Graphics

I am trying to use Expressions version 3.6 to trigger 2 graphics on the Ross Vision switcher. The idea is to use it for going from an ots to a full screen graphic. The problem is that they are not synced. I am wondering which timing offset would work best for my Matrix to work as a cut function on the Vision.

If I understand you right Forogh, you are talking about a delay of live video shader in XPression. Then it is some 7 frames.

Maxim,

Is there a way to make the GPI trigger to process faster from the Vision to the Xpression software?

#XPression

I am afraid there is not, as the GPI is what it is. While composing your custom control macro on Vision you do need to mind all delays and to insert pauses. If the delay is too big please consult the techsupport.

Also, are you trying to send two GPI commands at once? In order to start two graphics together you can use a script in XPression that starts two separate scenes on different layers. Could you please provide with more details on what you want to achieve. I'm sure there is a recipe.

Thank you so much for your help. Okay, lets back up here...How do you make a GPI on vision for like a cut function going from vision to cut and Expressions to advance? I am sorry but I hate manuals.

I would suggest to program a custom control macro for that.

The idea is to assign [I]CG source[/I] to, say, [I]Key4[/I], then set [I]Key4 [/I]onair, at the same time to trigger the GPI and to do the Cut transition.

I assume you have a GPO setting configured to send a command to XPression that does what you expect, and the GPO is [I]Pulse High[/I] with a duration of 3 frames.

1. So, let's start recording a new custom control.

Go to Home; Custom Controls

Select a button you want your CC to be assigned to. (if you use banks, then select desired bank). You can do it either with the knob on the touch display or by pressing a button directly on Custom Control Bus row.

Press Start Recording

2. Press Sel button for [I]Key4 [/I]on [I]Keyers [/I]module.

3. Select your CG source on the [I]Key bus row[/I].

4. Choose AUTO SELECT on [I]Keyers[/I] module.

5. Compensate the actions above by inserting a pause.

Choose on the display Insert Special; Special; Custom Control; Pause CC

Insert 3 frames.

6. Activate Key4: choose on the display Insert Special; Special; Transitions; Cut Keys; Insert Cut Key ON (choose Key4)

7. Trigger GPI: choose on the display Insert Special; Special; Trigger GPI; Select GPO#. Press Insert.

8. Insert a pause: Insert Special; Special; Custom Control; Pause CC. Here you adjust how long the switcher wait before it does the transition. This is how long XPression reaction takes. Let's assume it is 10 frames. Do select 10 frames.

9. On [I]Transition [/I]module press BKGD, then press Cut.

10. On the display choose Finish Recording.

11. Give a native name to your custom control. Home; Custom Controls. Select your CC. Press Modify Name. Name it something like OTS-FSG. Confirm to save.

After you have done all this, you get a button on your CC row that does exactly what is declared at points 2-9 above.

Please notice that you may need less or more or shorter or longer pauses. The recipe is given as just an idea.

If it doesn't work for you, please double the question at Vision Community.

Best regards, good luck!
