SDHC Cards for HD video
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!

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. |

Transcend
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?

Transcend did not work either
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. |

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

I found the Silicon Image Class 10 16gb 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.
