So recording time 1920x1080 (29min59sec) => 49 min. with a 16gb card!?

Edit: No, its a bit misleading in the manual. This here seems to be the important part: "The movie shooting will stop automatically if the file size reaches 4 gb"

Well, this seems to have lost something in the translation:

"or if the movie time reaches 29 min. 59 sec."

What a heartbreaker!

But i donīt really get it. Why isnīt it possible to capture 1920x1080 longer than 12 min. uninterrupted with a 16gb card?

Because they don't support file spanning. The cards are formatted in FAT32, which has a maximum file size of 4GB. That's about 12 minutes of HD video. So when the file size hits 4GB, it stops.

Some cameras support spanning, like the GH1 -- it creates multiple 4GB files and links them together. But some don't, like the Canons. So once you hit 4GB, it stops.

Is spanning something that a firmware upgrade might provide? And why the use of FAT32? Aren't there better choices?

Thx Barry. What about ntfs cards in the near future?

FAT32 is the universal standard of SD and CF cards. And it's universally supported by all major computer operating systems.

I would assume file spanning could be added with a firmware update.

Not unless Macs learn how to write to NTFS volumes.

Was this left out so Canon wouldn't face European tarrif problems as a camcorder? As I understand it, Panasonic cripples the GH1's recording time limits for PAL versions.

So the question remains why canon didnīt add file spanning from the get go? Correct me if iīm wrong but in their camcorder department they implement it, right?

That 29:59 number rings a bell with PAL GH1s. ;-)

Not only gh1s. This european tax law is totally outdated and should be repealed asap. But these ladies and gentlemen in brussels have more to do with curvy cucumbers: http://europa.eu/rapid/pressReleasesAction.do?reference=IP/08/1694 ... :-)
But weīre talking about the 12 min limit, arenīt we? Perhaps an overheating problem exists with the 2 digic 4 processors too?

I sure would not doubt the overheating thought but if you had stitching on the 7D, you could exceed 29:59 in a single recording (based on CF capacity) and violate the stoopid rule. Maybe some future firmware for the rest of the world. The thought that Canon would cripple to the lowest denominator is pretty sad.
