🎚️ AWESOME: Add Advanced Video Export Controls!

NEW CONTROLS ADDED:
✅ Effect Intensity Slider (0.1x to 3.0x)
- Control how strong camera movements are
- 0.5x = subtle, professional
- 1.0x = balanced default
- 2.0x = dramatic, bold
- 3.0x = extreme effects!

✅ Number of Loops (1-10)
- Repeat animations seamlessly
- Perfect for longer videos

✅ Video Quality Selection
- High: 8 Mbps (best quality)
- Medium: 5 Mbps (balanced)
- Low: 3 Mbps (smaller files)

✅ Extended Duration (1-30s)
- Previously limited to 10s
- Now up to 30s per loop!

✅ More Resolution Options
- Added 4K UHD (3840x2160)
- Portrait 1080p (1080x1920)
- Portrait 720p (720x1280)
- Kept all existing options

IMPROVEMENTS:
🎬 All 14 effects now respect intensity multiplier
📊 Better progress info showing total duration and loops
📁 Improved filename with resolution and FPS
💡 Help tooltips for all new controls
📝 Updated documentation

NOW MATCHES LOCAL VERSION FEATURES!
All the power of the local Three.js version
Available on HuggingFace Spaces!
