    How long can I record at full 1080p on a 32GB card?

    Hi I jus got a new camcorder and I want to know how long I can record at the highest quality on differnt cards? I think 32GB cards are the way to go, but if anyone can let me know what size cards they are using and how long they can record at highest quality.

    please help.

    The thumbnail attached to this post: http://www.avforums.com/forums/12740442-post7.html

    should give you the whole range of times/card size.

    Personally, I think 32GB cards are too big. Get a fault, or lose a card, and you've potentially lost a lot of video! :)

    I still use 4GB, but for your higher rate recordings you might find 8 or 16GB cards more suitable.

    I agree, especially if you use class 6 (or above) cards.

    8gb & 16gb class 6 cards are pricey enough, I can't imagine what sort of money a class 6 32gb card would go for (are there any out yet?).
    I find class 6 cards guarantees stutter-free playback which class 2 absolutely does not and class 4 is a bit of a lottery.

    I'm disappointed about the 32gb cards, I'd love a 32gb micro SD card for my phone but they are very slow in coming & getting to a sane price.......which is a bit odd as 8gb & 16gb have pretty much got there now.

    you say class 4 is a bit of a lottery, does anyone else find this, i wouldnt consider buying a class 2, but thought the margin between class 4 and 6 would be quite small, or am i very wrong?

    Depends on the frame rate and bitrate 1080p25 and 1080P24 ( the bluray standard) use the roughly same amount as 1080i50 at the same bitrate. 1080P50 at 24mbps is a whole different ball game. Unless you are shooting scenes like sports with lots of rapid action you won't gain much from the nearly double storage not to mention the lack of PC's with sufficient processing capability to process 1920 x 1080 footage at 50 fps. Suggest anyone seduced by the magic 1080p50 tries 1920 x 1080 1080i50 and compares 1080p50. The resulution is the same, only rapid motion improves with the progressive option

    Kind of like the small margin between class 2 and class 4?

    Just kidding, all I'm saying is what my experience is, to be certain it works properly I use a class 6 card.
    I tried the PNY class 4 16gb cards and was very disappointed, ditto the regular Play class 4 cards.

    Class 2 is 2mb per second, class 4 is 4mb per second, class 6 is 6mb per second and so on in that fashion.

    A 32gb card is nice I've never seen one that's cheaper than two 16gb cards of the same speed and, as rogs said, that's an awful lot of eggs in one basket.

    Not quite right! :)

    Class 2 is 2MBytes per second, not 2Mbits --and so on.

    Important to make the distinction, because the camera specs are always in Mbits, and the card specs are in always in MBytes.
    As a MByte is 8 times biger than a Mbit, a class 2 card can deal with recording data rates up to 16Mb, a class 4 up to 32Mb, and so on.

    The highest data rate for the current range of AVCHD cameras is 28Mb, for the Panasonic SD700 series, so a class 4 card or above will cope with that.

    Handy info rogs.

    If only the cards (like all the other flash & hard drives etc) would actually live up to & perform as their stated spec suggests they ought to.

    My post is correct. It's annoying that some fields use bits and some use bytes. The relevant industries should get on the same page cos I'm sick of explaining it to customers. As soon as you use that sort of language some people just go into shock.
