Your DSLR Canon camera records just short clips in full HD mode?

Recently my niece dropped by me with her new Canon 70 D and complained about its unresponsiveness changing duration of full HD video recording. No matter which option is selected (30 min, 1 min or any other) the camera stops recording after 7-8 seconds.

We solved the problem in a moment. Yes, it happens and here is an answer: 1. The most likely reason for Canon’s or any other DSLR camera’s inability to record long video clips is that your SD memory card is too slow. 2. You’ll notice, that changing metering option in camera’s settings does not make any difference. Recording ends shortly after its start. 3. To assure this, try to decrease video recording resolution to, for example, 640×480. Check again, how does the recording proceeds. If there are no other problems with your camera, you’ll see that recording goes on and continues until its span chosen within the settings. 4. Good or bad news, but if you need to record HD video, you’ll have to buy an appropriate SD card which is fast enough to save data provided by full high definition video. Here is a list of common classes of SD cards and their purpose of usage:

Class Speed Purpose of usage
SDHC Speed Class 2.svg Class 2 2 MB/s SD video
SDHC Speed Class 4.svg Class 4 4 MB/s High-definition video (HD) recording / Full HD (from 720p to 1080p/1080i)

SDHC Speed Class 10.svg Class 10 10 MB/s Full HD (1080p) video recording and consequent recording of HD stills
