Best Practices

Color Grading Tips

Reference Images: Describe a specific film or visual reference for consistent results
Be Specific: Mention shadow color, highlight warmth, contrast level, saturation
Skin Tones: Always mention if preserving natural skin tones is important
Mood First: Start with the emotion/mood you want, then technical details

Technical Considerations

Source Quality: Better source footage yields better grading results
Consistency: Use
```
session_id
```
to grade multiple clips with the same look
Preview First: Use
```
eco
```
mode for quick previews,
```
max
```
for final output

Common Terminology

Term	Description
Lift	Adjusts shadow brightness
Gamma	Adjusts midtone brightness
Gain	Adjusts highlight brightness
Crush	Deepening blacks beyond pure black
Push	Adding color tint to a tonal range
Color Cast	Unwanted color tint across image

Mode Selection

Ask your users before generating:

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

Mode	Best For	Speed	Quality
`max`	Final deliverables, client work	Slower	Highest
`eco`	Quick previews, look exploration, drafts	Faster	Good

Multi-Turn Creative Iteration

Use

session_id

to iterate on color grades:

bash

# Initial grade
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": "Apply a cinematic teal and orange grade to this video",
    "session_id": "color-grade-project-001",
    "video_urls": ["https://example.com/my-video.mp4"]
  }'

# Refine the grade
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 teal is too strong in the shadows. Can you reduce it and add more warmth to the skin tones?",
    "session_id": "color-grade-project-001"
  }'

# Apply to additional clips
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": "Apply the same grade we developed to this new clip",
    "session_id": "color-grade-project-001",
    "video_urls": ["https://example.com/second-clip.mp4"]
  }'

Batch Color Grading

Grade multiple clips with the same look:

bash

# Grade first clip and establish look
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": "Apply a moody cinematic grade to this video - this will be my hero look for the project",
    "session_id": "music-video-grade",
    "video_urls": ["https://example.com/clip-01.mp4"]
  }'

# Apply same look to remaining clips
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": "Apply the same color grade to these additional clips for consistency",
    "session_id": "music-video-grade",
    "video_urls": [
      "https://example.com/clip-02.mp4",
      "https://example.com/clip-03.mp4",
      "https://example.com/clip-04.mp4"
    ]
  }'

Error Handling

Error	Cause	Solution
`Failed to create prediction: HTTP 422`	Insufficient balance	Top up at eachlabs.ai
Content policy violation	Prohibited content	Ensure video complies with content policies
Timeout	Complex video processing	Set client timeout to minimum 10 minutes
Video too long	Exceeds processing limits	Split video into shorter segments

Prompt Tips for Color Grading

When requesting color grades, include these details:

Reference: Film, director, or visual style reference
Mood: The emotional tone (moody, bright, dramatic, soft)
Shadow Treatment: Color and depth (crushed, lifted, tinted)
Highlight Treatment: Warmth, rolloff, color
