Quick Start

For Gradio Interface (Recommended):

1. Open Video_Subtitle_Remover_Gradio.ipynb in Colab
2. Runtime → Change runtime type → GPU
3. Run all cells (Ctrl+F9)
4. Click the gradio.live URL
5. Upload video and click "Remove Subtitles"

For Traditional Notebook:

1. Open Video_Subtitle_Remover.ipynb in Colab
2. Runtime → Change runtime type → GPU
3. Run cells step by step
4. Configure settings in Step 5
5. Run processing in Step 7

Algorithm Recommendations

Use Case	Algorithm	Quality	Speed
Best Quality	DiffuEraser	⭐⭐⭐⭐⭐	⭐⭐
Fastest	STTN	⭐⭐⭐	⭐⭐⭐⭐⭐
Balanced	Stable Diffusion	⭐⭐⭐⭐	⭐⭐⭐
High Motion	ProPainter	⭐⭐⭐⭐⭐	⭐

System Requirements

• GPU: Required (T4/P100/V100)
• Storage: 10-20GB for models
• VRAM:
  • STTN: 4GB
  • DiffuEraser: 12GB
  • Stable Diffusion: 8GB

Performance (Colab T4 GPU)

Video	Algorithm	Time
1 min 720p	STTN	~30s
1 min 720p	DiffuEraser	~3-5min
5 min 720p	STTN	~2min
5 min 720p	DiffuEraser	~15-20min

Troubleshooting

Gradio not loading

• Wait 30-60 seconds for models to load
• Check if all cells ran successfully
• Restart runtime and try again

Out of Memory

• Reduce batch size in settings
• Use STTN instead of DiffuEraser
• Process shorter videos

Slow processing

• Use STTN for preview
• Enable GPU in Colab settings
• Consider Colab Pro for unlimited runtime

Tips

1. Start with STTN to test quickly
2. Use DiffuEraser for final high-quality output
3. Keep videos under 10 minutes on free tier
4. Save to Google Drive to avoid data loss
5. Monitor GPU usage with !nvidia-smi
