Does the megapixel of a digital camera affect the video quality it can take?

Question by Tom M: Does the megapixel of a digital camera affect the video quality it can take?
My buddy says that the higher the megapixel a digital camera has, the better quality video it takes. I was not sure how true that statement was. Can anybody clear this up for me?

    There are many factors, mega-pixel is only one of them. Lens quality is another. It is possible for an 8 mega-pixel camera with an excellent quality lens to take better pictures than a 10 megapixel with a fair quality lens, for example. Before I bought a camera I would go to the library and read Consumer Reports, or pay for the on-line version at:

    http://www.consumerreports.org

    I have found that their ratings and recommendations of digital cameras are excellent.

    Good luck!

    in a way the higher the megapixel the camera is the clearer the image will be when you record.

    Basically the higher the megapixels, the better, sharper, and clearer your pictures will be if you go blow then up and get then developed. But to be honest, I think the megapixel rating stuff is a little overrated. woohoo for you if you have a 10 megapixel camers. My 1.3 megapixel cam takes great pictures when i get then developed. Thank you.

    That is not true. Your friend is not correct (for a general case). The mega-pixel is a factor only when you are concerned with still pictures. For video, there are different things such as the VIDEO resolution that is offered on the camera. The reason being, making a video is like taking 30 pictures a second and if you are recording sound too, it will take a loooot of memory much faster than images would. So, in order to make themselves look good, these companies make the video resolution much smaller, mainly because your card won’t be big enough to hold the video. If you have a 10MP camera, the highest video resolution possible would be like less than 1MP.

    Also a note of caution, the design of the lens is also a huge factor. Lens technology used in video cameras and still photography cameras is quite different and one is not good for another. That is why, if you want to make videos, get a video camera. If you want to take pictures, get a photography camera. Don’t think that your still photography camera will replace your video camera or that your video camera will replace your imaging camera. YOU WILL HATE IT.

    ya. it does a lil.. All camera’s recorde at the same reselotion. But if your camera is like a 6mp then you can pretty much make it full screen and watch it. But if you take a video of a 6mp and video of a 3mp.. YOu won’t find any big diffrence. But the casio Exilim on the other hand is differnt. Their the first camera to make their video resolution so close to a video you’d take with your camcorder. Don’t believe me? Check out the casion site yourself.

    No, I don’t really think so…it really depends on the camera used.
    Photo quality and ‘video’ quality is determined by the lens, sensor and processor used in the camera…so, you could actually have a camera with only 6MP which shoots better looking ‘video’ than a camera with higher megapixels.
    Video which is taken by a digital camera must be compressed due to it’s incredibly large size (best resolution movies can eat up about 1GB in just 8 minutes).
    Some manufacturers compress their ‘video’ much higher than others. The more it’s compressed the worse it can look (called compression artefacts).
    Probably the best ‘video’ resolution you can on a digital camera, is 640×480 at 30fps, which is ok played back on a monitor or TV. Some cameras can even record 1024×768 or in widescreen, however they will only have a frame rate of about 15 seconds…which means they will be jumpy.

    So, it all can depend on the brand of camera used, that can determine the quality of the ‘video’…and how the ‘video’ is recorded and compressed (most ‘video’ is recorded in the Avi or Mpeg format…Mpeg 4 is better than Mpeg 1).
    I have found that Canon has some of the best quality ‘video’ available on their digital cameras. Their video is not highly compressed, so it can look very good.

    But, don’t ever expect ‘video’ from a digital camera to ever be as good as a dedicated video/HDD camera.
    It’s a good little feature to have on a digital camera, fun and very handy at times (even good enough to produce YouTubemovies).

    No. See this link:

    http://www.dpreview.com/reviews/compare_post.asp?method=sidebyside&cameras=canon_a620%2Ccanon_a630%2Ccanon_a640&show=all

    Note that these are pretty much the same camera changed through evolution. They are 7 MP, 8 MP and 10 MP.

    Scroll down to see the “Movie Clips” specification. You will see that all three are absolutely identical.

    I did a similar comparison of a bunch of 7 MP cameras and found that they were all different, but none were over 640×480. There were only two 8 MP cameras that could go any larger and about half of the 10 MP cameras could go larger, but about half were limited to 640×480.

    The key thing, then, is to check the specs on the cameras YOU are comparing. Just knowing the pixel count is not an accurate guide.

    No its totally different.

    To keep it simple.

    Digital still cameras were designed to take still pictures, or still photography. Here they use the term Megapixels for the capability(number of sensor elements) of the camera to capture data of an image taken. The bigger or higher megapixels, the better or higher amount of data recorded.

    This doesn’t mean that the image is good right away. It just means that your digital still camera is capable of capturing such and such amount of data. There are several factors that contribute to a “good quality image”; lens is a big factor.

    Now having said that, the manufacturers of these still cameras decided to thrown in a little feature called video recording with optional audio for some.

    You have to remember that the first digital cameras, Sony Mavica were based on video technology. They were actually considered digital video cameras that shot still images and stored them in floppy disks.

    Now even though having internal organs capable of recording videos, our digital still cameras were designed to record still images.

    The factors that would ensure quality video images are the sizes and the number of CCD’s (Charged Coupled Device usually 3, thus the term 3CCD) and The bigger the CCD that is used, the better the color and image quality of the video. The bigger the hole in your wallet would be. The lens is also a big factor. For digital, its also compression; avi., mov. and now MPeg4.

    With respect to the manufacturers of our digital cameras, the quality of the video that they capture is quite good. Many of the point and shoots have better video quality than our old video 8 or hi-8 cameras.

    a 1GB SD card will hold about 14 mins of TV quality video.

    I hope this helps Bud.
