JVC Everio GZ-HD620

Colour (10.57)

JVC camcorders often have the best colour accuracy amongst consumer models, and the GZ-HD620 follows this trend. In bright light, the camcorder managed a colour error of just 3.31 and a saturation level of 81.78%, both of which are excellent numbers. The HD620 even managed to render better colours than it's big sister the JVC GZ-HM1. (More on how we test colour.)

Colour Accuracy Performance
Colour Test Chart (above), Colour Error Map (right)
The JVC GZ-HD620 produced a colour error of 3.31 saturation level of 81.78% in our bright light colour testing. (The map on the right is a diagram of the colour error. The length and direction of each line indicates how the camcorder processed each particular colour.)

The Colour Error Map shown above tells us that the GZ-HD620 did a very good job rendering blue and red tones accurately, but the camcorder had some trouble with greens and yellows. Overall, we like the way the camcorder captured colours very much, and we seem to say that about most camcorders from JVC. Unfortunately, the GZ-HD620 does not have any colour controls or colour modes, so the only sample image we can show you is from our auto mode footage (below).

All of the camcorders we compared the GZ-HD620 to (see the images below) produced pleasing colours in our bright light test. They also all had a different way of rendering certain colours. Since colour quality depends more on personal preference than anything else, we urge you to check out the images below and the close-up comparisons that follow to get a better idea of how each camcorder renders colours in bright light.

Noise (10.15)

The GZ-HD620 averaged 0.575% noise in our bright light test, and we usually consider any noise levels around 0.5% as very good. The Panasonic HDC-HS60 measured the highest noise, but still under 1%. All camcorders we compared the HD620 to did well in this test. (More on how we test noise.)

Usually, it is difficult to see any noise in bright light images (this changes in low light), but the crops shown above provide us with another use: determining sharpness and detail. The GZ-HD620 produced a bold image, but it wasn't quite as sharp as what we saw from the Canon HF M31 or the JVC GZ-HM1.
