✨ AI VFX: A New Era

Visual effects (VFX) that once required entire teams, expensive software, and weeks of work can now be created by one person in minutes using AI. In 2026, independent creators have access to capabilities that rivaled Hollywood studios just a few years ago.

What changed in VFX with AI

  • • Background removal: From 30 minutes manually to 3 seconds automatically
  • • Rotoscoping: AI automatically separates elements frame by frame
  • • Color grading: Complex color adjustments with a text prompt
  • • Scene generation: Create entire scenes that don't exist

AI VFX Tools in 2026

🟢 Background Removal (AI Green Screen)

Background removal is the most commonly used effect in video production. With AI, you no longer need a physical green screen—the artificial intelligence identifies and removes the background automatically.

Background removal in CapCut

  1. Import the video into the timeline
  2. Select the clip and go to Tools > Remove Background
  3. Choose the mode: Auto (AI detects the person) or Chroma Key (green screen)
  4. Adjust the sensitivity if needed
  5. Add a new background: image, video, or solid color

Tips for better results

  • • Record with good, even lighting (fewer shadows = better cutout)
  • • Avoid clothing colors that are too similar to the background
  • • For curly/coily hair, slightly increase the sensitivity
  • • If possible, use a plain background (even without a green screen)

🖼️ Setting Replacement

After removing the background, you can replace it with any setting. Combine it with AI-generated images to create impossible settings.

Usage examples

Product video

Film the product on a simple table, remove the background, and add a sophisticated scene generated by Midjourney.

Corporate presentation

Record at home and replace the background with a modern office or slides from your presentation.

Educational content

Place yourself in settings related to the topic: space, underwater, laboratory.

Virtual Travel

Use photos of tourist destinations as backgrounds to create travel content without leaving home.

Powerful combination: Midjourney + CapCut

Generate a scene in Midjourney with the prompt: "modern minimalist studio background, soft lighting, 16:9 --ar 16:9 --v 7". Use this image as a background in CapCut after removing the background from your video. Professional results in 5 minutes.

🎯 Basic Motion Tracking

Motion tracking lets you attach text, images, or effects to a moving object in the video. AI analyzes the movement frame by frame and keeps the element fixed at the correct point.

Common uses of motion tracking

  • Price based on product: Pin a price tag that follows the product as it moves
  • Directional arrow: An arrow pointing to a specific detail in motion
  • Censorship/Blur: Blur that follows a face or license plate
  • Floating text: Name/title that follows a person walking

Motion tracking in CapCut

  1. Add the element (text, image, sticker) over the video on the timeline
  2. Select the element and click Track Movement
  3. In the preview, position the tracking point on the desired object
  4. Click Start Tracking
  5. AI analyzes the movement and links the element to the object
  6. Adjust the position and scale if needed

🎨 AI Color Grading

Color grading (color correction and styling) is what turns an amateur video into a professional one. With AI, you can apply complex cinematic looks with one click or a text prompt.

Color grading in CapCut

  1. Select the clip on the timeline
  2. Go to Settings > Color
  3. Use AI Color for automatic color correction
  4. Explore the LUTs (Look-Up Tables) presets
  5. Manually adjust: brightness, contrast, saturation, temperature
  6. For consistency, copy the settings and paste them into all clips

Popular color grading styles

Style Features Ideal for
Cinematic Warm tones, blue shadows, high contrast Stories, trailers
Clean/Bright Vivid colors, high brightness, low contrast Products, lifestyle
Moody/Dark Dark tones, desaturated, strong shadows Fashion, drama
Vintage/Film Yellowish tones, grain, lifted blacks Nostalgia, vlogs

🛠️ Hands-On Project: VFX in a Product Video

We'll apply everything we've learned in a hands-on project: creating a product video with professional visual effects.

Step-by-step project guide

  1. Record the product: Film an object on a table with good lighting (you can use a phone)
  2. Remove the background: Use CapCut to remove the background automatically
  3. Generate a scene: Create a premium background in Midjourney or FLUX
  4. Replace the setting: Set the generated scene as the background in CapCut
  5. Add motion tracking: Pin a price or product name label that follows the object
  6. Apply color grading: Use the Clean/Bright style to make the product stand out
  7. Add a Pika effect: Create a short version with a creative effect for TikTok (optional)
  8. Finalize: Add text, transitions, and background music

Expected result

A 15-30 second video showing a product in a premium setting, with animated text, professional colors, and at least one AI effect. This type of video is exactly what brands pay hundreds (or thousands) of reais to produce.
