Use the
Field Ref
pushknob to select the field on which the transitions
are executed:
Either – Executes a cut or begins a transition at the boundary between
the current field and the next, whether it is Field 1 or Field 2. This is
the default setting.
F1
– Executes a cut or begins a transition only at the boundary between
the end of Field 2 and the beginning of Field 1.
F2 – Executes a cut or begins a transition only at the boundary between
the end of Field 1 and the beginning of Field 2.
Aux/Txt Retime
This softkey appears only when the optional internal DVE is installed in
the 8150.
You can use any 8150 source except DSK Preview as a video input to
either channel of the DVE, and the DVE retimes itself for that source.
You can also use any direct source (defined below) in the 8150 as a
texture input to either channel of the DVE. However, because there may
be a timing difference between the DVE video input and the DVE texture
input, the 8150 must compensate for this difference. Because there are
not dedicated delay paths for the DVE texture inputs, the 8150 must
"borrow" the Aux 3 and/or Aux 4 retiming paths in the event that the
selected DVE video and texture inputs are not zero timed to each other.
The
Aux/Txt Retime
control allows you to select the following modes:
Aux 3/Aux 4
– All Aux 3 and 4 sources are correctly timed, but DVE
Channel A and Channel B texture sources may not be. Select this mode
if you need to use the Aux 3 and 4 outputs or are not using the DVE
texture inputs.
Aux 3/Txt A
– All Aux 3 sources and DVE Channel A texture sources
are correctly timed, but Aux 4 and DVE Channel B texture sources
may not be. Select this mode if you are using only the DVE Channel
A texture input, such as in V+K or VK+S modes, and need to use the
Aux 3 output only.
Txt A/Txt B – All DVE Channel A and Channel B texture sources are
correctly timed, but Aux 3 and 4 may not be. Use this mode if you are
using both DVE texture inputs in V+V mode or do not need the Aux
3 and 4 outputs.
Each of the three modes is explained in the table on the following page.
Note that the DVE video input selections affect the functionality of these
modes. Even though any source in the 8150 (except DSK Preview) is
valid as a DVE video input, only a direct source is valid as a DVE texture
input. A "direct source" is defined as a source in the 8150 that is not
delayed by internal processing, i.e., inputs 1 through 14, the SuperMatte
