HD will not fit into a PAL monitor. Too many lines, too high line frequency. This can make things a
little awkward for location monitoring and viewing.
The HDW-750P / 730S however,comes with a number of standard and optional output signals that
should give you what you need.
Firstly there’s an HDSDI output. HDSDI is a similar idea to the SDI signal that is the de-facto digital
interchange for standard definition. It just sends a lot more bits per second. (1500 Mbps as opposed
to 270Mbps for SDSDI.) Unfortunately we’re going to have to get used to the fact that there are now
two flavours of SDI, and they don’t mix.
Use the HDSDI output to connect to an HD monitor with an HDSDI input card. This is the signal you
should use for critical picture monitoring, or to send to a separate HD VTR or disk recorder for a
parallel recording or copying.
HDSDI is a very high frequency signal, so it doesn’t go very far down an ordinary BNC cable…about
40m maximum.
The test out BNC supplies an analog luminance (Y) HD signal that can be fed to an HD monitor with
a component input. It will only show a monochrome picture, as it’s only luminance, with no colour
components, but you can use it to check framing or view menus.
However…most camcorders are fitted with a down-converter option, that gives you several SD
monitoring options.
How do you tell if the down-converter option is fitted?
•
There will be an extra BNC connector fitted in a ‘bulge’ in the bottom right hand corner of the
side of the camcorder, pointing out of the back next to the 12V DC XLR connector.
From this connector you will be able to get either of the following, as chosen from the user menu:
• Composite PAL signal, that can be fed to any SD monitor with a composite input,
• SD SDI signal for good quality SD monitoring, or perhaps a Digi Beta
At the same time the test output can also now supply a composite video signal, so you could have
for example:
•
Composite video from the test output feeding floor monitors.
•
SDI from the down-converter output feeding a digi beta or DVCAM offline VTR
•
HDSDI feeding an HD directors monitor.
