In answer to a question posed by johnq regarding the composite video output from the JVC Professional GY-DV5000 camcorder, it is post the DV sampling and compression process. This is also true of the Y/C output.
A comment has been made regarding the quality of these signals and while the composite output has gone through the digitizing process it is certainly good enough for live switching. It is worth remebering that NTSC video is arguably the worst video signal on the planet!
The composite and Y/C outputs are provided on the GY-DV5000 for field monitoring and making VHS or S-VHS dailies "on the fly".
As to the reference about Beta, the composite video output from a Beta deck is likely E-to E through the recording electronics as well (after the CTDM process) and would probably be the same quality as that of the GY-DV5000's output. While the original signal is different, in both cases this signal must be encoded to NTSC and the quality of the encoder is the important factor.
