Using Apple Script to set slice times

[ben.sti...@gmail.com]

Hello All

Attempting to use an apple script yo set the time points of slice times and seeming to run into a brick wall I keep getting the error code :

"QLab got an error: Can’t set slice marker record 1 of cue "VIDEO1" of workspace 1 to "2.54"."

Am using Q lab 4.2.3

Code:

using terms from application "QLab"

tell application id "com.figure53.QLab.4" to tell front workspace

tell slice marker record 1 of cue "VIDEO1"

set time to "2.54"

end tell

end tell

end using terms from

I am guessing that its one of the below :

• using the wrong format for the time 
  
• not correctly targeting the slice marker record 
  
• I am trying to do something Q lab can't do 
  

Cheers, 

Ben

Use OSC instead

e.g

/cue/VIDEO1/addSliceMarker 2.54

Or if you need to calculate the time or get it from somewhere else  use something like this script

tell application id "com.figure53.QLab.4" to tell front workspace

set markertime to 2.54

set oscCmd to "/cue/VIDEO1/addSliceMarker " & (markertime as string)

do shell script "echo " & oscCmd & " | nc -u -w 0 127.0.0.1 53535"

end tell

The AS form is like this:

tell front workspace

set selectedCue to last item of (selected as list)

set sliceMarkers to slice markers of selectedCue

if (count sliceMarkers) is 0 then -- No existing slices

set sliceMarkers to {{time:123.4, playCount:1}}

else

set item 1 of sliceMarkers to {time:123.4, playCount:1}

end if

set slice markers of selectedCue to sliceMarkers

end tell

Records are a bit weird to work with. playCount  of -1 for infinite loop. You’ll need to dress the code up a bit to fit your context.

Thank you both that is exceedingly helpful and now I know that you have to write it back to Qlab a a list make a lot more sense.

Hey Rich,

I'm using the following AppleScript but getting the following error: "Invalid slice marker time"

using terms from application "QLab"

tell application "QLab" to tell front workspace

set last slice infinite loop of cue "LOGO-BG" to true

set OldSlice to slice markers of cue "LOGO-BG"

set NewSlice to {{playCount:1, time:8.0}}

set slice markers of cue "LOGO-BG" to NewSlice

Hi DC,

I have been having a play around with this and I think the issue might be that the cue needs audio for it to work, so far when I tired that script the first few times it ran perfectly fine no issues. I then swapped the same cue for a vidoe with no audio and got that error. 

Possibly its some way Qlab handles loops requires audio when setting slice markers via apple script ?
