ExtendScript performSceneEditDetectionOnSelection doesn't analyze clips

[EditMan]

Hey everyone,

I'm trying to detect cuts in a sequence via ExtendScript in Premiere Pro using the following bit of code:

var activeSeq = app.project.activeSequence;

activeSeq.performSceneEditDetectionOnSelection("ApplyCuts", true, "LowSensitivity");

The Scene Edit Detection dialogue pops up and it says analyzing clips, but the progress bar never advances.

I've tried changing the sensitivity and using the "CreateMarkers" action instead but it still says Scene Edit Detection regardless of which string I use for the first parameter and progress bar never moves.

I've confirmed that the Scene Edit Detection functionality works when I right click the media in the sequence and initiate the process manually. I'm on Premiere Pro 24.5.0 (Build 57).

Any help would be appreciated. Thank you!

I've confirmed that PProPanel's scene detection works correctly in 24.5.0x57.

Is the failure specific to a given sequence or project? 

Does [below] work?

var activeSeq = app.project.activeSequence;
if (activeSeq) {
	var sel = activeSeq.getSelection();
	if (sel) {
		var action 							= 'ApplyCuts';	//'ApplyCuts', 'CreateMarkers'
		var shouldApplyCutsToLinkedAudio	= true;
		var sensitivity 					= 'LowSensitivity'; //'LowSensitivity', 'MediumSensitivity', 'HighSensitivity'
		var result = activeSeq.performSceneEditDetectionOnSelection(action, shouldApplyCutsToLinkedAudio, sensitivity);
	} 
}

Hey Bruce,

This issue occurs on multiple sequences across multiple projects.

I was able to get both versions of the code to analyze the clips successfully by selecting the media on the timeline before running the code. If the sequence is active but none of the media is selected on the timeline, then the analyze clips progress bar never advances.

Is this working as intended?

Yep; The example code is checking for a selection within the sequence. You don't have to. 🙂

hi 🙂
having the same problem.

when developing the feature using the performSceneEditDetectionOnSelection works good, but when sending the relevant ZXP to the QA we have the same problem in his premiere (The Scene Edit Detection dialogue pops up and it says analyzing clips, but the progress bar never advances).

we have active sequense so this solution dont work for us.

some details:
* the development was with premiere 23.
* the qa have premiere 25/24.3

The solution was not to have an active sequence; the solution was to have track items selected.

ok, but in my env this work so maybe this is other problem?

[Bruce Bullis]

Hard to say, without specifics. 

Recommendation: Set breakpoints and debug on a QA's system, and confirm that all the parameters you're passing to performSceneEditDetectionOnSelection() are valid.

[WSC21881869yc76]

did that and looks good.
i think i will add the selection anyway to the code to check if this is working.
what is the best way to select the track items in the api code?

[Bruce Bullis]

See lots of examples of calling trackItem.setSelected(), in PProPanel.

Thank you! I think this solve my problem.
there is a problem working with mxf in premeire 25 version?
the app is carching when trying to import mxf file.

[Bruce Bullis]

I don't know of any MXF issues; I'd recommend starting a new, non-ExtendScript-related thread in which to discuss such issues. 🙂

Amazing! Thanks Bruce!
