I want to ask a question about cameras.
now there are hi8 digital8 minidv and hdv cameras.
among these hdv is giving the best quality.
I don't exactly know but I think that minidv and hdv compresses the video with dv encoder before putting in to tape. And video quality is decreasing(but not very much) .
do professionals use the same cameras (minidv and hdv) or they use cameras which don't encode the video (record as uncompressed.avi)?
and are there any cameras like these(which don't encode)?

DV format is widely used for news, reality type shows, cable network programs and corporate video. SD pro variations are DVCAM and DVCPro. The recording system is nearly identical to consumer MiniDV. The camera sections are much better.

Next step up for SD is Digital Betacam and DVCPro-50 which are compressed 2-3X vs 5x for DV. These are normally used for program production. Uncompressed recording is rarely done in the field. Inside the studio most signals are decompressed (SDI) to video servers for editing convenience.

HDV is intended mostly for consumer and prosumer (e.g. weddings, corporate video, small TV station news, etc.)

Workhorse broadcast HD formats are IMX-HD (Sony XDCAM), DVCPro-HD and HDCAM. All are compressed (3x to 8x).

HD movies and TV series are recorded to HDCAM-SR or DVCProHD (Varicam). Film is still dominent but shooting in HD format is gaining share.

All these recording formats are compressed. Higher end models use 10 or 12 bit processing. At the high end of TV and movie special effects, short sequences of uncompressed HD may be recorded directly to video servers for certain effects processes.

Studio and field event cameras usually don't compress. They output uncompressed serial digital (SDI) to the video switcher. High end HD movie cameras are capable of full 10 bit 4:4:4 RGB 1080p output over serial digital connections.
