Varicam’s horizontal resolution
I’m confused. I asked a Panasonic rep what the resolution of the Varicam was and he told me it was 850 horizontal lines. When I received my copy of the printed Varicam booklet (SP-HDC27HP1) it says it’s 700 lines.
Which is it?

Hi,
Horizontal resolution at the center of the picture for a HDC27 VariCam is 700 Television Lines which is the spec. This is perfectly acceptable for HD acquisition. But horizontal and veritcal resolution is not the entire story. One must really look at the picture quality which is hard to determine as each person percieves the quality differently. As I have said for many years, “don’t count the prixels, count on the pictures”.
Research shows that resolution is much more that TVL and Pixel count. Contrast, color acquity, and resolving power of the imagers and A/D conversion and compression play a very import part in the overall picture quality.
So just looking at numbers does not tell the entire story of image quality. The idea that a higher number is always better is just not true. There are many factors to consider. But it really boils down to these two ideals: Does it conform to my creative needs, and is it economicaly viable? In other words, can I make the programs I want to make at an affordable price?
Only you can decide. Afterall, these are only tools.I hope this helps to put this conversation into perspective.
Thanks,

Whatever the camera display is one matter but what actual gets recorded to tape is more important.
Depending on what your applications are the spacial resolution from the camera and recording medium will have a major impact on your needs.
You can’t have it cheap, quick and ultra high resolution all in the same package at this time.
