-# InfiniteTalk Space - TODO for Completion
-
-## Critical: Inference Integration Needed
-
-The current `app.py` has a **placeholder** for the actual video generation logic. To complete the implementation, you need to integrate the actual InfiniteTalk inference code.
-
-### Steps to Complete:
-
-#### 1. Review Reference Implementation
-Check `temp-infinitetalk/generate_infinitetalk.py` for the actual inference logic, particularly:
-- How the Wan model is initialized
-- How audio conditioning works
-- How frames are generated
-- How the final video is assembled
-
-#### 2. Update `utils/model_loader.py`
-The `load_wan_model()` method currently has a placeholder. Replace it with actual Wan model loading:
-
-```python
-def load_wan_model(self, size="infinitetalk-480", device="cuda"):
-    # Replace the placeholder with actual Wan model initialization
-    # Reference: temp-infinitetalk/generate_infinitetalk.py lines ~200-300
-    pass
-```
-
-#### 3. Integrate Inference in `app.py`
-In the `generate_video()` function around line 170, replace the placeholder section with:
-
-```python
-# Current placeholder (line ~230):
-raise gr.Error("Video generation logic needs to be integrated...")
-
-# Replace with actual inference code from generate_infinitetalk.py
-# Key steps:
-# 1. Load/prepare input frames
-# 2. Extract and process audio features
-# 3. Run diffusion model with audio conditioning
-# 4. Post-process and save video
-```
-
-#### 4. Audio Feature Extraction
-Ensure the audio feature extraction matches InfiniteTalk's requirements:
-- Check if Wav2Vec2 preprocessing is correct
-- Verify audio normalization parameters
-- Confirm sample rate (16kHz)
-
-#### 5. Video Assembly
-Implement the video assembly logic:
-- Frame generation loop
-- Streaming/chunking for long videos
-- FFmpeg video encoding
-- Audio merging
+# InfiniteTalk Space - Implementation Complete! ✅
+
+## Status: READY TO TEST
+
+The inference logic has been fully integrated! The Space now includes:
+
+### ✅ Completed Integration:
+
+1. **✅ InfiniteTalkPipeline Loading** ([utils/model_loader.py](utils/model_loader.py:107))
+   - Properly initializes `wan.InfiniteTalkPipeline`
+   - Downloads models from HuggingFace Hub
+   - Configures for single-GPU ZeroGPU environment
+
+2. **✅ Audio Processing** ([app.py](app.py:81))
+   - `loudness_norm()` function for audio normalization
+   - `process_audio()` matches reference implementation
+   - Proper 16kHz resampling
+
+3. **✅ Audio Embedding Extraction** ([app.py](app.py:218))
+   - Wav2Vec2 feature extraction
+   - Hidden state stacking
+   - Correct tensor reshaping with einops
+
+4. **✅ Video Generation** ([app.py](app.py:267))
+   - Calls `generate_infinitetalk()` with proper parameters
+   - Handles both image-to-video and video dubbing
+   - Uses `save_video_ffmpeg()` for output
+
+5. **✅ Memory Management**
+   - GPU cleanup after generation
+   - ZeroGPU duration calculation
+   - Memory monitoring
