我也听到有人说DVCPRO比DV和DVCAM要好~
可是DVCPRO好象是松下公司开发的产品..
在品牌上不敌SONY,
同等专业级别的摄象机..松下的要比SONY的价格低1/3至1/2
我也是在左右徘徊着...
还请各位影视大虾继续发表自己的见解!

BETACAM------电视台 广播级的片子
BETACAM 有 模拟 和 数字 不同的种类
该范围设备较昂贵。性能指标极高 属百万关



DVCAM--------SONY的专利DV格式的专业扩展，大中小电教，电视台也用（近来）。新闻采访

*DVCPRO-----松下祸奖的专业格式。用的较广泛。电视台大多都有他身影，（DVCPRO50属更高。DVCPRO HD属更更高。为了高清晰电视而推出）


DVCAM和DVCPRO各有优点。都是DV的衍生格式 性价比较高 适合个人专业和地县电视台。属于10万关

虽然现在不少电视节目是用DVCAM或DVCPRO,甚至DV拍的, 但是按信号采样的标准来说都达不到广播级标准(broadcast standard), 而只是专业级的(industrial standard).

D1- Uncompressed Component Digital, 8 bit sampling, 4 audio channels, 16 bit @ 48 kHz

D2- Uncompressed Composite Digital, 8 bit sampling, 4 audio channels, 20 bit @ 48 kHz

D3- Uncompressed Composite Digital, 8 bit sampling, 4 audio channels, 16 bit @ 48 kHz

D5- Uncompressed Component Digital, 10 bit sampling, 4 audio channels, 20 bit @ 48 kHz

Mini-DV is a digital component format using high compression and providing two 16 bit audio channels with sampling options of either 44.1 kHz or 48 kHz.

DV-Cam is an 8 bit component digital format (4:2:0) using 5:1 data compression, it records audio in two 16 bit channels sampling at 48 kHz. Sony developed DV-Cam as a means of straddling high-end consumer digital video formats and 'true' professional formats such as D5 and DigiBeta.

DVC-Pro is the component digital format produced by Panasonic to serve the high end consumer and compact professional market. It has a lower compression ratio than Sony's DV-Cam and provides 4 audio channels with 16 bit sampling at 48 kHz. DVC-Pro uses a slightly different colour sampling format (4:1:1) than the standard Digital Video format (4:2:0). Panasonic suggests the main market for DVC-Pro is Electronic News Acquisition.

Betacam SX is a digital component tape format using 8 bit sampling with 4 audio channels, sampling at 16 bit, 48 kHz. Betacam SX uses a compression ratio of 9 to 1; higher than DigiBeta.

The most common digital video tape is Digital Betacam (DigiBeta); a component digital recording format, employing 10 bit video sampling with mild data compression. DigiBeta has four channels of 20 bit uncompressed digital audio, sampled at 48 kHz. Each channel can be independently edited.

DVCPRO 50 - The digital video tape format DVCPro50 was developed by Panasonic on the basis of DVCPro. It differs from other DV formats in that signal sampling is 4:2:2 and that the video data rate corresponds to 50 Mbits/s.
For enhanced signal sampling quality and higher data rate, the tape is played at double speed, thus reducing the running time per cassette by 50% in contrast to DVCPro. DVCPro50 in the PAL version records 24 tracks per frame, i.e. twice as many helical tracks as DVCPro. DVCPro50 provides four instead of two digital audio channels for sound recording. They enable a resolution of 16 bits/48 kHz.
