Key Considerations in Choosing Camcorders


Prospective camcorder buyers are faced with a choice of four types of camcorder recording media: hard disk, flash memory, MiniDV/HDV tapes, or mini-DVD. Here are the pros and cons of all four formats.

  • Hybrids—In the case of camcorders, a hybrid is any camera that allows you to record video on two types of media. The first set of hybrids, produced by Hitachi in late 2006, combined both hard-disk and mini-DVD media. Now, however, this term is used almost exclusively with camcorders that use flash memory and either hard disk or mini-DVD. We'll go into more detail as to why flash memory hybrids are a good idea when we examine each recording medium.

    Most of the new hard-disk and mini-DVD models released this year are able to record video to removable flash memory, typically either SD or Memory Stick cards. However older models still on sale, as well as many second-hand cameras, are only able to store still images not video on their removable flash memory.

  • Hard Disk—The beauty of hard-disk camcorders, especially in this age of high-definition video is that nothing else offers the same value per gigabyte. Most of the current hard drive models available are hybrid units that allow you to record to removable media — so if you run out of space during a year-long round-the-world trip, you can top up storage capacity by gorging yourself on SD or Memory Stick cards.

    Hard disk capacities on standard-definition cameras range between 30 and 60 gigabytes — at maximum quality (about 9Mbps) — is good for around 430 and 860 minutes respectively. Meanwhile high-def hard-disk cameras usually boast between 40 and 120 gigabytes. This should be good for about 290 and 880 minutes respectively at 1920x1080i 16Mbps. Some of JVC's latest high-definition cameras can record at 26Mbps, meaning that you can only cram in 600 minutes of top quality footage onto the GZ-HD6's 120GB disk.

    Whether you choose standard-def or high-def, a 30GB or a 120GB model, a hard-disk camcorder will provide more than enough storage space for most situations. Indeed you're far more likely to run out of battery juice at an inopportune time, rather than be caught short of space. The great fear with all portable hard-disk devices is that the disk will get scratched by sudden movements and drops, but all modern camera hard drives have enough protection, buffering and smarts to withstand all but the most severe of falls.

    Most high-end camcorders nowadays are hard drive units, so if you want features like a hotshoe, headphone and microphone jacks, and a viewfinder, you'll have to stump up the big bickies.

  • Flash Memory—We've spoken at length already about hybrid cameras with supplementary flash memory, both removable and built-in. There is, however, a gaggle of cameras with only flash memory on-board. Mini-DVD, tape and hard drives are all fairly large immoveable objects around which a camera must be designed. Flash memory, on the other hand, is compact and frees the designers' hands somewhat. This means that not only are flash-only cameras smaller than their brethren, but they can be shaped differently too — witness the upright Sony HDR-TG1 and the discontinued Canon HV10.

    Some may find the petite dimensions to their advantage — space-deprived travellers, for instance — but there are a few downsides. Generally we've found that these smaller, lighter cameras are harder to hand hold, especially for extended durations. And despite the fact that flash memory prices are falling as fast as oil is rising, flash memory is nowhere near as cost effective as hard-disk. This isn't much of an issue for standard-def cameras, but can be problematic for high-def models — a 4GB SD card or Memory Stick holds a smidgen less than half-an-hour's worth of top quality footage.

    Keep in mind too that not all memory cards are created equal. To keep up with data being saved to it, SD/SDHC cards used with camcorders should be rated 40x (6MBps) or above.


  • Mini-DVD—As the name suggests, these camcorders record onto a small DVD disc — 8cm versus a regular DVD's 12cm diameter. The great — and some would say, the only — advantage of DVD camcorders is the ability to burn a copy of your masterpiece straight away. However, while the reduced disc size ensures that these cameras aren't built only for giants, it greatly reduces storage capacity. A full-sized single-sided, single-layer DVD holds 4.7GB, whereas a similar mini-DVD only holds 1.4GB. That means you'll only be able to cram in a paltry 20 minutes of standard-def footage, or 10 minutes of high-def, at high quality.

    Since the advent of affordable hard-disk camcorders we've been loathe to recommend mini-DVD models. The tide may be turning somewhat though with Sony's new DVD camcorders being hybrid models that can record video to flash memory — some models even have built-in flash memory. Recording to flash memory has the advantage of allowing simple editing functions, like scene deletion, that are usually denied to DVD camcorder users. This means that users can finally choose the scenes to burn to disc and can make multiple copies of Uncle Jack's 90th to hand around.
