GY HM100 SDHC cards
on Jul 7, 2011 at 11:38:13 am

Hi,

I'm about to buy a GY HM100, so I'm also looking which SDHC cards to use. I know class 6 is the mininum, but I read there could be problems with higher classes, like class 10? Also, I found a website where they sell "class 1 HD" cards. Would these work?

Second; what bitrate should the cards have? I know the camera can go up to 35Mbit/s, which I assume, is when it records in 1080p. So the cards should also have a minimum of 35Mb/s?

If there are users here who can share there experience with this camera and these SDHC-cards, that would be great.

ps: just checking: the camera actually records in 720p and then upscales to 1080p, right?

Thanks,

Krisse

Hi Kristof,

the JVC GY HM100 takes both class 6 SDHC cards or class 10 SDHC cards. The ability to use class 10 cards was added with a firmware update but should be standard on all currently shipping models.

I've been using SanDisk class 6 cards for 1 1/2 years now and never had any issues. Others have used cheaper cards and have reported good results as well.

Class 1 cards obviously being neither Class 6 or 10 would not work.

The "class" states the transfer speed of a SDHC card so your question about the bit-rate is that it needs to meet class 6 or 10 spec which is 6 MB/s for class 6 (48Mbit/s) and 10MB/s (80Mbit/s) for class 10 cards. 35Mbit/s as the camera shoots would equal 4.375MB/s)

See http://en.wikipedia.org/wiki/Secure_Digital#Speed_Class_Rating for more info.

And yes, the CCD's in the HM100 are 720p resolution that get scaled up within the camera (which does a really good job at it too!)

Hope that helps.

André

Thanks for the answer.

I do have a bit of a dillema right now: since Sandisk is quite expensive I want to go with Transcend cards (half the price, good rep). But I've read about incompatibility problems of those class 10 cards, that aren't fixed with the firmware upgrade. Should I go with the class 6 the, just to be sure?

Thanks!

I know that Philip Bloom used Transcend class 6 cards in his review ( ) and personally I have only been using class 6 cards and there is no problem with that. Class 10 is supported but not needed so by all means give the Transcend class 6 a shot.
