Pipeline Overview

WTN Suite works with two different versions of your artwork, and understanding the difference is the key to understanding the whole pipeline:

• Page — output of Webtoon Cropper. Still has text bubbles and dialogue intact. The AI reads pages, because it needs that dialogue for context when writing narration.
• Panel — a clean, text-free crop, produced automatically. This is what actually appears in your final video — the on-screen text is gone because the narration audio replaces it.

One manual step (Webtoon Cropper) turns your raw download into pages. From there, one click — Analyze & Narrate — runs three AI stages automatically: automatic panel cropping, scene analysis, and narrative writing.

How It Works

Your workflow:

Step	What You Do
Step 1	Run Webtoon Cropper on your downloaded scroll — produces pages
Step 2	Click "Load Chapter & Review Panels" — loads your pages into the grid
Step 3	Click "Analyze & Narrate" — AI crops clean panels, analyzes every page, and writes the narration

What happens automatically when you click Analyze & Narrate:

Stage	What It Does	Time Estimate
Panel Cropping	Crops each page down into a clean, text-free panel for video export	~30 sec per page
Scene Analysis	AI reads each page — dialogue included — for characters, actions, mood	~5 sec per page
Narrative Writing	AI writes a narration script for the entire chapter	~30 sec total

After the pipeline finishes, you export the narration to audio (using Edge-TTS or Kokoro-TTS), then create a video with the Video Compositor using the clean panels.

Before You Start

Make sure you have:

• Webtoon pages ready — download the chapter with WT-Downloader, then split the scroll into pages with Webtoon Cropper (required — the pipeline can't load a raw continuous scroll directly)
• An AI API key configured in Settings

---

Step 1: Crop Into Pages

Before anything else, run your downloaded chapter through Webtoon Cropper. This is the one manual step in the pipeline — WTN Suite needs pages, not a raw continuous scroll, to work with.

Place your cut lines at natural scene breaks. Where you cut matters: a clean cut gives the AI a self-contained page to read, while cutting mid-dialogue can split a character's speech across two pages and hurt narration quality later.

---

Step 2: Load Your Pages

Click "Load Chapter & Review Panels" on the toolbar and select the pages you just exported from Webtoon Cropper.

This step just loads your pages into the main grid — no AI runs yet. Each row shows:

• A preview of the page image
• Character list (initially "Awaiting Analysis")
• Narrative text (initially "Awaiting Narration")
• Status indicator

---

Step 3: Analyze & Narrate

Click "Analyze & Narrate" to kick off all three automatic AI stages.

Automatic Panel Cropping

WTN Suite crops each page down into a clean, text-free panel — this is what will show up in your final video. It handles this differently depending on your content:

Mode	Best For	Set In
Manhwa Style	Korean webtoons (vertical scroll, clear panel borders)	Settings → Panel Detection Model
Manhua Style	Manga and manhua (page layouts with complex arrangements)	Settings → Panel Detection Model

Scene Analysis

The AI reads each page — dialogue and text bubbles included — and describes what's happening: characters present, their actions, emotions, the setting, and visual details. This analysis feeds into the Narrative Writing stage, and it's only possible because pages keep their text; a clean panel alone wouldn't give the AI enough to work with.

What the AI identifies in each page:

• Characters and their names (auto-detected)
• Actions and movements
• Emotions and expressions
• Scene setting and background
• Important visual details (text bubbles, effects)

Narrative Writing

Narrative Writing runs automatically after Scene Analysis finishes. The AI takes all the scene analysis results and writes a continuous narration script — a story that flows from page to page with smooth transitions.

Narrator Prompt Templates

You can choose how the AI writes the narration by selecting a template in Settings:

Template	Style
Master Prompt v4.1	Cinematic storytelling with continuity rules — works best for most content
Template 2 v4	Choose between Pure Narration, Character Interaction, Visuals Only, or Mixed styles
Template 3 v3	Simplified version of Template 2 — faster processing
Khmer Language	Narration in Cambodian/Khmer
Custom Prompt	Write your own instructions for full control

Reviewing and Editing Results

After the pipeline finishes, review the results in the main grid:

• Edit narration: Click "Edit" next to any row's narrative text to modify it directly
• Re-run a single page: Click "Rerun AI" next to a specific page to regenerate its analysis and narration
• Export panels: Click "Export Panels" to save the clean, cropped panel images to a folder — this is what the Video Compositor uses
• Export narration: Click "Export Narration" to save all narrative text as a TXT file

---

Next Steps

Once you're happy with the narration:

1. Generate audio — Use Edge-TTS (all plans) or Kokoro-TTS (Standard/Pro) to convert text to speech
2. Create video — Use the Video Compositor to combine the clean panels + audio into a final video
3. Advanced editing — Export to CapCut Director (Standard/Pro) for animations and subtitles
4. Refine characters — Optionally use the Character Builder if you want to assign specific names to auto-detected characters
