I am recording video with my Canon T2i DSLR, but it keeps stopping to say video recording has stopped automatically. I googled the problem and read that my SD card has to be fast for it to work. While I am recording 1080p at 30 FPS, I have a Transcend class 10 16GB SDHC card which makes it seem unlikely that the card is the source of the problem. Any suggestions?

Benchmark the card read/write speeds on your (or someone else's) computer.
Class 10 should read & write at speeds of at least 10 MB/sec.
For stable recording at 1080p@30fps, you probably need about 6 MB/sec minimum write speed. If the card isn't performing at its specified rate, then this could be your problem.
Two things come to mind:
- Check your owner manual to verify your card is compatible with your camera.
- then, go to the card maker website and search cards for highest transfer speed for your camera.
This should help you to rate your card.
You'll find higher transfer speeds cost more money. Example: 95mb transfer speed for my camera was $60.
