Getting/setting Mark In/Mark Out points in project item opened in source monitor

Pinging @Bruce Bullis because I'm pretty sure you're the man I want 😉

Like the title says, I would like to programatically "Mark In" and "Mark Out" (keyboard shortcuts I and O) in a project item opened in source monitor. I find the correct project item to open in source monitor by comparing the file path like so:

if (projItem.name.toLowerCase() === videoFileName.toLowerCase()) {
    app.sourceMonitor.openProjectItem(projItem)
}

And would now like to also set the in and out points by given timestamps. I see that it's possible for a sequence, in e.g. the `exportCurrentFrameAsPNG` function in the PProPanel project:

var seq = app.project.activeSequence;
..

seq.setInPoint(currentTime.seconds);

Is there any way to use Markers perhaps? I'm already setting markers to a project item which are shown as expected when opening the video in source monitor.

Thankful for any guidance!

Correct answer Bruce Bullis

Once you've found a projectItem associated with the media open in the source monitor (your approach is sound), you can use projectItem.setInPoint() and .setOutPoint().

Thank you for the quick reply! Unfortunately I am not getting it to work. I can fetch the in and out points of the project item, but setting them gives me an error. Not sure what I am doing wrong? See code snippet below:

if (projItem.name.toLowerCase() === videoFileName.toLowerCase()) {
    app.sourceMonitor.openProjectItem(projItem);
    var inPoint = projItem.getInPoint(); // works fine, returns Time object at 0 seconds
    var outPoint = projItem.getOutPoint(); // works fine, Time object at ~14000 seconds (3.5h+ video)
    inPoint.seconds = 600; // confirmed inPoint was modified to 600s, i.e. 10min in
    outPoint.seconds = 1200; // confirmed outPoint was modified to 1200s, i.e. 20min in

    // projItem.setInPoint(inPoint.ticks); // EvalScript Error
    // projItem.setOutPoint(outPoint.ticks);  // EvalScript Error

    // projItem.setInPoint(inPoint.seconds); // EvalScript Error
    // projItem.setOutPoint(outPoint.seconds);  // EvalScript Error

    // projItem.setInPoint(inPoint); // EvalScript Error
    // projItem.setOutPoint(outPoint);  // EvalScript Error
}

Have you stepped through that ExtendScript code in the VSCode ExtendScript Debugger?

I ask, because it gave me a more informational error message (than just 'EvalScript Error'), which showed the actual problem... 😉

The docs for setInPoint() explain the second, non-optional parameter:

This code (which just acts on the first projectItem it finds) works.

var first = app.project.rootItem.children[0];
if (first){
	var inpoint	= first.getInPoint();
	inpoint.seconds = 16.234;
	var result = first.setInPoint(inpoint, 4);
}
