Res difference between HV20 and XH A1 Cameras
on Nov 5, 2007 at 1:22:25 am

Hi

What is the difference between HV20 1920 x 1080 High def and the XH A1 3 1/3" Native 16:9 CCDs 1440 x 1080? So in other words why the resolution number difference between these two.

Hope you will understand what I am saying

The XHA1 will give you a better picture, hands down.

You can't really compare the sensors of these two cameras because they work in different ways. The HV20 captures all of the colors with a single integrated sensor. The XHA1 has three different sensors, each roughly the same size as the HV20's, each dedicated to a different color. The three-sensor system gives better results.

In addition, the XHA1 has a better lens, further improving picture quality.

In the end, both cameras write the same HDV format at 1440x1080.

[Jeffrey B.] "The XHA1 will give you a better picture, hands down."

Could you back that up with some resource(s) please. A link perhaps.

While what you say MIGHT in theory be true, I have read otherwise. The HV20 uses a CMOS sensor where the XHA1 uses CCD's. I believe someone reported in the HDV forum stating they could see no difference between XLH1 and HV20 footage (in good lighting)suggesting excellent image quality indeed. I have the HV20 and would like to hear of some side by side comparisons.

Well both the CMOS sensors and the CDDs in all the Canon line are quite excellent, really... and give great results. I don't believe you are going to see any appreciable image quality difference that you can attribute to the sensors.

A lot of the "picture quality" difference is going to come down to the glass. The higher-end the camera in that line, the better the lens. The little HV20 has a pretty good lens, considering it's price... but you have to realize that with the HV20 the entire camera costs far less then the lens alone just two clicks up in the Canon chain, the XLH1... and the XHA1 will fall some where in between.

You can only have so much expectations from the built-in lens on a sub-$1000 palmcorder camera. But, that being said, the HV20 is still pretty darn amazing for the price (ahh... if only it had a full manual mode).

FYI, following is the official workflow from Apple on how to ingest and work with HDV 24P footage captured from an HV20 camcorder into Final Cut Pro 6:
