0 IRE
Applies a setup level of 0 IRE. You should select this option
only
when working
with a commercial DV device that uses the Japanese analog NTSC setup of 0 IRE. For
example, if the video appears too bright when you play back DV clips on your NTSC
monitor, you can change the setup to 0 IRE to output your DV clips at the correct
brightness.
¦
Note
If your device has a different NTSC setup level for input and output, you can
switch the setup level as needed before capturing or recording to tape. If you’re not sure
which setup level your DV device uses for input and output, check with your device’s
manufacturer.

(TBC). RTMac will filter the video input signal to
increase tolerance for sync pulse instability.

Broadcast-quality
Select this if your source device meets broadcast-quality
standards, such as a device with a built-in time base corrector. This allows RTMac to
digitize the input signal as-is.

A
time base corrector
(TBC) is an electronic device that, when connected to the output of a VTR,
corrects the stability and timing of the VTR’s playback video. This is achieved by stripping the
unstable horizontal and vertical sync pulses from the video signal, and replacing them with new, clean
sync pulses.
