Best Practices

Trimming Tips

• Be specific: Provide exact timestamps (MM:SS or HH:MM:SS) when possible
• Describe content: If you do not know timestamps, describe what you want ("the part where they shake hands")
• Buffer time: Allow small buffers around cuts to avoid abrupt transitions
• Check audio: Ensure cuts do not happen mid-sentence or mid-note

Performance Optimization

• Use eco mode for batch processing or quick iterations
• Use max mode for final exports and quality-critical content
• Process shorter videos first to verify settings before batch operations

Social Media Guidelines

Prompt Tips for Video Trimming

When requesting video trims, include these details:

1. Exact timing: "from 0:45 to 1:30" or "first 30 seconds"
2. Content reference: "the interview segment" or "when the product demo starts"
3. Output requirements: "keep audio" or "I need 3 separate clips"
4. Platform target: "for Instagram Reels" or "YouTube Shorts optimized"
5. Quality preference: Use mode: "max" for finals, mode: "eco" for drafts

Example Prompt Structure

"[Action] this video [timing/selection criteria].
[Additional requirements like output format, platform, etc.]"

Examples:

• "Trim this video to 30 seconds starting at 1:00"
• "Extract three 15-second highlights from different parts of this video"
• "Remove the first 5 seconds and last 10 seconds"

Mode Selection

"Do you want fast & cheap, or high quality?"

Multi-Turn Editing Session

Use session_id to iterate on video edits:

# Initial trim
curl -X POST https://eachsense-agent.core.eachlabs.run/v1/chat/completions \
  -H "Content-Type: application/json" \
  -H "X-API-Key: $EACHLABS_API_KEY" \
  -H "Accept: text/event-stream" \
  -d '{
    "messages": [{"role": "user", "content": "Trim this video to the segment from 0:30 to 1:30"}],
    "model": "eachsense/beta",
    "stream": true,
    "session_id": "edit-session-001",
    "video_urls": ["https://example.com/raw-footage.mp4"]
  }'

# Adjust the trim
curl -X POST https://eachsense-agent.core.eachlabs.run/v1/chat/completions \
  -H "Content-Type: application/json" \
  -H "X-API-Key: $EACHLABS_API_KEY" \
  -H "Accept: text/event-stream" \
  -d '{
    "messages": [{"role": "user", "content": "Actually, extend the end by 10 more seconds to include the conclusion"}],
    "model": "eachsense/beta",
    "stream": true,
    "session_id": "edit-session-001"
  }'

# Request additional version
curl -X POST https://eachsense-agent.core.eachlabs.run/v1/chat/completions \
  -H "Content-Type: application/json" \
  -H "X-API-Key: $EACHLABS_API_KEY" \
  -H "Accept: text/event-stream" \
  -d '{
    "messages": [{"role": "user", "content": "Create a shorter 15-second version of this same segment for Instagram"}],
    "model": "eachsense/beta",
    "stream": true,
    "session_id": "edit-session-001"
  }'
