from datetime import datetime
# Configuration
DOWNLOAD_FOLDER = "YouTube_Series_" + datetime.now().strftime("%Y%m%d")
Path(DOWNLOAD_FOLDER).mkdir(exist_ok=True)
# Premium download settings
ydl_opts = {
    # Video selection (prioritize 1080p AV1/VP9 codecs)
    'format': '(bestvideo[vcodec^=av01][height<=1080]/bestvideo[vcodec^=vp9][height<=1080]/bestvideo[height<=1080])+bestaudio',
# Output configuration
    'outtmpl': f'{DOWNLOAD_FOLDER}/%(series)s - S%(season_number)sE%(episode_number)s - %(title)s.%(ext)s',

Key Features & Benefits

1. Intelligent Quality Selection

• Resolution Priority: 1080p → 720p → 480p fallback
• Modern Codecs: Prefers AV1/VP9 over H.264 for better compression
• Audio Quality: Selects highest available bitrate (often 256kbps+)

2. Professional File Organization

├── English_Series - S01E01 - Introduction.mkv
├── English_Series - S01E01 - Introduction.jpg
├── English_Series - S01E01 - Introduction.en.vtt
└── English_Series - S01E01 - Introduction.info.json

3. Comprehensive Metadata

• Subtitles (automatic + manual)
• Thumbnails
• YouTube metadata (views, description, etc.)
• Episode numbering (when available)

Implementation Guide

1. Prerequisites

# Install requirements
pip install yt-dlp
brew install ffmpeg  # macOS
choco install ffmpeg # Windows
sudo apt install ffmpeg # Linux

2. Running the Downloader

def download_series(urls):
    with yt_dlp.YoutubeDL(ydl_opts) as ydl:
        for url in urls:
            try:
                print(f"\n📥 Downloading: {url}")
                ydl.download([url])
                print("✅ Download completed successfully")
            except Exception as e:
                print(f"❌ Failed to download {url}: {str(e)}")
# Load URLs from CSV
with open('series_urls.csv') as f:
    reader = csv.reader(f)
    urls = [row[0] for row in reader]
download_series(urls)

Advanced Customizations

1. For 4K HDR Content

'format': '(bestvideo[vcodec^=av01][height<=2160][fps>30]/bestvideo[vcodec^=vp9.2][height<=2160]/bestvideo[height<=2160])+bestaudio',
'postprocessors': [{
    'key': 'FFmpegVideoConvertor',
    'preferedformat': 'mkv',
    'preferedcodec': 'hevc',  # H.265 for 4K
}]

2. For Podcasts/Audio Focused

'format': 'bestaudio/best',
'extractaudio': True,
'audioformat': 'opus',  # Better than mp3
'audioquality': '0',    # Maximum quality
'postprocessors': [{
    'key': 'FFmpegExtractAudio',
    'preferredcodec': 'opus',
}]

Ethical & Legal Considerations

1. Fair Use Compliance

• Only download content you have rights to
• Follow YouTube’s Terms of Service

2. Responsible Downloading

'ratelimit': 5000000, # 5MB/s limit 'sleep_interval': 2, # Seconds between downloads

3. Storage Recommendations

• 1080p videos: ~150MB per 10 minutes
• 4K videos: ~1GB per 10 minutes

Troubleshooting

IssueSolutionCodec errorsAdd '--recode-video mkv'

Slow speedsUse 'external_downloader': 'aria2c'

Geo-blockedAdd 'geo_bypass': True

Age-restrictedInclude 'age_limit': 0

Conclusion

This professional-grade solution offers:

• 🏆 Maximum quality preservation
• 🗂️ Perfect organization for series
