Please explain in detail the difference between ordinary HDV digital cameras and broadcast cameras.

1。 Ordinary HDV is shot in 720-line progressive scanning mode or 1080-line interlaced scanning mode. Its frame rate should be 30 frames per second, and the picture is 16:9.

2。 Broadcast-level cameras should have 625 scanning lines and 25 frames per second, which can meet the broadcasting requirements of TV stations. The picture can be 4: 3 or 16:9. The general model is DVCPRO DVW.

3。 The camera for digital movies is a broadcast-level machine with the picture of 1920* 1080, which belongs to a large high-definition machine. The picture of 16:9 is generally used to shoot digital movies. The format of taking a frame in the later period of 25P is generally HDW-750 HDW-900R. The difference between them is that digital movies are high-definition machines and TV plays are standard-definition machines, but in recent years, TV plays are also filmed in high definition.

In addition, although the number of scanning lines of HDV can reach broadcast level, the setting of CCD-sized color saturation machine is much worse than that of broadcast level machine, which leads to that HDV can shoot DV in high-definition format, and the price is 20,000-30,000. Broadcast class 10w-20w or so, and high-definition broadcast class 50 W-80 W or so.
