Sony AVCHD CamcorderWhether you are upgrading from an analogue camcorder, updating your digital camcorder or choosing a camcorder for the first time, the decision over what to buy may seem a daunting one, with so many models, features and formats available.

 

The first question you should ask is...
"Standard or High Definition?"

Standard definition camcorders will record a picture at 720x576 (PAL standard for UK). Footage can be played back on all TVs, and can be burnt to normal DVDs and CDs.

High definition is the new emerging format, and HDV/AVCHD (High Definition Video) Camcorders generally record at 1920x1080. Footage can only be played back at full resolution on an HD ready TV, but most offer the ability to play back at standard definition on older TV sets. HD footage can be burnt to normal DVDs with lower quality, or at full resolution using a Blu-Ray burner.

The choice ultimately depends on your budget. SD camcorders can be bought for as little as £150 new, whereas HD camcorders start at about £450.

Even if you don't have the means to play back HD footage now, an HD camcorder does make a sensible future-proofed purchase, as you can record in HD, and scale your HD movies down to SD to burn to DVD for now, keeping your master footage for when HD disc creation becomes affordable.

It has also been noted that HD camcorder footage scaled down to SD looks superior to footage shot on an SD camcorder.

 

Recording Media - Quality or Convenience?

Probably the next choice to make is the type of media your camcorder will store footage on to. Here the decision comes down to a personal choice of both convenience of use and quality of the footage.

Traditionally, with standard definition camcorders, footage captured to tape media is better quality than footage captured to other media, such as DVD and hard drives. This is because with tape, the video doesn't need to be compressed as much to fit on the tape. This is also the case with high definition at the moment.

 

 

For more information on compression and the relationship between compression and editing, refer to my article on video compression.

The disadvantage of tape based footage is that you cannot easily locate and play back a clip you've recorded. With a hard disk, you can access a particular clip instantly.

It is slower to transfer your footage to your computer from tape based systems, and requires a 'Firewire' cable. Generally, this footage is captured in real time, so if you have 60 minutes of footage, it will take 60 minutes to transfer.

With hard disc camcorders, footage is transferred by USB, and the hard disc will appear on your computer just like any other external hard disk, therefore you can copy the files to your computer by dragging and dropping, which is much quicker.

With DVD camcorders, simply pop the disc from the camcorder into your PC and copy the files off to your PC.

So in summary, hard disc and DVD camcorders offer more convenience but lower video quality.

Table of formats:

Media
Format (SD)
Format (HD)
 MiniDV Tape
 DV-AVI HDV (MPEG2)
 DVD MPEG2 AVCHD (MPEG4)
 Hard Disk
 MPEG2 MPEG2 or AVCHD (MPEG4)

Because of the use of different compression technologies, some of the formats listed above are easier to edit with than others.

DV-AVI will be less taxing on your PC than the other formats. MPEG2 is the next in the list in terms of ease of use and compatibility, then finally MPEG4 (often referred to as AVCHD when used in Camcorders).

Software developers are now starting to implement the use of AVCHD in their software, but you will need a powerful PC and plenty of time for rendering in order to edit with it.

 

Other older camcorder formats still exist, but are mainly found in the secondhand market. Two notable formats are:

Digital8 - this is a Sony format which records DV-AVI onto Hi8 tapes. The video behaves exactly the same as MiniDV tapes, and is a useful format if you have lots of old Video8 and Hi8 tapes, as some of the models allow you to capture these old tapes into digital format straight to PC.

Micro MV - another Sony format which uses tapes which are even smaller than MiniDV tapes. The video is recorded as MPEG2. There is general support for this format in editing software, but it is best to check your software before purchasing a MicroMV camcorder.

Other considerations - Camcorder features

Lens - probably one of the most important factors in image quality, look for a camcorder with a quality lens. Brands such as Leica Dicomar and Carl Zeiss generally provide a good level of performance.

Low Light Filming - the ability to film in all lighting conditions is often the real test of a good consumer camcorder. Look for camcorders with larger CCDs. CCDs are the sensors which pick up light information and convert this into a digital picture. The larger the CCD, the more sensitive it will be to light, therefore the better it will perform in low light levels. 1/3 inch is the largest generally in consumer camcorders.

Manual Features - if you want to be more inventive with your film making, or you want to take control of your camcorder to give you the best quality picture at all times, consider the controls your camcorder will give you. All camcorder will run in 'Auto' mode - some do this better than others. There will always be times when manual control will give you a better shot, but these controls need to be easily accessed to be useful.

Viewfinder - increasingly, this feature is being lost from camcorders, but personally I'd never be without one. In bright sunlight, LCD screens can be difficult to use, as the brightness is often not sufficient to see enough detail. Also, LCDs will consume more battery power than viewfinders, so if you are filming long shoots with limited battery power, you'll be glad for a viewfinder.

Attachments - at some point you may wish to attach video lights and microphones to your camcorder. Consider if your camcorder has an accessory shoe, and what type it is. Many newer Sony camcorders come with a proprietary shoe which only accepts Sony accessories which will limit your choice. Many modern camcorders also come without a socket to plug in external microphones, so if you want to use one, you'll need to check this.

Still Photos - many camcorders feature a stills mode. Although all camcorders produce stills which are inferior to dedicated digital cameras, it's always handy to have both features in one device, even if you only use the photos in your home movies.

Final Word

Be clear about your requirements. Think about what you intend to do with your camcorder, and how much editing you'll likely be doing. Consider the features you will need to use, and the connections you may need.

Go to your local retail store and try a few out, see how they handle and how easy it is to get to the controls. Check the size, although smaller may seem better, if it is too small, you may find it difficult to hold it steady.

Also, ready impartial reviews on the web. I recommend CamcorderInfo, as they are impartial (although they bias towards camcorders which offer manual features), and they provide good test analysis on the site.

It's also worth scouting the web for sample footage from different cameras. If you can find the raw footage from the camera, this is better, as you can then also test it in your favourite software and see how easy it is to edit, and if your PC is up to the task.
