Hello, Usually CPU spikes are related heavy load in terms of video clip decode, but without additional logs from the system it is impossible to know for sure. I suggest opening a tech support ticket with Ross Technical support so the logs from the system can be uploaded and examined. techsuppo ...

Hello Jonathan, Unfortunately, user input controls do not currently support nodal data structures, so the only option for populating them from Datalinq would be sources that are parsed as columns and rows like databases and Text files. ------------------------------ Andrew Sampson Ross Video --- ...

RE: Setting an Xpression timer to a custom value via Datalinq

Found In Egroup: Facility Control \ view thread
Hi Dave, I'm not an expert when it comes to creating that listener but you could probably use similar parsing logic to that in the script I sent to set a Dashboard timer. Dashboard timers can then be configured to update parameters in your panel the values of which can be streamed to XPression using ...

Hi Dave, If I understand correctly you want to use that string being received from datalinq to set a timer widget in XPression, so nothing really required on the dashboard side? If so I have created a sample project that uses an onSetText Script to parse the incoming string and set a timer widget. ...

This is possible but requires scripting to accomplish. I'm assuming your ribbon consists of scene with a published object that you drop a clip onto is it also part of timed sequence group? On the dashboard side of things you just need to fire a rosstalk GPI at XPression. Fore example GPI 999. ...

Mike, to do this you need to use two text objects one which is datalinqed to the score feed the other not linked at all. The object receiving the data should be hidden and the one not receiving should be the one you display on air. On the hidden object you would run a script onSetText that evaluates ...

Your Best bet is to use object groups to achieve this. You are correct that visual logic will always set the scale of your object not allowing you to animate it, however, if you take that object and place it within a group object you can animate the parent node while visual logic affects the child ...

Anthony, have you tried to reopen the project yet? This is usually an indication the project file has been corrupted and XPression will not be able to reopen it. That being said, It should try to load a backup project from your last successful save. You will lose your work between the last successful ...
