The YouTube preset is a common mastering reference, not an upload rule. Auto Balance scans for standout loud sections and eases them smoothly before the final peak limiter. Manual EQ is neutral by default with gentle ±3 dB adjustments; it does not calibrate individual headphones or speakers.

Your browser processes media locally; no video or audio is sent to SoulsNote. On iPhone, the full replay is exported without trimming and the finished file is handed to the iOS share sheet so you can choose Save to Files. Keep Safari open, use Wi‑Fi or power, and make sure there is enough free storage. Optional video adjustments make MP4 export slower because the picture must be re-encoded. MP3 and WAV are audio-only exports.
