### What It Does

The Color Grade Assistant:

* **Analyzes footage** using technical scope data (luminance, color cast, saturation)
* **Provides Lumetri corrections** with one-click application
* **Generates custom LUT files** (.cube format) for creative looks
* **Matches reference images** with style transfer
* **Protects skin tones** while applying creative grades
* **Emulates film stocks** (Kodak, Fuji, CineStill, etc.)

### How to Use

#### Step 1: Start the Assistant

1. Click the **Color Grading Assistant** conversation starter

**Method 1:** [**Frame Export Button** ](https://docs.chatvideopro.com/getting-started/interface-overview/frame-capture-button)**(Recommended)**

1. In Premiere Pro, position your playhead on the clip you want to grade
2. Click the **Frame Export button** (📷) in Chat Video Pro composer
3. The frame appears as an attachment

**Method 2: Upload Screenshot**

1. Take a screenshot of your footage in Premiere Pro
2. Drag & drop or upload the image file
3. Ensure it's a high-quality capture (not compressed)

#### Step 3: Get Technical Analysis

Ask one of these:

* "What's wrong with this shot?"
* "Analyze the color."
* "How can I improve this?"
* "What corrections does this need?"

**You'll receive:**

* **Technical score** (0-100) based on exposure, color balance, and saturation
* **Specific issues** identified (underexposed, color cast, crushed shadows, etc.)
* **Lumetri recommendations**
* **One-click Apply button** to apply corrections directly
* **Custom LUT file** created for your footage if needed

Example analysis:

#### Step 4: Apply Corrections

**Option A: One-Click Apply**

1. Review the recommendations
2. Click the **"Apply to current clip"** button
3. Corrections are applied directly to your Premiere Pro clip
4. Adjust intensity in the Lumetri panel if needed

#### Step 5: Request Creative Look (Optional)

Ask for a specific style:

* "Create a cinematic LUT."
* "Give me a Blade Runner look."
* "Make it look like film noir."
* "Vintage 16mm film look"
* "Teal and orange grade"

**You'll receive:**

* **Downloadable .cube LUT file**
* **Explanation** of the look created
* **Instructions** for applying in Premiere Pro

### Style Transfer (Match Reference)

Match the color grade from a reference image to your footage.

#### Steps

1. **Upload Two Images**
   * **Source** (purple border): Your footage to be graded
   * **Reference** (green border): The look you want to match
2. **Use the Swap Button** (if needed)
   * Click the ↔ button to switch source and reference positions
3. **Request Style Transfer**
   * Type: "Match the colors" or "Apply this look to my footage"
   * The AI analyzes both images and generates a matching LUT
4. **Download and Apply**
   * Download the `.cube` LUT file
   * Apply in Premiere: Lumetri → Creative → Look → Browse

### LUT Generation

#### Available Looks

The Color Grade Assistant can create infinite LUTs for any style. Here are some ideas:

**Cinematic Styles:**

* Blade Runner (teal shadows, warm highlights)
* Film Noir (high contrast, desaturated)
* Golden Hour (warm, soft, glowing)
* Cinematic (S-curve, teal & orange)

**Film Stock Emulation:**

* Kodak Vision3 500T
* Fuji Eterna 500
* CineStill 800T
* Kodak Portra 400
* Ilford HP5 (black & white)

**Creative Looks:**

* Vintage 16mm
* Horror/Thriller
* Documentary Natural
* Commercial Vibrant
* Desaturated Muted

#### How to Request a LUT

Be specific:

* ✅ "Create a cinematic LUT with teal shadows and warm highlights."
* ✅ "Give me a Blade Runner look."
* ✅ "Make a LUT that looks like Kodak Vision3."
* ✅ "Vintage film look with heavy grain simulation."

Less effective:

* ❌ "Make it better" (too vague)
* ❌ "Fix the colors" (use technical correction instead)

### Skin Tone Protection

When grading footage with people, the Color Grade Assistant automatically enables skin tone protection.

#### Requesting Specific Levels

* **"Heavy skin protection"** (0.7-0.85) - For close-ups, portraits
* **"Subtle skin protection"** (0.3-0.5) - For wide shots with people
* **"No skin protection"** (0) - For scenes without people, full creative freedom

#### How It Works

Skin tone protection:

* **Preserves natural skin colors** while applying creative grades
* **Adjustable intensity** based on your needs
* **Automatic detection** when people are in the frame

### Technical Analysis Details

The Color Grade Assistant uses real scope data, not visual guessing:

#### What Gets Analyzed

1. **Luminance Distribution**
   * Average brightness
   * Shadow/highlight clipping percentages
   * Tonal range assessment
2. **Color Cast Detection**
   * Warm/Cool bias
   * Green/Magenta tint
   * Neutral assessment
3. **Saturation Levels**
   * Overall saturation
   * Zone-specific saturation
   * Vibrancy assessment
4. **Exposure Assessment**
   * Underexposed/overexposed detection
   * Safe exposure range
   * Recovery recommendations

#### Score Interpretation

* **90-100:** Technically excellent, minimal corrections needed
* **70-89:** Moderate corrections recommended
* **50-69:** Significant corrections needed
* **Below 50:** Major issues, extensive correction required

### Applying LUTs in Premiere Pro

#### Method 1: Lumetri Creative Tab

1. Select your clip in Premiere Pro
2. Open the **Lumetri Color** panel
3. Go to **Creative → Look**
4. Click **Browse** next to "Look."
5. Select your downloaded `.cube` file
6. Adjust **Intensity** slider (0-200%) to taste

#### Method 2: Lumetri Effect

1. Apply **Lumetri Color** effect to your clip
2. In the Effect Controls panel
3. Go to **Creative → Look**
4. Browse and select your `.cube` file
5. Adjust intensity

### Tips for Best Results

1. **Export high-quality frames** - Use [the Frame Export button](https://docs.chatvideopro.com/getting-started/interface-overview/frame-capture-button) for best accuracy
2. **Convert Log to Rec.709 first** - If working with Log footage, normalize before grading
3. **Apply Lumetri effect** - Ensure clip has Lumetri Color effect applied
4. **Be specific** - "Cinematic" is better than "make it look good."
5. **Iterate** - Ask for adjustments: "Make it warmer" or "More contrast."
6. **Combine corrections** - Apply technical fixes first, then creative LUT

### Common Workflows

#### Workflow 1: Technical Correction → Creative Grade

1. Export frame → Get analysis → Apply corrections
2. Ask for creative LUT → Download → Apply on top
3. Result: Technically correct + stylistically graded

#### Workflow 2: Style Transfer

1. Upload source + reference images
2. Request style transfer
3. Download matching LUT
4. Apply to the entire sequence

#### Workflow 3: Film Stock Emulation

1. Export frame
2. Request: "Make it look like Kodak Vision3."
3. Download film stock LUT
4. Apply and adjust intensity

### Troubleshooting

#### "Apply button doesn't appear."

* Ensure you're inthe Color Grading Assistant conversation
* Check that the frame is uploaded
* Verify the Lumetri Color effect is applied to the clip in Premiere

#### "LUT looks too strong/weak."

* Adjust **Intensity** slider in Lumetri (0-200%)
* Request a lighter/heavier version: "Make it more subtle."
* Combine with basic corrections for balance

#### "Analysis seems inaccurate."

* Use the Frame Export button (not screenshots) for best results
* Ensure the frame represents the clip accurately
* Check that the clip isn't already heavily graded
