T2i "Automatically stopped recording"?

Can someone please explain to me why my T2i always stops me in the middle of a video? I'm currently using a Class 6 Sandisk 8GB card. I know it had lots of room on it, so can someone please tell me how to fix this issue?

buy faster card,its not class that matters but speed of it and how much MB it can handle,sometimes class 4 cards are faster than some class 6 cards.
 
Exactly right. I'd VERY suspect of a Sandisk class-6 card that couldn't keep up. None of my class-6 Sandisks have ever had an issue, anyty my 32GB class-4 has been flawless as well.
 
Just got a new Sandisk Ultra 16gb. This is the first one that arrived not working properly. Lots of buffer errors. I've been using the Ultras (30 mbps) with no problem on my other 4. Broken cards happen to the best of us I guess.

After a minute? Two minutes? Ten minutes? Twelve+ minutes? How big are the .mov files when it stops?
 
guys... its because of the filesystem on the cards. the maximum filesize is around 4gb (fat/fat32).
so maximum recording time on the cams using SD cards is because of their filesystem.
 
I've actually started having the oddest problem using Lexar Pro series Class 10 16gb cards (not quite as expensive as Sandisk, but not cheap like Kingston/Transcend either), speed is rated plenty fast and they seem to be on par in quality with other expensive memory.

They've been great cards, but sometimes without warning I'll get the buffer error and recording will automatically stop (sometimes as soon as 20 seconds in). Then I'll try again, and the same thing will happen. However on the 3rd or 4th attempt, it will then record beautifully until it reaches the maximum 4GB file size.
Weird, so its not really a speed issue because the card CAN record just fine to its full capacity. And its not really a size issue because I clearly have space. By why does it sometimes need to have a few "test shots" before it is ready to record a long one? There seems to be no rhyme or reason that I can tell as to when it happens, so I can't predict it. It can be very embarrassing and annoying to ask the talent to start over each time. I've tried formatting the cards as well, and switching to another card (another Lexmark Pro, identical card). So odd... what else could be causing it?
I'd say maybe the brand of card, but it seems to have a solid reputation... even then it doesn't make sense that sometimes it would work and other times not!
 
I had similar issues when I was erasing footage from the card in the camera, and then filming more without formatting inbetween. My suggestion is to start with a freshly formatted card, film until you are done for the day or until the card is full, transfer the footage to a computer, than format the card and start again. Do NOT erase some of the video files in the camera to make more room and continue filming, this can fragment the empty space on the card and cause issues.

Ever since I have adopted this workflow I have had no buffer issues.

I have the same problem here. It records for 3 seconds. I get the overheating warning then disappears. 2 seconds later it comes back and it automatically shuts off.
Its been doing that after I installed the ML onto my card. It never did that before.
 
Have you got Q Scale set to off in Magic Lantern ? Having it set to any minus value can sometimes cause this problem. I take it you mean the buffer bar rather than the overheating icon ? if it is overheating after 3 seconds it would deffo be a record
 
I also thought it was ML at first, but I only have it on one of my cards. The other card does not have Magic Lantern and did the same thing for a bit.

I'm going to try a low level format instead of a quick format and see if it makes a difference. Would be pretty annoying if I needed to do that everytime, though. :/
 
7 min. 58 sec.

7 min. 58 sec.

On my firmware hacked Lumix GF1 (PTool + Lpowell's High Reliability Patch), I can only record 7 min. 58 sec., then the video automatically stops. Happens every time. I never tried to shoot longer than 8 minutes before the firmware hack, so I am not sure if the hack is the culprit. But my SDHC card is 16GB class 10 SanDisk Extreme. Interestingly, the filesize of the MJPEG video is exactly 2GB.

Last year, lpowell said the 2GB limit had to do with MJPEG recording:

But I am wondering why this is so, and if there is any workaround for it.

For slow cards, you can try either QScale -1...-5 or CBRe around 30 mbps, with Magic Lantern. With slower settings it should be able to record even on class2 cards :)
 
em... GF1?? I don't think you'll find lots of answers on this subforum... for a start, alex's response talks about the t2i, which is the camera mentioned in the title of this thread

I don't even know if it is a filesystem issue, but, if it is, there's usually no way around it, other than alex's suggestion of recording at lower bitrate so you can get more minutes on your fixed maximum file size... which, again, I don't know if you can do with your camera

Update: yes, the cards just needed a good formatting. After that, no more buffer errors.

In the camera, format with low level box ticked, and solved all of my problems. It could come back if you delete a lot of stuff on the card, however, as that fragments the memory allocation addresses. Better to not delete anything while on a shoot, and then take all the footage off the card and format the whole thing when done for next time.
