Your task is to create a perfectly structured, verbatim transcript of a video. # Objective Produce a single, cohesive output containing the parts in this order: 1. A Video Title 2. A **Table of Contents (ToC)** 3. The **full, chapter-segmented transcript** * Use the same language as the transcription for the Title and ToC. # Critical Instructions ## 1. Transcription Fidelity: Verbatim & Untranslated * Transcribe every spoken word exactly as you hear it, including filler words (`um`, `uh`, `like`) and stutters. * **NEVER translate.** If the audio is in Chinese, transcribe in Chinese. If it mixes languages (e.g., "这个 feature 很酷"), your transcript must replicate that mix exactly. ## 2. Speaker Identification * **Priority 1: Use metadata.** Analyze the video's title and description first to identify and match speaker names. * **Priority 2: Use audio content.** If names are not in the metadata, listen for introductions or how speakers address each other. * **Fallback:** If a name remains unknown, use a generic but consistent label (`**Speaker 1:**`, `**Host:**`, etc.). * **Consistency is key:** If a speaker's name is revealed later, you must go back and update all previous labels for that speaker. ## 3. Chapter Generation Strategy * **For YouTube Links:** First, check if the video description contains a list of chapters. If so, use that as the primary basis for segmenting the transcript. * **For all other videos (or if no chapters exist on YouTube):** Create chapters based on significant shifts in topic or conversation flow. ## 4. Output Structure & Formatting * **Timestamp Format** * All timestamps throughout the entire output MUST use the exact `[HH:MM:SS]` format (e.g., `[00:01:23]`). Milliseconds are forbidden. * **Table of Contents (ToC)** * Must be the very first thing in your output, under a `## Table of Contents` heading. * Format for each entry: `* [HH:MM:SS] Chapter Title` * **Chapters** * Start each chapter with a heading in this format: `## [HH:MM:SS] Chapter Title` * Use two blank lines to separate the end of one chapter from the heading of the next. * **Dialogue Paragraphs (VERY IMPORTANT)** * **Speaker Turns:** The first paragraph of a speaker's turn must begin with `**Speaker Name:** `. * **Paragraph Splitting:** For a long continuous block of speech from a single speaker, split it into smaller, logical paragraphs (roughly 2-4 sentences). Separate these paragraphs with a single blank line. Subsequent consecutive paragraphs from the *same speaker* should NOT repeat the `**Speaker Name:** ` label. * **Timestamp Rule:** Every single paragraph MUST end with exactly one timestamp. The timestamp must be placed at the very end of the paragraph's text. * ❌ **WRONG:** `**Host:** Welcome back. [00:00:01] Today we have a guest. [00:00:02]` * ❌ **WRONG:** `**Jane Doe:** The study is complex. We tracked two groups over five years to see the effects. [00:00:18] And the results were surprising.` * ✅ **CORRECT:** `**Host:** Welcome back. Today we have a guest. [00:00:02]` * ✅ **CORRECT (for a long monologue):** `**Jane Doe:** The study is complex. We tracked two groups over a five-year period to see the long-term effects. [00:00:18] And the results, well, they were quite surprising to the entire team. [00:00:22]` * **Non-Speech Audio** * Describe significant sounds like `[Laughter]` or `[Music starts]`, each on its own line with its own timestamp: `[Event description] [HH:MM:SS]` --- ### Example of Correct Output ## Table of Contents * [00:00:00] Introduction and Welcome * [00:00:12] Overview of the New Research ## [00:00:00] Introduction and Welcome **Host:** Welcome back to the show. Today, we have a, uh, very special guest, Jane Doe. [00:00:01] **Jane Doe:** Thank you for having me. I'm excited to be here and discuss the findings. [00:00:05] ## [00:00:12] Overview of the New Research **Host:** So, Jane, before we get into the nitty-gritty, could you, you know, give us a brief overview for our audience? [00:00:14] **Jane Doe:** Of course. The study focuses on the long-term effects of specific dietary changes. It's a bit complicated but essentially we tracked two large groups over a five-year period. [00:00:21] The first group followed the new regimen, while the second group, our control, maintained a traditional diet. This allowed us to isolate variables effectively. [00:00:28] [Laughter] [00:00:29] **Host:** Fascinating. And what did you find? [00:00:31] --- Begin transcription now. Adhere to all rules with absolute precision.
