Mode Selection

Ask your users before converting:

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

Mode	Best For	Speed	Quality
`max`	Final deliverables, ProRes, professional workflows	Slower	Highest
`eco`	Quick previews, batch processing, draft conversions	Faster	Good

Multi-Turn Conversion Session

Use session_id to maintain context for iterative conversions:

# Initial conversion
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": "Convert this video to MP4 for YouTube at 1080p"}],
    "model": "eachsense/beta",
    "stream": true,
    "session_id": "youtube-upload-project",
    "image_urls": ["https://example.com/raw-footage.mov"]
  }'

# Request different format from same source
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": "Now create a vertical version of that same video for YouTube Shorts at 9:16"}],
    "model": "eachsense/beta",
    "stream": true,
    "session_id": "youtube-upload-project"
  }'

# Request thumbnail extraction
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": "Extract a thumbnail from the best frame of that video"}],
    "model": "eachsense/beta",
    "stream": true,
    "session_id": "youtube-upload-project"
  }'

Platform-Specific Settings

Bitrate: 8-12 Mbps for 1080p, 35-45 Mbps for 4K

Instagram Reels / TikTok

Format: MP4 (H.264)
Aspect ratio: 9:16
Resolution: 1080x1920
Duration: Under 60 seconds (Reels) / 3 minutes (TikTok)
File size: Under 100MB

Twitter/X

Format: MP4 (H.264)
Aspect ratio: 16:9, 1:1, or 9:16
Resolution: Up to 1920x1200
Duration: Up to 2:20 (140 seconds)
File size: Under 512MB

Format: MP4 (H.264)
Aspect ratio: 16:9 or 1:1
Resolution: 1080p maximum
Duration: 10 minutes maximum

Error Handling

Error	Cause	Solution
`Failed to create prediction: HTTP 422`	Insufficient balance	Top up at eachlabs.ai
Timeout	Large video file or complex conversion	Set client timeout to minimum 10 minutes
Unsupported format	Source format not recognized	Convert to intermediate format first
File too large	Video exceeds size limits	Compress or split video before conversion

Best Practices

Quality

Use max mode for final deliverables and professional outputs
Use eco mode for previews and batch processing
Specify target bitrate for predictable file sizes
Request 2-pass encoding for better quality at lower bitrates

Performance

Set client timeout to minimum 10 minutes for video processing
Use eco mode for faster turnaround on large batches
Process shorter clips when testing settings

Compatibility

H.264 is the most universally compatible codec
WebM/VP9 offers better compression but less device support
ProRes is ideal for editing workflows but creates large files
Always test output on target devices/platforms
