How do digital VD machines look at cost performance?

How to compare the parameters of 1 DV machine to see which is more cost-effective?

Answer:

First, the choice of DV depends on the brand first, the eldest Panasonic, the second Sony, the third Canon, the fourth JVC, the fifth Samsung, and the rest of the miscellaneous brands need not be considered.

Second, look at the pixels, of course, the higher the better.

Third, look at the size of the hard disk to see if it supports direct recording of movies on DVD.

Others can be ignored.

2. Is photosensitive CCD or CMOS better?

In principle, CCD is superior to CMOS, but CCD has high cost and good imaging quality.

The advantages of CMOS are used by high-end digital cameras, and the main imaging quality of CMOS is poor.

, low cost, is currently being resisted by cameras or mobile phones. This statement was made a few years ago. At present, CMOS has surpassed CCD, and Canon EOS series all adopt high-grade CMOS, which has the advantages of true color reproduction and fast photo processing, and is adopted by professional cameras. Whether CCD is good or CMOS is good depends on the grade. At present, the dv produced by large factories can completely ignore the use of CCD or CMOS processors.

3. Is it better to use DV with high pixel of photoreceptor or digital zoom factor? Because I noticed that some pixels are high, but the zoom factor is low, while others are the opposite, with low pixels but high zoom factor. Who can explain how it is clearer?

In principle, the higher the better, the bigger the better.

It depends on your needs. The higher the better, the bigger the better.

I'm telling you, you are not a photographer. It's good to have enough.

4. Which is better, battery or battery?

Both have their advantages and disadvantages.

The battery is easy to use and can be replaced if it is broken, and the price is affordable.

Lithium battery is ready to use, but its life is not long, usually about two years.

The battery is broken. It's expensive to buy a new one. Digital things are updated quickly, and buying a lithium battery is still a problem.

Choose the same cost performance, the same performance, the same configuration, and give priority to the brand.

Supplement: Don't excessively pursue high configuration and high pixels, which will only make you spend more money and the things you buy will be useless. In fact, the general configuration is enough.
