The VFX tab allows you to enhance your rendered shots by adding visual effects, making style changes, or modifying elements within the frame. Apply everything from subtle lighting adjustments to dramatic visual transformations without regenerating the entire shot.
Plan availability: VFX (Visual Effects) is available on the Hollywood plan. Upgrade your plan to unlock VFX features.

​
What You Can Do

The VFX tab supports three levels of visual modifications:

​
Subtle Changes

  • Lighting adjustments — Change time of day, add golden hour lighting, adjust shadows
  • Color grading — Shift color palettes, increase saturation, apply color filters
  • Atmospheric effects — Add fog, rain, snow, or dust particles
  • Depth and focus — Adjust depth of field, add lens blur effects

​
Adding Elements

  • Environmental elements — Add clouds, stars, rain, snow, or other weather
  • Objects and props — Insert objects, characters, or background elements
  • Particle effects — Add sparks, smoke, magical effects, or debris
  • Lighting elements — Add light sources, lens flares, or glowing effects

​
Complete Transformations

  • Style changes — Transform entire scenes (e.g., “make it nighttime,” “add film grain”)
  • Costume/prop changes — Modify character appearance (e.g., “change her suit to yellow”)
  • Environmental overhauls — Completely change settings or add dramatic elements (e.g., “add a tentacled alien floating in the sky”)

​
Workflow

  1. Select the video generation you want to enhance from your shot gallery
  2. Enter a VFX description describing the visual effect or change you want to apply re
  3. Click Generate VFX and wait for processing to complete (typically 2-3 minutes)
  4. Review the enhanced video in the viewer
  5. If satisfied, save the result; if not, adjust your description and regenerate
VFX passes are non-destructive—you can revert to the original video at any time. Each VFX generation creates a new version without overwriting your original shot.
VFX generation uses video-to-video models. See the Video-to-Video models guide for details on available models and their capabilities.

Example VFX Prompts

Here are examples of effective VFX descriptions:
  • Time of day: “make it nighttime,” “add golden hour lighting,” “change to sunset”
  • Weather: “add heavy rain,” “make it snowing,” “add fog rolling in”
  • Style changes: “add film grain,” “make it look like a vintage photograph,” “apply a cyberpunk color palette”
  • Object modifications: “change her suit to yellow,” “add sunglasses to the character,” “replace the car with a motorcycle”
  • Environmental additions: “add a tentacled alien floating in the sky,” “add birds flying in the background,” “insert a spaceship in the distance”
  • Lighting effects: “add dramatic shadows,” “increase ambient lighting,” “add a spotlight from above”
  • Atmospheric effects: “add dust particles in the air,” “create a dreamy haze,” “add lens flares”

Tips for Best Results

  1. Be Specific — Clearly describe the visual change you want (e.g., “change suit to bright yellow” vs. “change colors”)
  2. Start Subtle — Test subtle effects first before attempting major transformations
  3. Iterate Carefully — VFX passes build on each other; review results before applying multiple effects
  4. Match Project Style — Ensure VFX effects align with your project’s overall aesthetic
  5. Use Precise Language — Specify exact colors, locations, and intensity levels when possible
💡 Tip: VFX passes are non-destructive—you can always revert to the original render if the effect doesn’t work as intended. Experiment freely!
