Micro SD card class question please

[BigonaBianchi]

I want to get a 32gig micro sd card for my new headcam. There are a range of them online but I dont understand what the class thing is on cards like this:

I just want to record my rides in a headcam...which 'class' card do i need?

generally you want to get the fastest class you can, as its do with the read/write speed of the card.

What resolution videos will you be taking at do you know what format they are stored in?

I was just about to post the exact same question! Looks like the Class 10 card is the way forward.

If you think of video as being like a slideshow, every frame the recorder saves every pixel (for simplicity of the example ), so the more pixels or the higher the framerate the faster it needs to save data to the card. IIRC you need class 10 for a full HD 1080p video camera and a class 4 for the chewing gum style 640*480 30fps cameras. If you use a card that's a little too slow I think you usually just get sporadic lower framerates so it looks jerky.

It has been suggested that the higher class cards are optimized for large files so class 10 for cameras but not all devices
