Digital Video Cameras: Not Your Father's Super-8
Camcorders have been around for years, but today's sleek technologically advanced digital video cameras are huge improvements over the bulky VHS cameras of the past.
...Look at a few digital video camera reviews and it's easy to get confused, so let's examine the key factors to review when comparing digital camcorders.
High resolution video and CD quality sound are hallmarks. And even with features like image stabilization, full-color viewing screens and high powered zooms, many of these cameras weigh in at less than a pound.
Digital video camera applications are amazingly diversified. Preserving milestones and memories like wedding, birthday and vacation videos are just a few. Digital camera technology and super miniaturization allow hidden digital cameras to record activity at a business or home. It's said that many of us are recorded on a digital surveillance camera several times a day in our normal activities.
How to Compare Digital Video Cameras
Look at a few digital video camera reviews and it's easy to get confused, so let's examine the key factors to review when comparing digital camcorders.
Camera Format
Almost all digital video formats deliver 500 plus lines of resolution and CD quality audio. This is about twice the resolution of VHS with vastly superior sound. The following summarizes digital video camera formats:
- MiniDV video cameras are compact, have broad software & hardware support, and can record several hours of video. They are the most popular video cameras.
- MicroMV are ultra compact video cameras using the smallest video cassettes. These cameras record in high quality MPEG-2 format. Software/hardware compatibility is limited and cassettes are more expensive.
- Digital8 video cameras are lower priced and also play older analog 8mm and Hi8 video cassettes. While slightly larger than MiniDV camcorders, they have wide compatibility with editing software and hardware devices. Some provide analog to digital conversion features for older videos.
- Mini-DVD camcorders record directly to mini DVD-R or DVD-RAM discs. DVD-Rs can be played on most DVD players, while DVD-RAM discs require a DVD-RAM drive. Mini discs provide easy storage, but video recording time and editing capability are limited.
- Micro-Drive and Memory Card video cameras offer ultra compact designs and like Mini-DVD cameras, easy search/access. The unique features of these cameras make them better suited to gadget-loving techies.
Image Sensor and Light Sensitivity
Digital camcorders use CCD (Charged Coupled Device) sensors to interpret light and color. In general a larger CCD delivers more pixels and better quality video. High-end video cameras feature 3 CCD's, each dedicated to a single color for better resolution. The CCD should be at least 1/6 inch, delivering 290,000 pixels or more. 1/4 to 1/3 inch with 690,000 plus pixels is even better.
Light sensitivity, or illumination ratings should be no higher than 7 lux. For low light videos, 2 lux or less is preferred. To capture digital still photos from your video, look for a still resolution rating of 1-2 megapixels.
Optical vs. Digital Zoom
Look for at least 10X to 20X optical zoom. Digital zoom is practically worthless because instead of zooming in on the subject, it crops the image, severely reducing pixels and degrading resolution.
Exposure and Focus Controls
These controls are automatic on almost all video cameras. But manual overrides provide better video in situations like focusing on a subject in front of a distant background or adjusting for unique lighting conditions.
Viewfinder and LCD Screen
The viewfinder may be black & white or color, largely a personal choice. The LCD viewing screen should be 2.5" or larger. If possible compare screens outside in sunny conditions as some will wash out so badly they're effectively useless.
Other Cool Features
Some will add significantly to the camera's cost, so carefully evaluate and decide which ones you will actually use (unless of course you simply must have the coolest video camera available).
- Progressive scan rather than interlaced
- 16:9 widescreen mode
- Wireless (Bluetooth) and remote control
- High definition capability
- Webcam, email and cell phone functions
- Fade and other digital effects
There are many more options, but match these key features to your needs when doing your digital video camera review and you'll ensure your video camera choice provides the flexibility and enjoyment you want.
