bottom.

Now you can import Canon XF105 footage to FCP X successfully and get down to video editing. Wait- Why is there a Pavtube logo on the screen? Well, this is because I was using a trial version~~~

Tip:
Pavtube iMedia Converter for Mac can convert 1080p cameras/camcorders footages to editable HD video formats for non-linear editing software like iMovie, Final Cut Express, Final Cut Pro, Final Cut Studio, Avid, Adobe Premiere etc. The HD footage can be compressed to SD video clips for storage when you wanna save storage space. The Mac iMedia Converter is also able to extract audios from Blu-ray discs, DVDs and videos for media players with high quality and fast conversion speed.
