I have tried formatting my SD cards but still having the same problem of video recording terminating at 10 secs...:cry:
So must really get a Class 10? The Class 6 SD is not cheap too right?

Pls read Pg 2, post #29 of this thread.
I dun get it. U guys knew the min for smooth video is class 6 but went ahead & bot a class 4 HOPING it'll work fine. Its like hoping a 1000cc car can go up Genting w/o problems, what r the chances huh?
Btw, i got another 2 more Sandisk 16GB Extreme class 6 for $83 incl GST at AP 2 weeks ago. Comparing ~$65 for Ultra class 4 vs Extreme $83 for class 6, not that big gap le. Again i dun understand, people can afford a $1400 60D body but can't afford to pay extra $18 more for a class 6 SD card.I'm speechless.....
It is not a matter about buying.....most people agree that a Class 4 SD card can record HD video. So it is the myth with the SD cards, why some people can shoot and some cannot?
Anyway my latest discover with my SD cards:
I have managed to record video with my old SD cards...
SanDisk Ultra II, 1 GB (No class indication)
Kingston Class 6 8GB
The new SD cards that are not working:
SanDisk Standard Class 4, Blue card
SanDisk Ultra Class 4, 16GB
Any difference among the cards?
Seriously no idea dude... maybe u are unlucky got a lousy batch of the ultra card... My Lexar card is given free when bought together with 60D and no issues with recording full HD...
1. Class rating guarantees a minimum data size/sec performance. Class 2 means minimum 2MB/sec, so Class 4 is >= 4MB/sec, Class 6 is >=6MB/sec....etc, etc (http://www.funtechtalk.com/sdhc-cards-what-does-the-class-mean-2-4-6/). But note this is just the minimum. Doesn't mean that a card can't perform faster than its rating. As shown in this detailed review, some class 4 cards can do better than some class 6 cards.
2. According to the 60D camera specs in the manual, full HD data filesize is approximately 330MB per minute of video, which works out to be about 5.5MB/sec. There might some momentary increases during recording, but it shouldn't exceed too much for too long, and since there is also a memory buffer in the camera, a card that can sustain at least 6MB/sec will be able to handle the full HD recording task. That's why at least a class 6 card (i.e. >=6MB/sec) is recommended in 60D's case.
3. Are there cards labeled class 6 but can't do 6MB/sec? In my experience yes, because I've bought one from eBay rated at class 4 when it is actually class 2. How did I know? Fortunately the camcorder I used it on has the ability to display the speed class of the card. So I believe there are fakes floating around in the market. Also, I've read somewhere (can't remember exact url) that some manufacturer shamelessly publishes class ratings based only on read speeds but not write speeds. This certainly adds to the confusion that most consumer already have about class rating.
Hope the above helps those struggling to understand this issue. One thing I'm not sure is, since the Lexar PII card can do at least 9MB/sec, why don't they label it class 6? (or for that matter class 9!). Wouldn't that help them sell more, or even justify a higher pricing? Keen to hear from any experts around about this....
Hehe... got ask this question before but nobody reply....
How about Kingston class 10? It is cheaper than ultra... I assume it is able to record HD smoothly...
I dun think its min speed rating on the classes. Its more like a theoretical no. (peak burst at most) very much like ur SATA2 interface. Rated 3Gb/s but when u do a test, its barely 480Mb/s (even peak burst). Constant data throughput is even lower.
Also can't compare with different brands/models & P&S cams, cos they have different compression settings resulting different data. Although 60D rated 5.5MB/s, but i highly doubted it. From the looks its more like 3MB/s quality to me. The Singtel MIO & Starhub HD even worse, much lower than that & much higher compression.
Juz get a class 6 card & no more worries. Shoot at ease la, why risk? Not like class 6 is super duper expensive le.
Class 6 is faster than class 4 right? Class 4 is borderline case but class 6 is above that threshold. Class 10 too ex so i dun recommend lor, something more "down to earth" pricing & gets the job done. U get what i mean?
So far class 6 can handle all DSLR HD recordings. Only exception ATM is the GH1 hack, that hack brings the data higher than normal, Class 10 is needed.
