Click the **Color Grading Assistant** conversation starter
#### Step 2: Export a Frame
**Method 1:** [**Frame Export Button** ](/getting-started/interface-overview/frame-capture-button.md)**(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](/getting-started/interface-overview/frame-capture-button.md) 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 *** **Next:** Learn about the [Video Prompter Assistant](/conversation-starters/video-prompter-assistant.md) for structured prompt creation. --- # Agent Instructions This documentation is published with GitBook.
