 ## Variables
 - **inputs**: `a`, `b`, `c`, `d` (matches node input type)  
 - **Extra floats**: `w`, `x`, `y`, `z`   
-- **Tensor positions**:  `C` (channel), `B` (batch), `X`, `Y`, `W` (width), `H` (height) (not for FLOAT/AUDIO/CONDITIONING)
+- **Tensor positions**:  `C` (channel), `B` (frame number in image part of VIDEO node and BATCH everywhere else), {`X`, `Y`, `W` (width), `H` (height)} (not for FLOAT/AUDIO/VIDEO (audio part)/CONDITIONING)

-  - `S` – current audio sample (AUDIO only)  
-  - `T` – audio length  (AUDIO only)  
-  - `R` – sample rate (AUDIO only)  
+  - `S` – current audio sample (AUDIO and audio part of VIDEO only)  
+  - `T` – audio length  (AUDIO and audio part of VIDEO only)
