Setup guide

Is:Where:
The delay in milliseconds after a vertical sync, before requesting the VTR timecode.
This value should only be set or changed with the help of technical support.
NOTE The value '99' is a special case to be used strictly with HDCAM-SR/720P
and AJA. It is not to be used in other circumstances unless specified by technical
support.
<TC_transition_delay>
The delay in frames before the edit sync point to send the ON command. This
parameter is optional and it applies only to BVW50.
<edit_on_delay>
The delay in frames before the edit sync point to send the OFF command. This
parameter is optional and it applies only to BVW50.
<edit_off_delay>
The delay in milliseconds before the application sends certain commands to the
VTR. This parameter is optional, but useful for older VTRs such as the BTS.
<vtr_command_delay>
NOTE The init.cfg file contains a comprehensive list of VTR keyword examples for supported VTRs and HSDL
devices. In most cases you just have to uncomment the lines for the device that you want to use. In some cases
minor changes to parameters are required.
Configuring Colourspace Conversion for Device I/O
When you set the input or output format for a VTR or HSDL device in the Vtr keyword, you should also
specify its colourspace conversion method using the <colorspace mode> parameter. The supported
conversion methods depend on whether a single-link or dual-link connection is used for I/O with the device.
The following table shows the colourspace conversion methods that are available for single-link and for
dual-link I/O connections.
Supported for Dual-Link Serial
(4:4:4) I/O
Supported for Single-Link Serial
(4:2:2) I/O
Colourspace Conversion Method
NoYesYCbCR -> RGB
NoYesYCbCR -> RGB + Headroom
YesNoNo Conversion
YesNoNo Conversion + Headroom
Emulator
Use the Emulator keyword to enable the VTR Emulation feature and configure your workstation to emulate
a Sony
VTR that is controllable via the RS-422 serial port. For help configuring the hardware for VTR
emulation, see the Autodesk Visual Effects and Finishing Hardware Setup Guide for your workstation.
The VTR Emulation feature supports SD and HD video timings. This feature is available in Backdraft Conform
and Smoke 2K.
You can specify more than one emulator. Any enabled emulator can be selected for a project, regardless of
the project's video I/O timings.
The Emulator keyword uses the following syntax
Emulator sony, <name>, <input_format>, <timing>, <colorspace_mode>,
<output_format>, <output_sync>, <serial_port>, <emulator_output_delay>,
