Video Downloader

Overview

Use this skill to turn a video-platform URL into a local source-material folder containing the video file, post_caption.txt, audio.wav / audio.m4a / audio.mp3, transcript.txt, transcript.srt (whisper.cpp only), and metadata.json.

Terminology:

• post_caption.txt: platform publish text, title, description, and hashtags.
• transcript.txt: spoken in-video script generated from audio ASR.
• metadata.json: normalized platform metadata plus download and ASR status.

Output Folder Naming

Each download creates a folder with a human-readable name:
