View Full Version : 60p overcranked slow-motion Vs. Optical Flow

I have been trying to decide between the HD200 and the HD110. The biggest selling points for me are the ability to shoot 60p and convert to 24p for the slow-motion feel. But if I can achieve this with optical flow,.......is it really necessary. Anybody have experience with quality differences??

Aside from that,......is the HD200/250 really worth the price jump?

Thanks

Hi Ian,

There are several feature and video quality advantages to stepping up to the 200 or 250. Please see the info below from our web pages:

200 Series Picture Improvement Technology
JVC's GY-HD200U and GY-HD250U offer substantially better horizontal resolution and signal-to-noise thanks to advanced image processing technology developed by JVC.

14-bit A/D converter
To improve both the S/N ratio and the horizontal resolution, a new 14-bit A/D converter was specially developed by JVC to prevent signal deterioration and to generate a fourfold increase in radations.

Wideband front end processing
The ProHD camcorder uses a wideband analog front end to process its CCD sampling via the 14-bit A/D converter. This further improves the S/N ratio and horizontal resolution by optimizing the CCD drive circuitry. The new LVDS (Low Voltage Differential Signal) interface minimizes any other possible signal degradation and so contributes to the improved S/N ratio.

Newly-developed pixel converter
To enable 720p/60 recording, a new super encoder and a new pixel converter were developed, incorporating an adaptive filter which optimizes the scalar performance of cross-converted signals, including 1080i. The resultant effects are increased resolution and reduced aliasing. Objects thus have much more natural looking edges and images are therefore extremely lifelike in appearance.
