+## Pixel Spatial Upscaler IC-LoRA
+
+We provide **Pixel Spatial Upscaler** IC-LoRAs that creatively upscale low-resolution video by synthesizing fine detail rather than simply interpolating pixels. Given a low-resolution reference clip, the model re-renders it at 2× or 4× resolution with generative spatial detail — making it a creative upsampler, not a pixel-accurate refiner.
+
+### Key Features
+
+- **2× and 4× variants**: Choose the 2× upscaler for moderate upscaling or the 4× upscaler for larger resolution jumps.
+- **Generative detail synthesis**: The model synthesizes texture and structure from the reference rather than faithfully preserving every pixel.
+- **Draft-then-upscale workflow**: Generate at a low base resolution (e.g. ~280p) to lock in composition and motion, then run the upscaler for the final high-resolution output.
+- **Tunable fidelity**: LoRA strength, guidance, and step count control how closely the output follows the reference — lower values stay closer to the source; higher values allow more creative detail.

 ## Text-to-Audio (T2A)
 
 LTX-2 is a single joint audio/video transformer, but it can generate audio on its own. The `LTXVAudioOnlyModel` node puts the model into audio-only mode for text-to-audio, with no video output.
