Time Base Corrector
T he MXPro contains a T ime B ase C orrector (TBC) that ensures top quality results in
your productions. The TBC operates automatically at all times. You don’t have to do
anything special to use the feature.
TBC compensates for image “shifting” and “wavering” that occurs with many VCR’s,
camcorders, and other video devices. It modifies the video signal so that all elements in
the picture — lines, fields, frames, and individual dots (or, pixels) — appear on the
OUTPUT screen exactly where they should. This improves video signal quality
significantly.

You can use the MXPro TBC as a dedicated, two-channel device to induce time base
correction on two separate channels. Set up your equipment as follows:
1
Set up the video devices normally — that is, make one the CURRENT source and
make another the NEXT source.
2 Press DISPLAY so that the Preview screen shows the NEXT source. (See “Display”
beginning on page 73 for instructions.)
The CURRENT source appears on the Output monitor. So the two sources each appear
on separate monitors, and both have the benefit of time base correction.
While operating in Dual TBC Mode, MXPro can perform cut transitions as it normally
does. Use the
CUT buttons to change the CURRENT source — the one displayed on the
Output screen. Use the NEXT buttons to choose the NEXT source — which appears on
the Preview screen.
