What Kling VFX Does
Kling VFX adds visual effects while:

Preserving audio - Original audio automatically maintained
Adding effects - Rain, fire, lighting, weather, atmosphere changes
Style transformation - Change lighting, time of day, weather, mood
Scene modification - Transform environments and atmospheres
Two Ways to Use Kling VFX

Method 1: Video Only
What it does:
Uses only your video and text prompt
Good for simple, straightforward effects
Faster workflow
Relies on text description alone
Use when:
Simple effects (rain, snow, basic lighting)
Quick transformations
You can describe the effect clearly in text
Example:
Video: Daytime street scene
Prompt: "Make it nighttime with dramatic street lighting"
Result: Day-to-night transformation

Method 2: Video + Reference Image (Recommended)
What it does:
Uses your video + a reference image
Shows the model exactly what you want
More powerful and accurate
Better for complex style changes
Use when:
Complex style transformations
Specific lighting/atmosphere you want
You want to show, not just describe
Maximum control over the result
How to reference the image:
Add reference image in the interface
Reference it in your prompt as
@Image1Describe how to use it: "Make the scene look like @Image1"
Example:
Video: Daytime street scene
Reference Image: Stylized nighttime scene (from Nano Banana)
Prompt: "Make the scene nighttime as shown in @Image1"
Result: Matches the reference image style
The Power Workflow: Nano Banana + Kling VFX
The most powerful way to use Kling VFX is to create a reference image first, then use it to guide the video transformation.
Step 1: Create Stylized Image with Nano Banana
What to do:
Take a frame from your video (or describe the scene)
Use Nano Banana to create a stylized version
Apply the style you want (nighttime, snowy, different lighting, etc.)
Examples:
"Make this scene nighttime with neon lights and wet streets"
"Transform this to a snowy winter scene with falling snow"
"Change the lighting to golden hour with warm tones"
"Make it foggy with atmospheric mist"
Result: A stylized image showing exactly what you want
Step 2: Use Image as Reference with Kling VFX
What to do:
Import your video
Add the Nano Banana image as reference
Reference it in your prompt as
@Image1Describe how to use it
Example prompts:
Result: Video transformed to match your reference image
Why This Works Better
Shows, don't tell - Image shows exactly what you want
More accurate - Model sees the target style
Better results - Visual reference beats text description
Complex styles - Can capture nuanced lighting/atmosphere
Writing Effect Prompts
What to Describe
Focus on the effect you want to add, not the entire scene:
Effect type - "rain", "fire", "snow", "lightning"
Location - "in the background", "on the subject", "throughout scene"
Intensity - "heavy rain", "light drizzle", "intense fire"
Lighting changes - "make it nighttime", "golden hour", "dramatic shadows"
Atmosphere - "foggy", "misty", "hazy"
Good Effect Prompts (Video Only)
✅ Weather Effects:
✅ Lighting Changes:
✅ Particle Effects:
Good Effect Prompts (With Reference Image)
✅ Using Reference Image:
Bad Effect Prompts
❌ Too Vague:
❌ Describes Entire Scene:
(Kling VFX adds to existing video, doesn't create new scene)
❌ No Effect Specified:
❌ Not Using Reference Image:
(Should reference as @Image1)
Reference Images
How to Use Reference Images
Add reference image - Click "+" button in reference image area
Upload image - Your stylized image (from Nano Banana or other source)
Reference in prompt - Use
@Image1in your promptDescribe usage - Explain how to use the reference
When to Use Reference Images
Complex style changes - Nighttime, weather, atmosphere
Specific lighting - Golden hour, dramatic shadows, mood
Visual style - Cinematic look, artistic treatment
Better accuracy - When text description isn't enough
Reference Image Guidelines
Good reference images:
Show the style/effect you want
Match the scene composition (if possible)
Clear and high quality
Represent the desired transformation
Best practices:
Create with Nano Banana for best results
Use a single, clear reference image
Ensure good quality
Match the general scene structure

Tips for Best Results
Use reference images - Show, don't just tell
Create with Nano Banana first - Best workflow for complex styles
Reference images properly - Use
@Image1in promptBe specific about effect - "Heavy rain" vs. "rain"
Describe location - "in background" vs. "everywhere"
Keep clips short - 3-10 seconds for best results
Compare results - Use Before/After toggle
Iterate if needed - Refine prompts or reference images
