Since you're getting old and senile.

1) Run node script to output files in date order to a file.

var recursive = require('recursive-readdir');
var fs = require("fs");

var inputFolder = process.argv[2];
if (!inputFolder) {
    console.log("** YOU GOTTA SPECIFY THE TARGET PATH AS THE FIRST PARAM! **");
    process.exit(1);
}

recursive(inputFolder, ['ff*', '.*'], function (err, files) {

    var filesOrdered = files.map(function (v) {
        return {
            name: v,
            time: fs.statSync(v).mtime.getTime()
        };
    })
        .sort(function (a, b) { return a.time - b.time; })
        .map(function (v) { return v.name; });

    filesOrdered.forEach(function (fileName) {
        console.log("file '" + fileName + "'");
    });
});

Then run that sucker
/Volumes/Slug Bug/node outputFile.js "/Volumes/Slug Bug/YourFolderHere" > files.txt

then review the ffmpeg documentation (LOL):
https://www.ffmpeg.org/ffmpeg-formats.html

then run

ffmpeg -f concat -i files.txt -vcodec mpeg4 -b:v max -s 1920x1080 -r 60 stx.mp4

rember the -f {{command}} indicates the input preference, not the operation! duh!
q q saves and quits. Read the text that flashes by. duh!
