Full Version: Why does a 7 megapixel camera...

Why does my 7 megapixel camera only allow a maximum video resolution of 640 x 480. It should at least be able to capture more data than that in a video. I mean, if it's a size problem, then I could buy more memory sticks. Does it have to do with encoding speed? Is there an actual cap to the data coming in from the lens?

(Note: I have a DVD camcorder for this purpose, but this question's always bugged me.

the video encoder's a separate device within the camera and it has limited capabilities, just like video capture cards in computers

Not just the encoder.
The sensor itself usually isn't able to deliver full resolution data at 30fps.

However, Casio just announced a camera that's supposed to offer 6mp at 60fps.

Reminds me of this camera I heard of that does HD video with sound at 15fps.

Because the sensor and image processor has a maximum bitrate that it can handle.

because also the memory card might have a speed limit wink.gif
