Multi-Turn Workflow Example

Use session_id to iterate on background replacements across multiple requests.

# Initial background removal
curl -X POST https://sense.eachlabs.run/chat \
  -H "Content-Type: application/json" \
  -H "X-API-Key: $EACHLABS_API_KEY" \
  -H "Accept: text/event-stream" \
  -d '{
    "message": "Remove the background from this video of me presenting",
    "session_id": "bg-removal-project-001",
    "video_urls": ["https://example.com/presentation.mp4"]
  }'

# Iterate with different background
curl -X POST https://sense.eachlabs.run/chat \
  -H "Content-Type: application/json" \
  -H "X-API-Key: $EACHLABS_API_KEY" \
  -H "Accept: text/event-stream" \
  -d '{
    "message": "Now replace it with a modern tech office background instead",
    "session_id": "bg-removal-project-001"
  }'

# Fine-tune the result
curl -X POST https://sense.eachlabs.run/chat \
  -H "Content-Type: application/json" \
  -H "X-API-Key: $EACHLABS_API_KEY" \
  -H "Accept: text/event-stream" \
  -d '{
    "message": "The edges look a bit rough around my hair. Can you refine the matte for better edge quality?",
    "session_id": "bg-removal-project-001"
  }'

Mode Selection

Choose the appropriate mode based on your needs:

Recommendation: Use eco mode for testing backgrounds and max mode for final renders.

Best Practices

For Clean Extractions

• Lighting: Well-lit subjects extract better than low-light footage
• Contrast: Higher contrast between subject and background helps
• Movement: Slower movements produce cleaner mattes
• Hair/Fine Details: Request “refined edges” for subjects with complex hair

For Natural Composites

• Lighting Match: Request backgrounds that match your footage lighting
• Color Grading: Ask for color matching between subject and background
• Shadows: Request natural shadow placement for grounded composites
• Depth of Field: Match background blur to your camera’s depth of field

For Professional Results

• Specify your use case (corporate, social media, broadcast)
• Mention output requirements (resolution, format)
• Request specific background styles that match your brand

Prompt Tips

When requesting background removal/replacement, include:

1. Source Description: What’s in your video (person, product, etc.)
2. Background Goal: Transparent, solid color, specific scene, blur
3. Quality Requirements: Edge quality, shadow handling, reflections
4. Use Case: Where will this video be used
5. Style Matching: Lighting, color tone, atmosphere

Example Prompt Structure

"Remove/replace the background from this [subject type] video.
[New background description or transparent/solid color].
[Edge quality and compositing requirements].
For use in [context/platform]."

Error Handling

Timeout Configuration

Video background removal is computationally intensive. Configure your HTTP client with adequate timeout:

• Minimum recommended timeout: 10 minutes (600 seconds)
• For longer videos: Increase proportionally (1 minute timeout per 10 seconds of video)

# Example with explicit timeout using curl
curl --max-time 600 -X POST https://sense.eachlabs.run/chat \
  -H "Content-Type: application/json" \
  -H "X-API-Key: $EACHLABS_API_KEY" \
  -H "Accept: text/event-stream" \
  -d '{
    "message": "Remove background from this video",
    "mode": "max",
    "video_urls": ["https://example.com/long-video.mp4"]
  }'
