I am using class 6 Kingston SD cards, I keep getting the "recording stopped automatically" message almost every time I shot (the buffer indicator is displayed). Should I be using even faster SD cards? Or it could be a problem with Kingston?

How much time is recorded when you get that message?

Not even two minutes, Chris.
Thanks
Subbu

I would try a different Class 6 SDHC card.

Thanks Chris; Will try a different card.

Also Subbu, what is the capacity of that Kingston card?

8GB.

Thanks
Subbu

I had a 32 gb tell me that and the card turned out to be bad.(delkin class 6) lost footage. put in another card (same type) and it's been working fine.

I got the same message yesterday with a Transcend class 10 8 GB card. Only got it once.
Card was less than half full.

just really watch those cards that give you that message...don't record anything critical or non repeatable. I learned the hard way!

I got the same thing around 13minutes into continuous shooting. File size was 3.98GB, so I thought it was hitting the 4GB file size limit or some sort. Is this an anomaly?

Euisung, the camera cannot record for more than about 12-13 minutes at a time (I'm not sure the exact length because I don't own one for this very reason)

Once you hit that limit you will have to hit record again.

The record time limit is 00:29:59;00
Any thing less is caused by something out of the camera's control.
I'm just thankful it lets you know and finishes writing the file.

The record time limit in Standard Definition is 00:29:59;00

The record time limit in High Definition is approximately 12 to 14 minutes, give or take.

It's a range in HD - 12 to 14 minutes as Chris mentions - because the actual limit is the 4GB file size. Depending on your ISO setting, that could be anywhere in this range of durations.

The following is a link to a reliable testing site (Tom's hardware) where you can find the results of some SDHC cards tested for their ability to handle a high throughput data stream, like HD video. I tend to look exclusively at the lowest write speeds when deciding on any flash memory (SD, SDHC, CF...), and Sandisk Extremes (III) are all I'd currently consider for HD video purposes in the SDHC realm. And I have no financial interest in Sandisk, in case anyone was wondering.

Transcend class 6 16gb have only given me that message when hitting the 4 gb mark- otherwise, no problem at all!

FYI

Transcend class 6 should be fine. Many EX1 users have been using these cards for a long time without any issues at all. I use them constantly with an EX1 and a JVC GY-HM100, recording 1920x1080 @ 35mbps

I got this message yesterday for the first time.
However, I was almost to the end of this particular card (16GB Class 6 Delkin SD card). As I immediately pushed record again and after only 2 minutes got a card full message.

This was the first time that I have seen this message as I haven't had a full card to date. I normally remove data from the card after each shoot.

So I am figuring that the message appears when you are getting to the end of the SD card.

I got the transcend class 6 and when I first time used, it stopped video recording immediately. I pressed the recording button and it continued recording. however, intermittently "buffer indicator" popped. Is the buffer indicator display normal during video recording?

When I retried, I had the same error. The difference is I have shot some still pcis and then recorded video. Is there such a thing that the card should exclusively be used for video recording. I am wondering that it may be my camera.

You may be getting read/write errors on the SD card. Copy all your files and try doing a couple of low level formats.

Tried two Patriot 16GB LX series class 10 cards. Both were low level formatted in camera. Both crash. The most I could get was 6 minutes, but usually it averaged three minutes before recording stopped. The buffer level indicator flashes one bar then maxes out before stopping. It flashes so quickly that I didn't notice it right away.

Received a 16GB Transcend class 6 card yesterday and no problem as of yet.

Avoid Patriot then.
Thanks for sharing.

I was getting the error message on my ADATA Turbo Class6 until I did a low-level format.
Now it's much better.
8GB Transcend SDHC had no errors. Go figure.

I have had the same problem with class 6, i have 3 32gb and none work for hd video, work fine for pics. Then i bought class 10 cards and no problems, but all class 10 cards are no equal. Be sure they are at a minimum 20 MB/S and 30+ up is better. According to Canon when i called them they said class 10 only, the faster the better

They should update the manual though. It says Class 6 and up.

I found the Silicon Image Class 10 16gb (http://www.digitalreviews.net/reviews/memory/silicon-power-sdhc-class-10-memory-card-reviewed.html) for 40 euros here and it seems a good card with good i/o.

manual states to use class 6 and above...and remember to look at that five-level indicator when it appears on the right side of the screen during shooting...the slower the card the faster that indicator climbs...it indicates how much data has not been written to the card...if indicator hits the top you get that message stating recording has automatically stopped...

Just had my first automatic stop. Thankfully, not during an important shoot.

i used a class 10 card today and all was smooth...the indicator never appeared and no auto stops...

Some T1i owners had this happen using Kingston Class (6) cards (one had it with 3 cards!). Canon advised the camera can be "brand finicky" and suggested SanDisk Extreme III.

That solved the problem. Nikon D90 sometimes did the same thing, again SanDisk Extreme III did the trick.

That is not normal for a quality properly functioning card.

Your Transcend Class (6) is trying to do the same thing to you the Kingston Class (6) did, just not quite as bad. It will let you down when you can least afford to have it do so.

Patriot, A-Data, Delkin, and Transcend are all cards that will not give you the performance SanDisk Extreme III will.

You've now tried two lower cost cards and should have seen you can't trust them.

When I retried, I had the same error. The difference is I have shot some still pcis and then recorded video. Is there such a thing that the card should exclusively be used for video recording. I am wondering that it may be my camera.

You shouldn't have to do that. It is not your camera although Canon has admitted some samples can be "brand finicky". When I had a T1i I shot both stills and video on the same SanDisk Extreme III card and never had a problem.

I now do the same thing on SanDisk Extreme IV 45Mbps (or faster) CF cards in the 7D and also have no problems.

Get the right card and you should have no problems.

If you get that buffer bar AT ALL you have an underperforming media card.

Look, you guys have spent close to a Grand or better on the camera. If you want the dependablility that goes with that price buy a decent card. If you're out on a project the last thing you need is to be "second guessing" your media.

Thank you Bruce for the info. Will get a sandisk

I just got this error on my brand new 60D, I just upgraded from the T2i and never had any problems with the same card, a little disconcerting! It was a Class 10 Patriot, 16 GB, but as Bruce is implying, you get what you pay for!

Worst part of it was, I was in a helicopter for the first time in my life!!!! I still got some amazing shots though....

Absolutely love the 60D otherwise!

New 60D and 3 new Patriot LX 32G Class 10 cards formatted in camera before use. Shot all day...10 hours...no problems at all.

Hey all, I figured out my problem, I was trying to snap a picture while shooting video, something I did frequently on the T2i, and video would normally resume after the shot. Problem is I've been shooting RAW photos recently, and I think it just couldn't handle that amount of data, switched it to JPEG and everything seems good again.

just out of curiosity...

1. why does Canon impose the 4GB limit, and could Canon remove this via a f/w update
2. how do you record long coverage then? use the HDMI out to a hard disk recorder like a Ki Pro?

Answer to your first question: there is no officially stated reason. Sources at Canon once told me that the 4GB clip length limit is there to prevent standard definition recordings from exceeding 30 minutes, thereby avoiding a significant tax penalty upon buyers in the European market. There's also the possibility that the 4GB clip length limit is self-imposed in order to protect sales of Canon's professional video camcorders series (XF, XH and XL H models). However, there are a number of other ways in which a D-SLR can't replace a pro video camera, so that reason isn't a very strong one.

Answer to your second question: you don't. The outgoing HDMI signal contains graphic overlay information which cannot be removed. Long-form recording of uninterrupted clips is more suitably achieved with a proper video camcorder, such as the afore-mentioned XF, XH and XL H series cameras.

Is either point changeable by firmware update? Unknown, but not at all likely to happen. Perhaps a third party will undertake it, but not the manufacturer. Hope this helps,
