Two Years Ago

I just missed my anniversary.

Two years (and two days) ago, I started this blog!

Thanks to all of you who read it regularly.

Three Key Camera Subsystems

When comparing different video cameras, I like to think in terms of three subsystems that each massively impact the quality of the image that results.

• the lens(es)
• the sensor(s)
• the data encoding

Note that there are lots of other features that will distinguish one camera from another, but the three above are the key ones that directly affect the image.

The JVC GY-HD101E I just bought has the following:

• a prosumer-grade Fujinon 5.5mm-88mm zoom lens but interchangeable with other 1/3" bayonet lenses (1/2" or 2/3" with suitable adapter)
• 3x 1280x720 1/3" CCD sensors
• 720p (HD1) HDV (MPEG2 19.7Mbps, 4:2:0 chroma sampling)

I'll say more about what each of these means in subsequent posts. It's a pretty fascinating area of technology.
