Transform static images into vivid video animations with WAN 2.1 I2V Start/End Frame Workflow, enabling precise control over both starting and ending frames. This powerful method provides frame-anchored interpolation, ideal for storytelling, cinematic transitions, and animated scenes that maintain style, structure, and character integrity.

🎯 Features

• Start & End Frame Anchoring – Define the beginning and end visuals to guide the motion transformation.
• WAN 2.1 Integration – Leverages the strength of the WAN FUN model series for high-quality interpolation.
• Style-Coherent Transitions – Ensures visual and stylistic consistency between frames.
• Frame Count Control – Adjust the number of interpolated frames for pacing and duration flexibility.
• Built for ComfyUI – Entirely within ComfyUI with labeled, modular, and reusable nodes.

💡 Use Cases

• Image-to-Video Animation – Breathe life into static art with fluid motion between keyframes.
• Cinematic Scene Previews – Build animated cutscenes from concept art.
• Character Posing – Animate transitions between expressions or actions.
• AI Storytelling – Chain scenes using end-to-start frame logic to create coherent narrative videos.

⚙️ How It Works

1. Prepare Input Frames

   • Select your start frame image and end frame image.
   • Use Get_img_start and Get_img_end nodes to feed them into the workflow.

2. Preprocess & Encode Style

   • Optionally style both images using CLIP and img_restyle.
   • Resize if needed to match WAN input specs (typically 512–768px square).

3. Load WAN & Support Models

   • Include WAN FUN 1.3B, wan_2.1_vae.safetensors, and the appropriate CLIP and CLIP Vision loaders.

4. Interpolation via WAN

   • Set the num_frames (e.g., 20–60) to control transition length.
   • Use the WAN model's interpolation pipeline to create smooth in-between frames.

5. Postprocess with RIFE (optional)

   • Enhance fluidity with RIFE VFI interpolation if needed.

6. Output Video

   • Compile the generated frames into a video with VHS_VideoCombine.
   • Adjust FPS, filename prefix, and compression to suit your use.
