Sci-Fi: Symmetric Constraint for Frame Inbetweening

Generate smooth frame interpolation videos using CogVideoX-5B with EF-Net.

Features

• 🎬 High-quality frame inbetweening
• ⚡ GPU-accelerated inference with Spaces GPU
• 🎨 Customizable generation parameters
• 📊 Real-time progress tracking

Usage

1. Setup Tab: Load the model pipeline (required first step)
2. Generate Tab: Upload start and end frames, enter a prompt
3. Advanced Settings: Fine-tune generation parameters

Model Details

• Base Model: CogVideoX-5B-I2V
• EF-Net: Custom enhancement network for symmetric frame constraints
• Output: 49 frames at 7 FPS (720x480)
