t2i-t3i 'Movie recording has been stopped automatically' in bright scene.

Using a Class 6 Transcend card, I got the error message 'Movie recording has been stopped automatically'. Googling revealed that this is a buffer issue.. I'm getting better memory cards.

But here is the question:

I've used these cards on my HD camcorder.. I figure the t3i might be capturing more data.. What I don't understand is why does it happen with bright light, and with blown out light in the scene? I was shooting a low light interior shot just fine last evening, but as soon as panned across a large plasma TV that looked blown out, the camera 'Movie recording has been stopped automatically' error-ed.

I just want to make sure it's not something else.

Thanks for the help.

This happened to me, numerous times, while shooting a feature in the middle of a very hot summer (T2i, and a class 10 card). As far as I can tell, my camera is not broken, and this is just one of the downsides of using a photography camera to shoot video. Cest la vie.

I think that the overheating is in the camera itself rather than in the card.
Yes, photography cameras tend to overheat when shooting in summer and under other kinds of heat realated stress, but I guess the situation is pretty much unavoidable without some kind of insulation...troublesome insulation.

Maybe somebody should come up with a refrigeration system to put around the camera like we used to do on PCs when we overclocked the CPU, or maybe cooling fans mounted to the rails.

:lol:

As far as the overheating is concerned, perhaps I mislead, in mentioning the heat when I was shooting. I don't think the OP's issue is overheating, but they are at least somewhat related (sun is both hot and bright).

BTW, as I understand it, the overheating issue is purely a problem with the batteries. They're not designed for shooting video for prolonged periods of time. I imagine this should be an easy fix if/when Canon finally puts out something with DSLR technology that is designed for video first.

In my case, the buffer indicator pinged. The temp indicator did not show anything. I am left wondering why bright light or bright spots would need to write more data. ..or is it a hardware safety thing.

Reading up on memory cards, there are some specific cards some folks are using, apparently generic cards, or deals on cards are notorious for issues.. I hope an even better memory card can fix this.


Regarding heat, both shots were in cool conditions 65f for very short shots.. Brightness on the LCD screen was very high. I don't know if the camera could overheat due to sheer 'brightness'..

Regarding DSLR vs. Consumer Camera.. The DSLR requires a lot more preparation and anticipation to shoot with. I would take it out of the point and shoot category.. My consumer video camera is fire and forget, compared to the T3i.

holy cow, I googled.. "bright light, causing t3i buffer" and this thread just came up.. and the thread is only 35 mins old!

Well, what did the thread say? :lol:

Interesting thought about the batteries from CF. Video cameras tend to use small CMOS sensors and will increase the number of sensors to increase area instead of using a larger sensor. Smaller chips are cheaper, but I wonder if there is another reason. If there is, Panasonic has figured it out, apparently, with the AG-AF-100.

Hmm....

It's the display. The camera is intended to be primarily used with the eyepiece, which is how most photographers prefer to shoot. But in video mode, the shutter is continually open, so the eyepiece won't work, and that's why, when in video mode, you can only use the display. Well, the display uses more battery power than this battery on this camera is originally intended for, hence, overheat.

Im using Transcend 32gb Class 10 on my T2i... no issues so far. I have had some shutoffs, but I think I hit the 4gb file size limit where the cam will stop.

Dang.. have you ever pointed your camera at a bright LCD screen in a low light room?.. not that i suggest it.. My camera shuts of almost instantly.

I'm going to take a stab at this. I'm thinking this has to do with the q-scale factor of the camera. Its ability to record data at the best resolution it can on the fly. Now if you imagine recording in low light, less data, then just suddenly point it at bright light with lots of data, perhaps the sdhc card is unable to keep up with the huge data rate spike at that very moment. That's where your transfer speeds of your sdhc cards come into play along with there burst writing rate. Just my theory anyways. I too have a 32gb Transcend class 10 card, but have not had an issue yet, although I havent had it long either.

@zimm9000 ... be fun to stick a class 4 card in there and see if you can FORCE the shutdown.

I tried to force close with a class 4 (PNY optima 8gb) and had trouble force closing the buffer, so I switched to an old SanDisk MicroSD (very old cell phone card class2?) in an adapter and I can force close it every time...

Success!!.. Note, that even sounds will cause this card to buffer fail.

Here is the test.

I actually called canon on this card issue because of the original Patriot card I got was not working properly. They told me class 10 is total overkill. They said they all use class 6 with the following brands for testing: Kingston, SanDisk, and Lexar. They said everything else is hit or miss. I believe he even said that some class 4's will work just fine too. My guess is SanDisk for that one.

Wow, I just bought 2 class 10 SanDisk's because I was afraid of trouble. Dang.

Rob, sorry for you troubles, bro. I know you were stoked to get that camera. Have faith, though, you'll get that thing running smooth soon.

If your using the Magic Lantern firmware on a T2i then be glad you have them, as you should be able to max out the Q-scale and have nice long high quality video. :)
