douyin-video-fetch_skill

Overview

This skill downloads Douyin (TikTok China) videos to local disk, preferring no-watermark versions when available. It outputs MP4 files named by video_id into a configurable directory and reports success or failure for each item. The tool accepts single URLs, numeric video_id, or a batch file of inputs for bulk fetching.

How this skill works

Given a Douyin URL or video_id, the skill resolves the canonical video resource and attempts to fetch an MP4 file, preferring a no-watermark stream. It supports a plain text input file with one URL or video_id per line for batch jobs and saves each file as <video_id>.mp4 under the specified output directory. The script prints per-item status and path feedback to the terminal.

When to use it

• You need original video files for analysis, editing, or model training.
• You only have a video_id and want to download the clip directly.
• You want to build a local sample library from many Douyin links.
• You plan to feed downloaded videos into downstream processing (ASR, shot detection) later.

Best practices

• Validate and normalize input links with a URL resolver before large batches.
• Respect rate limits and add delays when bulk-downloading to avoid throttling.
• Use a dedicated output directory and verify sufficient disk space beforehand.
• Run small test batches to confirm no-watermark availability and download behavior.
• Handle failures by retrying failed IDs and logging error causes for later inspection.

Example use cases

• Download a single Douyin clip by pasting its URL for offline inspection.
• Feed a list of video_ids to create a local dataset for visual analysis or model fine-tuning.
• Mirror important creator videos to a controlled archive directory for backup.
• Automate nightly pulls of new links added to an input file to maintain a fresh sample library.
