+# 🦊 RS Split Video/Audio  
+**Splits the video into a silent track and a separate audio stream.**

+<img width="614" height="250" alt="Screenshot_1" src="https://github.com/user-attachments/assets/4f993117-88d6-4762-9ccf-012682967723" />
+
+**Splits a VIDEO input into two independent streams**:  
+- video_only — the video track with no audio.  
+- audio_only — the audio track as a standalone AUDIO object.
+
+**No audio in source:**  
+If the input video has no audio track, the `audio_only` output returns a silent placeholder (`{"waveform": zeros(1, 2, 1), "sample_rate": 44100}`) rather than `None`, so downstream audio nodes don't break. The node itself never raises for a missing audio track.
