Why does my DSLR automatically stop recording.?

Question

Does anyone know why would my DSLR automatically stop recording? Have this ever happen to you? I did some research, says the SD card writing speed is not high enough to write the data, a class 6 or higher level would help, but my card is level 10! why? and there are suggestions about formatting the card, I tried, didn't help... please help me..

Answer 1

There's a variety of reasons...

1. The memory card may be full.



Are you talking about photographs or video?

2. If it's photos, then the buffer may be full - if you are firing off shots very quickly, then the buffer will fill up. Learn to shoot more carefully.



3. If it's video, then there is a limit to how much video you can record in one go (normally it's 4GB on most dSLRs)



4. What brand of memory card are you using. Class 10 is meaningless if it's a cheap brand. You want to look at continuous speed, not burst. That's why most of us who take a lot of shots buy Sandisk Extreme or Lexar Pro cards - and never off eBay, as there are lots of fakes on there.



Some of the information on Rob Galbraith's website is a little out of date, but the general data is good - they may not have your particular camera, but here's the Canon 450D, which also takes SD cards:

Check your manual to find out what the maximum recording time is for your DSLR. It is not indefinite, and probably 30 minutes or less.



The issue at hand is that while DSLRs are capable of high quality, they are still primarily for photos - not videos. For that reason the sensor overheats after a certain period of time, and the camera may be shutting down to protect itself.



This is not usually an issue in most video as scenes are often short durations, and the video is comprised of many scenes stitched together into one. However, if you are simply putting your camera on a tripod and recording people walking by for an hour, realize that most photo cameras (if not all) will stop long before that hour.



The length of record time is the one advantage that CamCorders still have over cameras, but even then, they are not indefinite either.

Answer 3

the digital part of digital camera means it stores data as digital files on the memory card. all digital cameras stop recording video when the file size reaches either 2 GB or 4 GB in size, which is approximately 10 minutes of continuous recording. most dSLRs use the 4 GB limit, but that requires you use the USB cord to download to computer as most SD card readers can't handle a file over 2 GB.



a camcorder can record continuously because when it nears the 2 GB limit, it automatically closes the file and starts a second one in sequence. Thus when recording a long event, like a wedding, the video will be segmented into 2 GB files. The camera software, and video editing software understands sequential file structure and makes it transparent to the user. However some people try using their computer file manager to download files manually and are shocked to see a whole series of files instead of the one event they thought they shot. But if you think about it, a one hour video with a 12 GB file size would be difficult or impossible for any computer to manage as a single file.



most digital cameras find a class 6 card to be adequate for video, although a few top end cameras recommend higher class cards. dSLR cameras also have a temperature issue, and most will over heat in 30 minutes or less of video use. this makes dSLRs impractical for recording continuous events like wedding ceremonies and school plays. The reason for the heating problem is a dSLR is designed to imitate a film camera in appearance. This puts the CCD sensor against the rear of the camera and impossible to properly heatsink. A camcorder and most P&S cameras have the CCD in the center of the camera.

Answer 4

Get a new card if it's persistent.



I've had it with a class 10 card before now, intermittently, then it works fine.



I suspect that the write capacity of SD cards is approaching the limits when saving video files and any small time lag will stop the recording. SD cards are solid state devices that don't last for ever. If you've had lots of write cycles then it's possible the performance is reducing.

Answer 6

I used to think that all class 10 cards were equal - they are not!



I was given a 32GB Kingston class 10 card as a gift. It cannot keep up with burst mode on my EOS450D shooting RAW + jpg. - 4 shots and it has to stop shooting while the card catches up.



With my usual cards (Sandisk Extreme Class 10 - recommended for HD video) I can get 5 shots in burst mode then the rate slows a little but carries on taking to 9 - still going but I don't need that many shots!



I did a write test in the SD slot on my laptop - the Sandisk wrote a bunch of test data in 10 seconds. The same test data on the Kingston took 18 seconds.



"Class 10" is pretty meaningless as far as I'm concerned.



Try these cards:

I use the 8's as I don't have video, they also do 16 and 32's

Answer 7

This is according to EU law. There is a tariff on all digital video cameras that can record continuously for more than 30 minutes. Most camera makers wish to sell one model worldwide, so they force shutdown before 30 minutes. Some makers use the excuse of heat to cover for this and prevent consumer lashback. Long ago, file sizes or SD card formatting were also factors, but that is ancient history. Panasonic/Lumix is one vendor that bypasses this issue (records indefinitely, or until the memory card is full). I think they get around the tariff/legal issue by not supporting PAL format. Presumably PAL compatible versions of their products sold in the EU have this 30 min limit. But the rest of us can be happy.

Answer 10

They all stop recording after a few minutes. It will also stop recording before the maximum time allowed by the manufacturer if the camera gets too hot.

Answer 11

All I can suggest is try another Class 10 SDHC card with the highest capacity you can afford, preferably another brand from your existing one. There should be no difference but sometimes some cards just don't do it.

Answer 12

perhaps your camera is limited to certain length clips ie 1 minute, 5 minute etc.You have given no camera details in your question so at best we can only generalise.

Answer 13

You would be better off using the U1 class of SD card. I have this San Disk card and have no problems with it at a burst rate of 7fps for 100 pics or video.
