FolderBitrate (Columns with average bitrates for video files in folders)

Buttons/Scripts

Last update: 2025-05-19

This add-in creates two script columns: AudioBitRateAvg and VideoBitRateAvg.

For folders, these columns display the average audio and video bitrates of the video files within the folder. By default, subfolders are excluded, but recursive scanning can be enabled in the script settings.

For individual files, the columns show the same values as the standard columns video.mp3bitrate and video.datarate.

How to set up and use

:one:

Save ColumnFolderBitrate.js.txt to   ↓

%appdata%\GPSoftware\Directory Opus\Script AddIns

:two:

Toggle the columns with

Set COLUMNSTOGGLE="scp:FolderBitrate/AudioBitRateAvg(!,a,0)"
Set COLUMNSTOGGLE="scp:FolderBitrate/VideoBitRateAvg(!,a,0)"

Open the settings with

Prefs SCRIPTS=ColumnFolderBitrate.js*

The script's inner workings

JScript 
function OnInit(initData) {
    initData.name = 'FolderBitrate';
    initData.version = '2025-05-19';
    initData.url = 'https://resource.dopus.com/t/folderbitrate-columns-with-average-bitrates-for-video-files-in-folders/53491';
    initData.desc = 'Display Average Audio and Video Bit Rate for folders.';
    initData.default_enable = true;
    initData.min_version = '13.0';

    initData.config_groups = DOpus.Create().OrderedMap();
    initData.config_desc = DOpus.Create().OrderedMap();
    initData.config = DOpus.Create().OrderedMap();

    initData.config_group_order = DOpus.Create().Vector('Misc');

    AddConfig('recursive', 'Misc', 'Include subfolders in calculation', DOpus.Create().Vector(0, 'no', 'yes'));

    function AddConfig(name, group, desc, value) {
        if (group) initData.config_groups.set(name, group);
        if (desc) initData.config_desc.set(name, desc);
        initData.config.set(name, value);
    }
}

function OnAddColumns(addColData) {
    var col = addColData.AddColumn();
    col.name = 'AudioBitRateAvg';
    col.method = 'OnColumn';
    col.justify = 'right';
    col.type = 'double';
    col.multicol = true;

    var col = addColData.AddColumn();
    col.name = 'VideoBitRateAvg';
    col.method = 'OnColumn';
    col.justify = 'right';
    col.type = 'double';
    col.multicol = true;
}

function OnColumn(scriptColData) {
    var item = scriptColData.item;

    var bitrateAudio = 0;
    var bitrateVideo = 0;
    var countAudio = 0;
    var countVideo = 0;

    var flags = Script.config.recursive ? 'r' : '';

    if (item.is_dir) {
        var folderEnum = DOpus.FSUtil().ReadDir(item, flags);
        while (!folderEnum.complete) {
            var folderItem = folderEnum.Next();
            var meta = folderItem.metadata;
            if (meta != 'video') continue;

            var d = meta.video.mp3bitrate;
            if (typeof d == 'number') {
                bitrateAudio += d;
                countAudio++;
            }

            var d = meta.video.datarate;
            if (typeof d == 'number') {
                bitrateVideo += d;
                countVideo++;
            }
        }
        folderEnum.Close();
    } else {
        var meta = item.metadata;
        if (meta == 'video') {
            bitrateAudio = meta.audio.mp3bitrate;
            if (typeof bitrateAudio != 'number') bitrateAudio = 0;
            countAudio = 1;

            bitrateVideo = meta.video.datarate;
            if (typeof bitrateVideo != 'number') bitrateVideo = 0;
            countVideo = 1;
        }
    }

    scriptColData.columns('AudioBitRateAvg').value = (countAudio ? bitrateAudio / countAudio : 0).toFixed(1);
    scriptColData.columns('VideoBitRateAvg').value = (countVideo ? bitrateVideo / countVideo : 0).toFixed(1);

Bro do you machine was or dry clean your cape? True hero my friend. True hero.

This is fantastic, but is there any way to get it to include sub-folders as well?

Yes. I have added an option for recursive scanning to the script.
