Q: I have a Panasonic WJ-X30 video mixer and a stand-alone time-base corrector. Where does it go
in the system, before or after the mixer?
A: A TBC should always follow the video output of a playback VCR, not after your
Panasonic MX-30 or any other digital mixer. If possible, connect the appropriate sync
cables from the MX-30 to the “sync in” on the TBC and to the “external sync
in” jacks on the playback VCR if it has one. This insures that all three pieces of
equipment are “marching to the beat of the same drum.” The same
hold true if you have a Panasonic WJ-AVE7.
Q: How do I apply digital effects (strobe, negative, mosaic) to both buses of the
Panasonic MX-30 or Panasonic AVE-7 when there’s only one row of effects buttons.
A: With the MX30 or AVE7 video mixer, the digital effects buttons perform double duty. Look
next to the on/off button for the digital effects on the Panasonic MX-30 video
mixer, you will see two buttons
labeled A and B. The desired bus to which you wish to add effects to is selected by
pressing the “A” or “B” buttons in the digital effects section of your
mixer. Even though the LED light is not lit, you’ll still be getting effects on the
bus that isn’t selected at the time.
Q: Is it possible to freeze a compressed PIP with an Panasonic MX30 or Panasonic
AVE7?
A: Yes you can, however, don’t push the Still button until after the PIP has been
created. Also, you will loose the frame when you exit the PIP mode. On the
Panasonic MX-30 and
Panasonic AVE-7 video mixer, you loose the freeze-frames when entering or exiting the compressed PIP mode.
Q: Does the Panasonic MX-30 or AVE-7 have an “external sync in”?
A: The external sync in on the MX-50, MX-30, AVE-7 and AVE-5 is labeled “External
Camera In.” Any stable video signal from an external camera, an reference sync, black
burst signal, a genlock feed, or even the video output from most TBCs will connect to the
External Camera In on these mixers and make them sync up to the other timing source.
Q: Can you do a 3 camera live shoot with the
Panasonic AVE-7 or MX-30 video mixer?
A: Yes. Connect the third live camera to the external camera input. You can call up
the external camera to the main mix bus by pressing source buttons 1 and 2 at the same
time.
Q: I have seen a rainbow flagging after doing a video insert on a tape that’s
been pre-blacked with my Panasonic MX-30 video mixer. How can I prevent this?
A: Panasonic digital mixers generate black at 0 IRE. This is dangerously close to the
video sync part of the signal. The sync resides in 0 IRE to -40 IRE range. The NTSC
broadcast standards for the USA states “video black” should be set at 7.5 IRE.
You might want to try pre-blacking the video tape with a dark blue, which is at about 15
IRE. Or you can get 7.5 IRE black on the MX-30 and MX-50 by selecting the dark blue matte
background color and then turning the matte color level control all the way
counter-clockwise.
Q: How do you generate color bars on the
Panasonic AVE-7 video mixer?
A: Simply turn off the unit and then switch it back on while simultaneously holding
down the three gray buttons in the superimpose section.
Q: I trying to import an external wipe pattern into my
Panasonic WJ-MX30 video mixer. I am using a
Panasonic AG-1970 to play back the wipe pattern tape and feed it into the external camera
jack to use the External Key mode. However, my picture is completely breaking up.
A: In order to do this, the source VCR must be properly time-base corrected. The
AG-1970 has a pseudo-TBC that is suitable for dubbing, but not for true stability purpose.
The MX-30’s external camera input requires the signal to properly time-base
corrected. The source VCR must have a full-frame (or infinite window) TBC in order to feed
the External Camera input on your MX-30 since any signal that is applied to this jack
essentially becomes the synchronization reference signal for the entire mixer.
Q: I’ve tried plugging my professional low impedance microphone into the low
impedance XLR audio jacks on the back of the Panasonic MX-30 and I can’t hear a
thing. What gives?
A: With high-end video and audio equipment, both microphone level signals (-60 dB) and
line level signals (0 dB to + 4 dB) use XLR connections. On the MX-30, the XLR jacks are
for line level signals only (i.e. audio output from a playback VCR). Mic level signals
need to be “pre-amped” before they can become line level. On the
Panasonic MX-30 video mixer, there is
no pre-amplifier in line after the rear panel XLR jacks. To get mic level signals into the
the Panasonic MX-30 video mixer, you can use the 1/4” mic jack on the front of the
Panasonic MX30 video mixer or run your mic
through an outboard mixer or a microphone pre-amp first and then into the line level
jacks.
