  }'
```

### 9. Trim to Social Media Length

Optimize videos for specific social media platform requirements.

```bash
# Instagram Reels / TikTok (15 seconds)
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 exactly 15 seconds for Instagram Reels. Pick the most engaging 15-second segment."}],
    "model": "eachsense/beta",
    "stream": true,
    "mode": "max",
    "video_urls": ["https://example.com/content.mp4"]
  }'

# YouTube Shorts (30 seconds)
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 30-second clip optimized for YouTube Shorts from this video. Focus on the hook at the start."}],
    "model": "eachsense/beta",
    "stream": true,
    "mode": "max",
    "video_urls": ["https://example.com/content.mp4"]
  }'

# Standard social clip (60 seconds)
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 to 60 seconds maximum for Twitter/X. Keep the most important content."}],
    "model": "eachsense/beta",
    "stream": true,
    "mode": "max",
    "video_urls": ["https://example.com/content.mp4"]
  }'
```

### 10. Loop-Friendly Trim

Create seamlessly looping video clips for social media.

```bash
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 create a seamless loop. Find a segment where the end flows naturally back to the beginning, ideally 5-10 seconds long for a satisfying social media loop."}],
    "model": "eachsense/beta",
    "stream": true,
    "mode": "max",
    "video_urls": ["https://example.com/loopable-content.mp4"]
  }'
```

## 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

| Platform | Recommended Length | Notes |
|----------|-------------------|-------|
| TikTok | 15-60 seconds | Hook in first 3 seconds |
| Instagram Reels | 15-30 seconds | 90 seconds max |
| YouTube Shorts | 30-60 seconds | Under 60 seconds required |
| Twitter/X | 30-60 seconds | 2:20 max for standard accounts |
| LinkedIn | 30-90 seconds | Professional context |

## 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?"**

| Mode | Best For | Speed | Quality |
|------|----------|-------|---------|
| `max` | Final exports, client deliverables, quality-critical | Slower | Highest |
| `eco` | Quick previews, batch processing, draft iterations | Faster | Good |

## Multi-Turn Editing Session

Use `session_id` to iterate on video edits:

```bash
# 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"
  }'
```

## Error Handling

| Error | Cause | Solution |
|-------|-------|----------|
| `Failed to create prediction: HTTP 422` | Insufficient balance | Top up at eachlabs.ai |
| Timeout | Long video processing | Set client timeout to minimum 10 minutes |
| Invalid timestamp | Timestamp exceeds video length | Verify video duration first |
| Unsupported format | Video codec not supported | Convert to MP4/H.264 first |
