There are limitations to how long you can record.
Look in the Instruction Manual at pages 150 and 151.
When you format the card you MUST format the card with the CAMERA and NOT with the Computer.
See page 45 of the Instruction Manual to see how to format with the Camera.
As stated by the title, I have been having a problem with my week-old Canon EOS Rebel t3i. Now I've been attempting to record video with it, as that is the main reason that I purchased this camera, but I keep getting an error.
After recording video for roughly 30 seconds-3 minutes (Depending upon randomness as far as I can tell, as well as quality; 1080p vs 480p, etc.), it stops and an error pops of saying, "Movie recording has been stopped automatically".
Before responding, note that I have researched this already. I have a SanDisk 16GB Ultra Class 10 SDHC 30MB/s (bought in store). I freshly format the card before recording. The most frustrating thing is that it was working only a few days ago... I don't think I've done anything unusual that would cause this, but I may be wrong.
Please tell me if I left out any relevant information. Thanks in advance for your responses.
