Many people have asked me about CF card requirements for shooting video on the Canon HDSLR cameras. Compact Flash cards come in many speeds, and the faster they go the more expensive they get. Canon lists the data rate of the Canon 5D Mark II and 7D video modes at a maximum of 330 MB/minute (a bit less for the 5D Mark II). That’s 5.5 MB/second video, which can be converted from MegaBytes to Megabits (1 Mbit = 0.125 MByte) to 44 Megabites per second. So what speed cards do you need? Well, to be safe I suggest cards with a minimum transfer of 8 MB/second, and there are many of these cards on the market at very affordable prices. You may see CF cards listed in X values (40X, 60X, ect), so to help you decode I have provided the following chart.

Rating Speed (MB/s)
32x …………….. 4.8
40x …………….. 6.0
66x …………… 10.0
100x …………. 15.0
133x …………. 20.0
150x …………. 22.5
200x …………. 30.0
266x …………. 40.0
280x …………. 42.0
300x …………. 45.0
433x …………. 65.0
600x …………. 90.0
666x ……….. 100.0

We often sell the Transcend 133x cards in 16GB and 32GB flavors, and they have been working well for most of our clients. The big difference in card speed really becomes the ability to download the video off the card faster. A 300x card will download to a PC much faster than a 150x card. There is a chance that some cards will just not work with the camera, so make sure to test before shooting.
