Go to the Capture Presets tab and scroll down until you find the first entry starting with ”Matrox  
MXO2 Mini – Apple ProRes 422 (HQ)”. Select it and click the Duplicate... button. A new window  
will open with the capture settings.  
Rename the preset to ”Matrox MXO2 Mini – 7D” and fill in an appropiate description. Then make  
sure the following settings are set.  
Frame Size: 1920 x 1080 HDTV 1080i (16:9)  
Digitizer: Matrox HDTV 1080  
Input: Matrox MXO2 Mini 1080i 59.94 YUV 10-bit  
Compressor: Apple ProRes 422 (HQ)  
FPS: 29.97  
Note that if you are running a slower computer such as the MacBook Pro at 2.66 Mhz you might  
not have the processing power available for realtime ProRes 422 (HQ) encoding and get dropped  
frames, which in turn causes the capture to fail. In that case select regular Apple ProRes 422. If you  
have a monster computer with super fast disks you might also try capturing as uncompressed 4:2:2,  
but ProRes (HQ) is virtually lossless and much more convenient to work with.  
Click the Advanced... button and make sure you set the compressor to not use interlacing.  
In the QuickTime Audio Settings set the device to None. The Canon EOS 7D does not transmit audio  
over the HDMI cable so there is no point in wasting valuable processing power on audio. Specially  
if you are on a MacBook.  
Once this is done click OK on everything until you're back in regular Final Cut Pro. You'll never  
have to repeat these steps again once your preset is created.  
Capturing Video  
Start your Log & Capture as usual but make sure you don't capture audio.  
In Capture Settings set device control to Non-Controllable Device since we can't control the 7D  
from Final Cut. It is not a tape deck! Then set Capture/Input to your newly created ”Matrox MXO2  
Mini – 7D” preset. Now you can start capturing live footage from the 7D.  
When recording it is recommended that you follow the following workflow to ease the lining up of  
the footage from the capture and the compact flash recording as well as avoiding any dropped  
frames:  
1) Once per scene: Set a good balanced exposure using the Video Scopes in Final Cut Pro  
2) Start the capture in Final Cut Pro  
3) Start recording on the camera  
4) Film your subject  
5) Stop the capture in Final Cut Pro  
6) Stop recording on the camera  
Processing the captured video  
The output from the final processing takes time and produces very large files. It is therefor  
recommended that you edit your film first and then only process the takes you really need to  
process. If you decide not to process the entire take file, but just a portion of that take make sure  
you add some head and tails to the clip or the interlace detection won't work.  
The processing will analyze the captured footage and extract the actual 24p or 25p footage from that  
stream and write it to a new file. It will also reconstruct the color channels to make the 4:2:2 capture  
into a better quality 4:4:4 file. The reconstruction is primarily visible in primary colors such as  
bright red.  
To process a clip simply take your captured footage file (one at the time) and drag and drop it on the  
7DTool.exe executable. A command-line window will open up and the rendering will start. The  
executable is only available on Windows XP/Vista/7 (for now).  
The resulting file will be named the same as your input clip, but with a _24p or _25p postfix. Before  
starting, make sure you have enough storage for the resulting file. They usually end up at around 1  
gigabyte for 10 seconds of video.  
Windows 7 only: Due to a bug in the QuickTime SDK you need to run 7DTool.exe in compatibility  
mode. Simply right-click the file and select Properties. Go to the Compatibility tab and set it to run  
in compatibility mode for ”Windows Vista (Service Pack 2)”.
