Need help making a script for saving as jpg with interval

Record the installed or browsed Photoshop script into an action, in the Bridge script I have named the set "Incremental" and the action "Save" to align with the Photoshop action.

Just in case the link to the previous post breaks at some future point:

#target photoshop

main();

function main() {
    if (!documents.length) return;
    var Name = app.activeDocument.name.replace(/\.[^\.]+$/, '');
    try {
        var savePath = activeDocument.path;
    } catch (e) {
        alert("You must save this document first!");
    }
    var fileList = savePath.getFiles("*.jpg").sort().reverse();
    var Suffix = 0;
    if (fileList.length) {
        Suffix = Number(fileList[0].name.replace(/\.[^\.]+$/, '').match(/\d+$/));
    }
    Suffix = zeroPad(Suffix + 1, 3);
    //var saveFile = File(savePath + "/" + Name + "_" + Suffix + ".jpg");
    var saveFile = File(savePath + "/" + Suffix + ".jpg");
    SaveJPEG(saveFile, 8); // JPEG compression level
}

function SaveJPEG(saveFile, jpegQuality) {
    jpgSaveOptions = new JPEGSaveOptions();
    jpgSaveOptions.embedColorProfile = true;
    jpgSaveOptions.formatOptions = FormatOptions.STANDARDBASELINE;
    jpgSaveOptions.matte = MatteType.NONE;
    jpgSaveOptions.quality = jpegQuality;
    activeDocument.saveAs(saveFile, jpgSaveOptions, true, Extension.LOWERCASE);
}

function zeroPad(n, s) {
    n = n.toString();
    while (n.length < s) n = '0' + n;
    return n;
}

#target bridge;
if (BridgeTalk.appName == "bridge") {
    var psRem = new MenuElement("command", "PS Auto Timer - Incremental Save", "at the end of Tools");
}
psRem.onSelect = function () {
    var mins = 60000 * 1; // 1 minute 
    psReminder = function () {
        var bt = new BridgeTalk();
        bt.target = "photoshop";
        // Run action set 'Incremental' & action 'Save' which calls a recorded photoshop script 'incremental-jpeg-saves'
        bt.body = "if(documents.length) app.doAction('Save', 'Incremental') alert('File auto-saved via running Bridge script')";
        bt.send(4)
    }
    id = app.scheduleTask("psReminder()", mins, true);
    var win = new Window("palette", "Photoshop Reminder");
    win.bu1 = win.add("button", undefined, "Stop Reminder");
    win.bu1.onClick = function () {
        win.close(0);
        app.cancelTask(id);
    }
    win.show();
};

A combination of a Bridge and Photoshop script will save auto timed incremental file versions.

As suggested by Nancy, screen recording will also show the interface. Some record video, some offer an image screenshot every N seconds.

Get dedicated screen recording software like Camtasia.  Techsmith lets you try before you buy.

I don't know if reverse engineering is authorized on that script, but check out Increment & Save Photoshop Script
