COMPATIBLE CODES · EMOTIONS AND SCENES

    Tags come from collection tracks with that code. Counts show how many tracks have each tag. Analyze music or edit tags to fill the list.

    How to use codes in video editing
    1. Start with the track in your edit.

      Upload and analyze music. Read the code of the track ending in your sequence and select it here.

    2. Find music for the next sequence.

      Highlighted codes indicate compatible keys. Selecting a code keeps tracks with those codes in the list below.

    3. Listen to the transition in your video editor.

      Overlap the end of the first track with the start of the next. Adjust duration, volume and rhythm to your shots and dialogue.

    Uppercase and + = major; lowercase and - = minor. Pairs follow the circle of fifths, starting with AB+ · C major and ab- · A minor. The code indicates key, not BPM or intensity. Compatibility helps you choose; check the result by listening.

    HARMONYZER

    From track to Harmonyzer code.

    1. Upload your music.

      Select one or more tracks from your device.

    2. Select “Analyze tracks”.

      Harmonyzer always analyzes 5 excerpts distributed across the track, locally in your browser. Windows may overlap in short files. The code with the most votes is assigned automatically; tied votes use model scores.

    3. Check the results.

      Correct the Harmonyzer code and BPM in each track's row. ÷2 and ×2 adjust tempo. In Details, listen to analyzed excerpts and apply an alternative key. Tracks with a key estimate receive the voted code automatically and are selected for export. “Majority code” means excerpts produced different results; Details shows the votes. Files without a key estimate remain available for manual assignment.

    4. Select tracks for export.

      Use “Select all” for the analyzed collection. To select by criteria, apply filters and choose “Displayed only”; this selects displayed tracks with connected files and an assigned code. Adjust individual checkboxes as needed. After analysis, the Emotions, Scenes / moments and Wedding moments tabs appear. Filters use suggested or corrected tags. Open Edit tags to confirm several emotions and scenes per track. Combine the three filters or reset them together. Weddings have 47 Wedding Moments Music moments, searchable by translated name, original Romanian/English name or number. Wedding suggestions follow track emotions. In Edit tags, see associations, confirm several moments or choose others. Apply a moment to displayed tracks.

    5. Choose the filename format and save.

      Choose a template and separator in Filename format, then check the preview. Export includes selected tracks, even those hidden by filters. Download individual files, a ZIP or export into a chosen folder. Folder export creates a Harmonyzer subfolder for renamed copies. Original files on your computer stay intact. Audio is not re-encoded. If Comments is enabled, emotions, scenes and wedding moments are written into the exported copy's metadata.

    6. Test transitions in the timeline.

      Choose the first track in the picker or with “Add to timeline” in the track list. Subsequent tracks must be compatible with the last one. Drag excerpts to reorder, adjust source start/end and choose the overlap with the next excerpt. The player auditions the edit locally in your browser. Filter the next track by a WMM moment and assign a film moment to each excerpt. The timeline is saved with your session. In Export for editing, choose Premiere Pro or DaVinci Resolve, the project FPS and download XML alone or XML + audio. Continue trimming and adjusting transitions in your editor.

    7. Return to a session.

      Results are saved automatically in this browser. Open Sessions to return to a collection, then reconnect the original files or folder. Manual corrections are kept.

    How do you read the code?

    AB+ is C major; ab- is A minor. Shared letters show neighbors in the circle of fifths: for ab-, look for ab-, la-, bc- or AB+. Uppercase and + = major; lowercase and - = minor. The circle closes through KL, LA and AB.
