I just bought a brand new sandisk 'extreme pro' 32g card, and set the camera on a windowsill trying to record a jar. It still stopped recording after a few seconds. It has done this with the last three cards I've tried in it. This is pretty much a brand new camera.

Wow, really?

seems like a pretty random (but apparently widespread) phenomenon. The obvious fix would be a firmware update that allows one to choose whether or not the camera aborts or reduces quality momentrarily if the card can't keep up. The camera is completely unreliable for professional use, even as a backup, until this issue is resolved. I usually keep this one on a tripod as a second angle and use a MarkIII for the main shoot, but a lot of good that's going to do if it aborts recording the moment my back is turned! The card I just tried out in it is theoretically the best available, so that can't be it. And it isn't a motion issue, cause like I said, I was recording a closeup of a jar....

This is extremely enlightening. Yeah mine does the same thing. I'll record me playing piano or something and it'll cut out within ten seconds. Yet soemetimes it works, this makes it extremely frustrating.

perusing the interwebs a bit more, i decided to give magic lantern a try. Seems to be working. (There goes my warranty). Also changed the framerate from 29.97 to 24, but, really Canon...if you're going to sell me a camera that claims to record 1080 29.97 on an sd card you should either sell it with a BIG disclaimer or provide cards that you know will work.

Im not really sure if this is any new information or not but im having the same issue. "SanDisk Extreme PLUS" that writes at 80MB/s. For some reason it seems that when shooting in 1080p 24FPS that once it hits about the 4 gig mark in video size it stops recording. I would be fine with this if it immediately starting recording again (Just starting a new file like how GoPro s does) but it just completely stops and i have to go and get it to start recording again.

Sorry for bringing up what is possibly an old thread but this is a really frustrating issue. Especially for a camera of this quality.

MajBurke,

It is normal for the camera to stop recording at 4GB. Due to file system limitations, each clip that is recorded cannot exceed 4GB.

It's not obvious why those file system limitations should prevent the camera from immediately starting a new file and continuing to record. If, as MajBurke asserted, GoPro has made it work that way, one would think that Canon could as well.

Although I understand that write speeds and what not can cause these kinds of limitations it would be nice to see maybe a firmware update that resolves this. Maybe this is an issue that is not seen in the higher spec cameras. I just feel that this limits people on things like timelapse footage and what not.

The solution (other than just starting a new file) may not be simple. 4GB is a magic number in the Windows world. I believe it's the maximum file size in the FAT32 file system. To go larger, you'd probably have to format the card with the NTFS file system, which the camera might have to be told (via a non-trivial firmware upgrade) how to support. I don't have a card here at work, so I can't just pop one into a card reader and see what file system it uses. But you could do the exercise at home with any Windows computer. If it's FAT32, that probably explains the limitation.

Even if you could get the camera comfortable with NTFS, you might have a problem with the computer itself. Some tablets, Notably the Surface Pro 2 and 3, have rather limited support for NTFS on USB devices.

Magic Lantern so far has done the trick, by allowing me to slightly lower the data rate. It also has a tweak that will automatically start recording another file if one stops, though I haven't tried to see if it applies to the 4gig cutoff too, no reason it shouldn't. That is still clunky, since you obviously lose several frames inbetween files, but since one should be using two cameras anyway, shouldn't matter too much.

Canon should just give the magic lantern guys a bunch of money and buy their app. Way better than what you get with the off-the-shelf camera.

I'm having the same issue. Bought a new t3i just to bring on my recent African Safari. When I try to record a video, buffering meter would pop up and would stop recording automatically after a few seconds. If I try a few times, it would eventually record. Would of course happen at the worst time, so I missed a few video opportunities, what a disappointment! I'm already using a Sandisk Extreme card so I don't think write speed of the card is the issue...any other suggestions on how to fix this without installing Magic lantern? Should I try reducing resolution to 720p? Or should I just try buying another memory card? Don't want to waste more money than I need...

Re: T3i- Movie recording has stopped automatically

dpalkowski — Sun, 21 Dec 2014 07:05:05 GMT

I tried 720 also, no difference, since the data rate is the same regardless. As far as I know the only way to lower the datarate, which allows the camera to write fast enough to the card, is magic lantern. I've brought it down to 0.9 and haven't had an abort since.

I find this answer puzzling. I have several FS200 video cameras and they have no problem recording many files automaticfor two hours and more. Obviously the intermittent and brief operation of the EOS T3i 0-600D and othere DSLRs makes this feature nearly worthless. Is Cannon really saying that they won't fix it. I know I have spent many hours trying to fix the problem by switching cards, reformattind and retesting with no resolution. This may be my last Cannon DSLR if this is so.

but, as said, one of the other nice features about magic lantern is that it will automatically start another recording if the first gets aborted, either due to filesize or because of any glitch. That can be a life saver.

Although it is a frustatration, Magic lantern is a great way to get that kind of recording. Has many features that make it work your while. I still don't think I'd leave Canon for it. But that's just me. Once I had ML on there I was back to zero issues with the camera since the whole recording stopping thing was my only gripe
