So, let’s see what kinds of things you can do
with PROCESSING. When you press the button,
you can cycle through five parameters - Scaling
Type, Out Zoom, Audio Delay Time, Sync
Source, and TC Generate - and select settings for
each.
Scaling Type lets you set the aspect ratio.
Since selecting 4:3 would otherwise cut strips
from the sides of the screen, you can choose
between Squeeze or Letterbox. Appropriate
options are also available for 16:9 video as well.
Out Zoom is especially effective when down
converting. You can adjust the zoom amount
from 50% through 150%, and when enlarging the
screen, you can set positioning via menu options.
There is more about this in the description of
PROCESSING parameters on page 10.
By setting Audio Delay Time you can adjust
the amount of delay between the video and
soundtrack. This is especially useful if spoken
words are out of synch with the movement of lips
with the video. Fine tuning and adjustment can
be as little as 0.01 frames. The default setting is
1.00 f to compensate the audio timing to match
the delay resulting from the video conversion
process.
Sync Source lets you set the reference for
synchronization. The VC-300HD provides three
options: Internal, Video Input, and REF Input. If
not set manually, the optimal source will be
automatically be selected. When converting
between PAL and NTSC, if input and output are
out of sync, internal synchronization is selected.
If no external synchronization signal input is
detected, synchronization is almost always set to
Video Input. When conversion is output to a
recorder, the input signal of the recording device
works as the reference. Consequently, Auto
detection usually presents no problems. When
input is to a switcher or other source that requires
synchronization, sync is accomplished via an
external input.
With TC Generate you can select what to do
about the embedded time code when using
i.LINK and HD-SDI connections. When OFF is
set, no code is output. Free Run uses the value set
in the VC-300HD. When Thru is set, the time
code that is sent via i.LINK and HD-SDI is
embedded as it is. Using Offset, output can be
adjusted with an embedded value applied to the
time code. Thru output applied to incoming HDV
is particularly convenient when you want to
match offline and online time code data.
