Video Reference
Generating Video Reference
The internal Video Reference generator, if enabled, locks (resolves) to the Internal Clock source.
To generate video reference:
1 Connect the VIDEO REF GEN BNC output ports on the back of Sync X to external video peripherals.
2 In the Pro Tools Session Setup window, select Internal for the Video Reference Source.
3 Select the appropriate Video Reference Format.
External Video Reference
To use external video reference:
1 Connect the external video reference output signal to the VIDEO REF IN BNC port on the back of Sync X.
2 If applicable, connect VIDEO REF OUT 1 and/or 2 BNC ports to the video reference input for other devices. Signal received
by
VIDEO REF IN is mirrored out the VIDEO REF OUT BNC ports.
3 Select External as the Video Reference Source.
4 In the Pro Tools Session Setup window, select the desired Clock Reference Source.
5 Enable enable Auto-Detect Format or select the appropriate Format.
Positional Reference
The following sections provide additional information for the available Positional Reference settings.
LTC (Linear Time Code)
LTC is used for positional reference when making ADM masters from Dolby Atmos mixes. Use Pro Tools | Sync X to generate
LTC for the Dolby Atmos Renderer (RMU).
LTC is often striped onto an ATR or VTR audio track. Professional VTRs typically have an address or cue track, intended for LTC.
If you are working with a standard audio tape, you will almost certainly be working with LTC. If you are working with a videotape,
you may be able to work with LTC. Many digital-format VTRs output simulated LTC from data stored in a recording.
LTC is delivered to Sync X as a series of audio pulses, regardless of how it is stored or generated.
To use LTC for Positional Reference with Sync X:
 In the Session Setup window, select LTC as the Positional Reference Format.
Serial Time Code
Pro Tools | Sync X provides a 9-pin port that can be used with MachineControl-enabled systems to remotely control 9-pin trans-
ports with Serial Time Code.
For MachineControl-equipped Pro Tools systems, Serial Time Code from the 9-pin port can be used for positional reference. This
option is configured from the Peripherals dialog. For details on using Serial Time Code with Sync X, see the MachineControl chap-
ter in the Pro Tools Reference Guide.
