# TikTok Scraping with yt-dlp

yt-dlp is a CLI for downloading video/audio from TikTok and [many other sites](https://github.com/yt-dlp/yt-dlp/blob/master/supportedsites.md).

## Setup

```bash
# macOS
brew install yt-dlp ffmpeg

# pip (any platform)
pip install yt-dlp
# Also install ffmpeg separately for merging/post-processing
```

---

## Download Patterns

### Single Video

```bash
yt-dlp "https://www.tiktok.com/@handle/video/1234567890"
```

### Entire Profile

```bash
yt-dlp "https://www.tiktok.com/@handle" \
  -P "./tiktok/data" \
  -o "%(uploader)s/%(upload_date)s-%(id)s/video.%(ext)s" \
  --write-info-json
```

Creates:

```
tiktok/data/
  handle/
    20260220-7331234567890/
      video.mp4
      video.info.json
```

### Multiple Profiles

```bash
for handle in handle1 handle2 handle3; do
  yt-dlp "https://www.tiktok.com/@$handle" \
    -P "./tiktok/data" \
    -o "%(uploader)s/%(upload_date)s-%(id)s/video.%(ext)s" \
    --write-info-json \
    --download-archive "./tiktok/downloaded.txt"
done
```

### Search, Hashtags & Sounds

```bash
# Search by keyword
yt-dlp "tiktoksearch:cooking recipes" --playlist-end 20

# Hashtag page
yt-dlp "https://www.tiktok.com/tag/booktok" --playlist-end 50

# Videos using a specific sound
yt-dlp "https://www.tiktok.com/music/original-sound-1234567890" --playlist-end 30
```

### Format Selection

```bash
# List available formats
yt-dlp -F "https://www.tiktok.com/@handle/video/1234567890"

# Download specific format (e.g., best video without watermark if available)
yt-dlp -f "best" "https://www.tiktok.com/@handle/video/1234567890"
```

## Filtering

### By Date

```bash
# On or after a date
--dateafter 20260215

# Before a date
--datebefore 20260220

# Exact date
--date 20260215

# Date range
--dateafter 20260210 --datebefore 20260220

# Relative dates (macOS / Linux)
--dateafter "$(date -u -v-7d +%Y%m%d)"           # macOS: last 7 days
--dateafter "$(date -u -d '7 days ago' +%Y%m%d)" # Linux: last 7 days
```

### By Metrics & Content

```bash
# 100k+ views
--match-filters "view_count >= 100000"

# Duration between 30-60 seconds
--match-filters "duration >= 30 & duration <= 60"

# Title contains "recipe" (case-insensitive)
--match-filters "title ~= (?i)recipe"

# Combine: 50k+ views from Feb 2026
yt-dlp "https://www.tiktok.com/@handle" \
  --match-filters "view_count >= 50000" \
  --dateafter 20260201
```

---

## Metadata Only (No Download)

### Preview What Would Download

```bash
yt-dlp "https://www.tiktok.com/@handle" \
  --simulate \
  --print "%(upload_date)s | %(view_count)s views | %(title)s"
```

### Export to JSON

```bash
# Single JSON array
yt-dlp "https://www.tiktok.com/@handle" --simulate --dump-json > handle_videos.json

# JSONL (one object per line, better for large datasets)
yt-dlp "https://www.tiktok.com/@handle" --simulate -j > handle_videos.jsonl
```

### Export to CSV

```bash
yt-dlp "https://www.tiktok.com/@handle" \
  --simulate \
  --print-to-file "%(uploader)s,%(id)s,%(upload_date)s,%(view_count)s,%(like_count)s,%(webpage_url)s" \
  "./tiktok/analysis/metadata.csv"
```

### Analyze with jq

```bash
# Top 10 videos by views from downloaded .info.json files
jq -s 'sort_by(.view_count) | reverse | .[:10] | .[] | {title, view_count, url: .webpage_url}' \
  tiktok/data/*/*.info.json

# Total views across all videos
jq -s 'map(.view_count) | add' tiktok/data/*/*.info.json

# Videos grouped by upload date
jq -s 'group_by(.upload_date) | map({date: .[0].upload_date, count: length})' \
  tiktok/data/*/*.info.json
```

> **Tip:** For deeper AI-powered analysis of scraped content (summarization, sentiment analysis, trend detection), use SkillBoss API Hub via `POST https://api.skillbossai.com/v1/pilot` with `type: "chat"`. Load JSONL/CSV exports into Python with `pandas` for engagement scatter plots, posting frequency charts, or comparing metrics across creators.

## Ongoing Scraping

### Archive (Skip Already Downloaded)

The `--download-archive` flag tracks downloaded videos, enabling incremental updates:

```bash
yt-dlp "https://www.tiktok.com/@handle" \
  -P "./tiktok/data" \
  -o "%(uploader)s/%(upload_date)s-%(id)s/video.%(ext)s" \
  --write-info-json \
  --download-archive "./tiktok/downloaded.txt"
```

Run the same command later—it skips videos already in `downloaded.txt`.

### Authentication (Private/Restricted Content)

```bash
# Use cookies from browser (recommended)
yt-dlp --cookies-from-browser chrome "https://www.tiktok.com/@handle"

# Or export cookies to a file first
yt-dlp --cookies tiktok_cookies.txt "https://www.tiktok.com/@handle"
```

### Scheduled Scraping (Cron)

```bash
# crontab -e
# Run daily at 2 AM, log output
0 2 * * * cd /path/to/project && ./scripts/scrape-tiktok.sh >> ./tiktok/logs/cron.log 2>&1
```

Example `scripts/scrape-tiktok.sh`:

```bash
#!/bin/bash
set -e

HANDLES="handle1 handle2 handle3"
DATA_DIR="./tiktok/data"
ARCHIVE="./tiktok/downloaded.txt"

for handle in $HANDLES; do
  echo "[$(date)] Scraping @$handle"
  yt-dlp "https://www.tiktok.com/@$handle" \
    -P "$DATA_DIR" \
    -o "%(uploader)s/%(upload_date)s-%(id)s/video.%(ext)s" \
    --write-info-json \
    --download-archive "$ARCHIVE" \
    --cookies-from-browser chrome \
    --dateafter "$(date -u -v-7d +%Y%m%d)" \
    --sleep-interval 2 \
    --max-sleep-interval 5
done
echo "[$(date)] Done"
```

## Troubleshooting

| Problem                                  | Solution                                                                    |
| ---------------------------------------- | --------------------------------------------------------------------------- |
| Empty results / no videos found          | Add `--cookies-from-browser chrome` — TikTok rate-limits anonymous requests |
| 403 Forbidden errors                     | Rate limited. Wait 10-15 min, or use cookies/different IP                   |
| "Video unavailable"                      | Region-locked. Try `--geo-bypass` or a VPN                                  |
| Watermarked videos                       | Check `-F` for alternative formats; some may lack watermark                 |
| Slow downloads                           | Add `--concurrent-fragments 4` for faster downloads                         |
| Profile shows fewer videos than expected | TikTok API limits. Use `--playlist-end N` explicitly, try with cookies      |

### Debug Mode

```bash
# Verbose output to diagnose issues
yt-dlp -v "https://www.tiktok.com/@handle" 2>&1 | tee debug.log
```
