Vadohd: High definition Pocket Video Camcorders - Things to Take into account Prior to A Purchase

By Tim Caroll


Given that numerous High definition pocket video camcorders are light-weight, compact, plus some are even water resistant and can capture video under water these kinds of video cameras provide benefits above bulkier and heavier full size camcorders.

However, there are lots of additional factors to consider prior to making a purchase as you certainly do not want to incur post sales regret.

High definition Recording time

Generally you will want a minimum of 30 minutes of battery when recording and if feasible 60 minutes. This will depend on the kind of batteries and how much power the device uses. Thus be sure that you evaluate this specification.

Memory Storage

Your HD pocket video camcorder should enable you to store up to 120 minutes or 2 hours of HD video. Depending on the quality you capture this may be lowered. You should be able to capture at least 120 minutes at 720p if the cameras technology compresses it in an efficient manner. Solid state memory should be a standard of 8 GB and perhaps expandable around 32 GB should you deem this to be essential.

Sound and Microphone

Local playback sound isn't as critical as recording sound and although whenever you view your captured video from the recorder it may play from one speaker (mono) you will want to be certain that the audio taken is in stereo if you are planning to use the captured video for a quality exhibit. If sound isn't that critical to you then you can opt for a mono version, but consider that the experience will not be a genuine when viewing on your home pc HD monitor or HD TV.

Lens Zoom

Many don't realize the main difference in optical zoom and digital zoom. Optical zoom actually is a higher quality and will render a much better image when at the maximum focal length. You will spend more for a HD pocket camcorder that is capable of 2X or greater because of the complexity and quality of the glass in the lens.

Digital zoom makes the image as the processor interprets the image as increased focal length. Making this not really a true zoom function and also is not really usable at longer focal lengths, you should clearly focus on a pocket video camera that employs optical zoom rather than digital.

Frames Per Second

Some cameras may well enable you to get video at a frame rate of 24 fps (frames per second) which is a very efficient standard. This allows for high quality motion with little or no jitter in playback but with reduced file size. This may be considered a major factor in recording and battery life so maintain a sharp eye for the details of this specification.

30 frames per second is a standard that's very common and produces a slightly better quality transition in fast paced video capture. This is barely noticeable by the human eye and does trade the quality of this format for memory storage and battery life.

Viewing Screen Size

You may well be particular about the video that you capture and that it appears the way you want it without post processing. This is where possessing a larger viewing screen for playback will come into consideration, but again there is a downside for battery life and the bulkiness / size of the pocket camcorder. Remember to keep your focus that you are intending this to be as portable as you possibly can and you will logically be restricted on how large your viewing screen can be. Anywhere from at least 2 inches to 3 inches ought to be sufficient, however anything smaller than this will be hard to make out any details until you process the video on a bigger display screen.
