Scipt: How to change video input asignement with a single key

[Ivan Grigoriev]

Hi

I have a show with three live cameras and one is giving troubles, so till I find the problem I would like to create a script that invoked with a keystroke changes video input patch to a backup source.
I've used simple scripts before but I usually fail on the syntax area :-)
Thanks in advance!

Use OSC

(QLab 4)

/cue/{cue_number}/cameraPatch {number} 

QLab 5

/cue/{cue_number}/videoInputPatchNumber {number}

Or if you really need to script it

(QLab 4) set the camera patch of cue "1" to 1

(QLab 5) set the video input patch number of cue "1" to  1

Hi Mic

I think I did't explained myself correctly in the post

I have multiple cues that use that input, so I want to change the patch itself in the preferences. 

To picture the exact situation in Patch 1 there is a Blackmagic Decklink Duo Input 1 assigned, I would like to change that input to a NDI input with a keystroke (I've tried doing it opening the preferences and it works)

Is it possible)

Thanks!

You can’t

Use the OSC with a wildcard e.g /cue/*/videoInputPatchNumber {number} and all the camera  cues will change input.

Although I said you can’t,  you could with UI scripting, which is fiddly and unreliable,

The OSC  wildcard method is probably as quick.

OK, Can I select several non contiguous cues?

[micpool]

To do that you would need to number the cues with a prefix, so your Camera A cues might be numbered CAMA1… CAMA2 etc.

Then your wildcard to change only all CAMA cues would be /cue/CAMA*/videoInputPatchNumber {number}

you're "un capo!" (I'm from Argentina)

I've been trying with C1,C2,C3 and C1-C2-C3 with no luck. so I made a group with individual Cues for each change (there are 6) and it worked.

Now I'll fix it with the more elegant solution you gave.

Thanks!!!!

You can also use scripts to do this without having to number the cues  with a prefix

--to change every camera cue patched to Input 1 to input 4

tell application id "com.figure53.QLab.5" to tell front workspace
set theCamCues to cues whose q type is "camera" and video input patch number is 1
repeat with eachcue in theCamCues
set the video input patch number of eachcue to 4
end repeat
end tell

--to change every camera cue patched to Input 4 to input 1

tell application id "com.figure53.QLab.5" to tell front workspace
set theCamCues to cues whose q type is "camera" and video input patch number is 4
repeat with eachcue in theCamCues
set the video input patch number of eachcue to 1
end repeat
end tell

And for completeness here's how to UI script the video input patch, although because you need to have the settings open on the right tab, I don't recommend this for general use.

--change Camera Patch in Settings/Video/Video Inputs window  WHICH MUST BE OPEN
tell application "System Events" to tell application process "QLab"
tell pop up button 1 of UI element 3 of row 1 of table 1 of scroll area 2 of (first window whose name contains "Settings") --Patch 1 is Row 1 Patch 2 is Row 2 etc.
click
delay 1 -- 1 sec is for demo use 0.2 for normal use
click menu item 8 of menu 1 --In Pop up menu count items from top including dividing lines and sub menu names
end tell
end tell

Thanks Mic

your explanation can't be more complete.

I'll stick with the OSC solution because it is already implemented, although the script  (not the UI one) is easier to implement on an already running cue list.
