Sd Card Recorders

[kclives]

I am thinking of getting a £100 SD card video recorder, please could someone clarify:
A) How many mins of vid i could get on a 1gb sd card at 640*480 at 30fps
B) Are these cams any good
C) If anyone has 640*480 30fps clips could you post so i can see quality

thanxx

What codec does it use? Xvid, MPEG, MOV? Do you know the Make, Model of the recorder/camera? Need more info.

Hi kclives,

You might want to check the resolution (640 x 480) and framerate (30fps) - these appear to be NTSC figures, whereas the UK is PAL.

Nowadays, most standalone players and TVs support NTSC but I'd look into this first if it were me.

Are you refering to something other than the digital cameras now on the market that have upgraded their video from 320x240 to 640x480?

As a test, I plugged into my slightly older Kodak 3.1Mp a 1GB SD Sandisk.
I recorded approximately 20 minutes of video (320x240) AND FOUND THAT IT TOOK AROUND 1/4 TO 1/3 OF THE CARD'S MEMORY SPACE.

So, I would think that doubling the resolution would at least double the consumption.

The format of video ala digital cameras actually vary somewhat. I don't have those particulars myself.

SD = ASF

Interesting stuff, you can use ASFtools to work with those files.

Ok i gonna buy either the Nisis DV6 or H10DV6 or DVM1 or GeniusGshot

All of these record to an SD card at a max of 640*480*30fps

From a ad for the Nisis camera:

"Over 60 minutes of Digital Video on a standard 256 MB SD Card" (Their site says 512 MB maximum size card, though) And they don't make it completely clear if the 60 minutes is at 640 X 480 resolution or the lower 320 X 240.) If it were able to use a 1GB card, that would be 4 hours.

"Digital Video MPEG-4 / XVID Camcorder" Apparently it can save with the Xvid codec. That's good.

I would do a net search for some reviews of those cameras. The manufactures information may not exactly answer the questions you are asking. They tend to pass over any weak points of their products.
