In the External Timecode Offsets section, Pro Tools lets you compensate for devices that are consistently offset by a fixed number of frames (such as some color–corrected video masters), or for material that starts at a different time than the session.
Pro Tools provides four different types of External Timecode Offset settings. These offsets include:
|
Synchronization peripherals, including SYNC HD (Avid HDX, Pro Tools|HD, and HD Native systems only), or other peripherals (such as MIDI interfaces that provide MIDI Timecode).
|
|
|
Satellite (Avid HDX, Pro Tools|HD, and HD Native systems with Satellite Link or Video Satellite, or Pro Tools with Video Satellite LE)
|
Unique values can be defined for each of these types of offsets, or you can link all to adjust in unison.
Positive and negative offset values can be entered to offset Pro Tools timecode display later or earlier, respectively.
If you are using the MachineControl option, additional options for External Timecode Offsets are available. See the MachineControl Guide for more information.
2 In the Redefine External Timecode Offset dialog, enter the offset you want in the Desired Timecode Position field.
This field lets you set a trigger offset for incoming MIDI Timecode (anywhere from –100000 to +100000 samples). This lets you create a permanent offset to fine-tune the point at which Pro Tools synchronizes relative to incoming timecode. For example, a value of –50 makes an event in Pro Tools occur 50 samples before the same event in the incoming MIDI Timecode. Use this to compensate for timing differences between various SMPTE-to-MIDI Timecode converters or analog-to-digital/digital-to-analog converters.
