Video Compositor

Create narrated videos from your webtoon panels and audio

Video Compositor

The Video Compositor combines your cropped panels and narration audio into a finished video file. It's the final step in the webtoon-to-video workflow.

Available on: All plans (some features require Standard or Pro)

When You Need It

  • You've completed the pipeline and generated audio narration
  • You want to create a video ready for YouTube, TikTok, or other platforms
  • You need a quick way to turn panels + audio into a polished video

How to Use

1

Open Video Compositor

Click "Video Compositor" on the toolbar.

2

Load Your Content

  • Load Image Folder — select the folder containing your cropped panel images
  • Load Audio Folder — select the folder containing narration audio files

The Compositor matches images and audio by filename order (001, 002, 003...).

Configure Settings

Choose your resolution, aspect ratio, and any extras (background music, watermark, intro/outro).

4

Generate Video

Click Generate Video. A progress bar shows the rendering status. The finished MP4 is saved to your output folder.

ℹ️ Info

Rendering time depends on the number of panels, resolution, and your computer's speed. A typical 40-panel chapter at 1080p takes about 3–5 minutes.

Watermark Options (Standard+)

  • Format: PNG (supports transparency)
  • Positions: Top-Right, Top-Left, Bottom-Right, Bottom-Left, Center
  • Opacity: 0% to 100%

💡 Tip

Set BGM volume to -20dB to -30dB so the narration stays clearly audible over the music. You can adjust this until it sounds right.

Output

  • Format: MP4
  • Single video — one combined file with all panels and narration
  • Individual clips (Standard+) — each panel as a separate video file, useful for further editing

Tips

💡 Tip

Keep intro/outro clips short — 3–5 seconds each is plenty for channel branding. Longer intros cause viewers to click away.

💡 Tip

Export individual clips if you want to rearrange, add effects, or do additional editing in another video editor. This gives you maximum flexibility.

💡 Tip

For more advanced editing with animations, keyframes, and subtitles, consider using the CapCut Director instead.

Common Issues

⚠️ Warning

Black frames in the video? Make sure your image and audio files are numbered in the same order. The Compositor matches them sequentially.

⚠️ Warning

Video rendering is very slow? Try reducing the resolution (use 1080p instead of 4K) or the number of panels. Closing other applications can also help free up system resources.
