•The Sync Clock defines on which clock source the frame playback is based on.
•Different options for a clock source are: System Clock, ASIO Audio, Wave Audio, SMPTE IO LTC, GPU Sync and Local Clock
•Please also read the Playback Sync- chapter, when working in session mode.
Settings
•Select your System and go to the Inspector
•Focus Settings tab there
•Select your preferred clock source in the Sync Clock dropdown list
Top bar: green underlined clock indicates the system clock is synchronized correctly.
This is especially important for a project in session mode.
If the system clock is underlined red, there is something wrong with Playback Sync and the Sync Clock
Changing Clock Source can affect the Playhead's position
After selecting another clock source, the Playhead could jump to another position in the timeline.
This only happens once directly after a switch of your clock source
System Clock
Playback is locked on the VERTEX System Clock. Recommended when working without audio.
ASIO Audio
Recommended: plugged and connected Audio device/interface with ASIO driver
VERTEX is clocked by the ASIO devices Clock.
Audio and Video Playback with Audio over ASIO Interface
To prevent from a shift between audio and video we recommended to use the ASIO clock as system clock. The Video Playback and Frame processing in VERTEX is synchronized to the Clock signal from the ASIO device
When you select an ASIO device in the audio settings of a system, VERTEX automatically sets the Sync Clock from Wave Audio to ASIO Audio.
Wave Audio
By default, VERTEX playback is locked to the clock of your Standard Audio device, which is in most cases your built-in sound card.
In the System Audio Settings, when changing the "Wave Audio Mode" from "Preview" to "Live", the Sync Clock automatically is changed to "Wave Audio"
SMPTE IO LTC
Longitudinal Timecode can be received via ioversals SMPTE IO Interface
Get all information about clock and playback settings in the chapter SMPTE
GPU Sync
Syncs VERTEX Playback to the GPU Clock.
When using this option, you have to define a GPU sync master system. Go to Advanced Mode in the Inspector and search for "Is GPU Master" Property (Setting tab in the Inspector).
There is also an Advanced Property to set the "GPU sync interval" manually.
If there are questions about a GPU sync setup, feel free to drop us an email with your specific questions and a description of your hardware!
Set Sync Clock In A Session Mode Project
Please read also the Multi Systems chapter. The topic Playback Sync explains how to set up the system clock in a Project.
All Systems in a session mode project, excluding the Clock Master System need to be set to the same clock.
The Clock Master generates a System Clock for all other Systems. Please read the chapter Playback Sync.
