Hitachi springs Blu-ray camcorders on world

Two HD TV Blu-ray models go on sale in Japan this month

It's just two weeks after we caught whiff of a rumour that Hitachi would be releasing a Blu-ray camcorder in the autumn . But the Japanese company has announced that the portable high-definition technology is, in fact, ready now .

Moreover, for once in the world of cutting-edge gadgets, a company has surprised us by coming up with the goods for sale early. The world's first BD video camera will go on sale in Japan on 30 August. Overseas sales will start in October.

Hard drive option

In fact, there are two camcorders due out - the DZ-BD70 and DZ-BD7H. The former costs ¥160,000 (£666) and records only to 8cm Blu-ray discs, while the latter is ¥190,000 (£792) and also includes a 30GB hard drive.

The HDD version is more likely to succeed, as it can hold four hours of 1920 x 1080i high-definition video, whereas the 7.5GB single-layer BD-R/RE discs manage just a quarter of that. A lower resolution of 1440 x 1080i is available, which pushes those times up to eight hours and two hours respectively.

Internal editing

Software in the cameras allows for scene selection that approximates to a rough kind of editing and for dubbing the results to the hard drive in the case of the BD7H. However, dubbing is only 2x, so an hour of HD TV takes 30 minutes to copy.

Otherwise, the specs are pretty much what we already knew. Both models have a 5.3-megapixel sensor that delivers the equivalent of 2.07 megapixels for video and 4.32 megapixels for still shots. And both have a 10x optical zoom lens and 2.7-inch fold-out LCD monitor.

Both cameras also have similar battery expectancies, with the BD7H's 100 minutes just beating the 90 minutes of the BD70. The hard drive model is slightly heavier as well at 630g, compared to 575g.

Given the inevitably that other manufacturers will produce both Blu-ray and HD DVD camcorders soon, we can safely expect these two groundbreakers to be the first of many.
