Default video download codec for yt-dlp was downloading videos in webm format that was super small in size but when I wanted to play those in my Plex Media server, it was converting those for my Samsung TV. the default command simply downloads it into current folder which I didn’t like. Also I wanted subtitles which the default command doesn’t do. So the problem was three fold; find the correct codec, download subtitles and create organised folder structure. After few testing, I found these yt-dlp commands for subtitles, selecting codec, creating organised folder structures that worked quite well for me. Also default subtitle was VTT format and I prefer SRT format, so I kind of decided to add that into the command to convert that as well. In summary, this detailed guide covers essential commands for downloading videos with proper codec selection, subtitle integration, and automated folder organisation ideal for Plex media servers using yt-dlp.

Understanding yt-dlp Command Structure

Before diving into specific yt-dlp commands, understanding the basic command structure helps you customise downloads effectively:

yt-dlp [OPTIONS] URL

Options control everything from video quality to subtitle languages and output locations. Let’s explore the most useful commands for organised media management.

Essential yt-dlp Commands for Basic Downloads

Default Command

yt-dlp URL

Download Best Quality Video

yt-dlp -f "bestvideo+bestaudio" URL

This downloads the highest quality video and audio streams available, merging them into a single file.

Download Best Quality with Codec Preference

yt-dlp -S "codec:h265" -f "bestvideo*+bestaudio/best" URL

Prioritises H.265 (HEVC) codec for better compression whilst maintaining quality—perfect for reducing storage requirements.

List Available Formats

yt-dlp -F URL

Displays all available video and audio formats with their IDs, resolutions, and codecs before downloading. So you might select e.g. MKV instead.

yt-dlp Commands with H.265 Codec Selection

I prefer H.265 codec. H.265 codec provides approximately 50% better compression than H.264 whilst maintaining video quality, making it ideal for large media libraries and Plex servers. If you have a different opinion, leave a comment and I will test that.

Download with H.265 Preference

yt-dlp -S "codec:h265" -f "bestvideo*+bestaudio/best" URL

This command prioritises H.265 encoded videos but falls back to the best available format if H.265 isn’t available.

Force Specific Resolution with H.265

yt-dlp -S "res:1080,codec:h265" -f "bestvideo[height<=1080]+bestaudio/best" URL

Limits download to 1080p maximum with H.265 codec preference, perfect for balancing quality and file size.

Download 4K with H.265

yt-dlp -S "res:2160,codec:h265" -f "bestvideo[height<=2160]+bestaudio/best" URL

Downloads 4K content when available, prioritising H.265 encoding for manageable file sizes.

Subtitle Download Commands

Subtitles enhance accessibility and are essential for foreign language content. These commands for subtitles download handle various subtitle scenarios.

Download English Subtitles

yt-dlp --write-subs --sub-langs "en" URL

Downloads English subtitles as a separate file alongside the video.

Download Multiple Subtitle Languages

yt-dlp --write-subs --sub-langs "en,es,fr,de" URL

Downloads subtitles in English, Spanish, French, and German, creating separate files for each language.

Convert Subtitles to SRT Format

yt-dlp --write-subs --sub-langs "en" --convert-subs srt URL

Downloads subtitles and converts them to SRT format, offering the widest compatibility with media players and Plex.

Download Auto-Generated Subtitles

yt-dlp --write-auto-subs --sub-langs "en" --convert-subs srt URL

Downloads YouTube’s automatically generated subtitles when manual subtitles aren’t available.

Embed Subtitles in Video File

yt-dlp --embed-subs --sub-langs "en" URL

Embeds subtitles directly into the video file (works with MKV and MP4 containers).

Download All Available Subtitles

yt-dlp --write-subs --sub-langs "all" --convert-subs srt URL

Downloads subtitles in every available language, useful for international content collections.

Organised Folder Structure Commands

Proper organisation is crucial for maintaining large media libraries, especially when integrating with Plex. These yt-dlp commands creates nicely organised folder hierarchies.

Basic Organisation by Channel and Video

yt-dlp -o "%(uploader)s/%(title)s/%(title)s.%(ext)s" URL

Creates structure:

Channel Name/
└── Video Title/
    └── Video Title.mp4

Complete Plex-Ready Download Command

yt-dlp -S "codec:h265" -f "bestvideo*+bestaudio/best" --write-subs --sub-langs "en" -o "%(uploader)s/%(title)s/%(title)s.%(ext)s" URL

yt-dlp -S "codec:h265" -f "bestvideo*+bestaudio/best" --write-subs --sub-langs "en" --convert-subs srt -o "%(uploader)s/%(title)s/%(title)s.%(ext)s" URL

This command:

• Prioritises H.265 codec
• Downloads best quality
• Includes English VTT (default) or convted SRT subtitles
• Organises by channel and video name

The best command to download YouTube videos with correct codec, subtitles and a very organised folder structure

yt-dlp -S "codec:h265" -f "bestvideo*+bestaudio/best" --write-subs --sub-langs "en" --convert-subs srt -o "%(uploader)s/%(title)s/%(title)s.%(ext)s" URL

Result:

Tech Channel/
└── Amazing Tutorial/
    ├── Amazing Tutorial.mp4
    └── Amazing Tutorial.en.srt/vtt

Playlist Organisation

yt-dlp -S "codec:h265" -f "bestvideo*+bestaudio/best" --write-subs --sub-langs "en" -o "%(playlist_uploader)s/%(playlist)s/%(title)s.%(ext)s" PLAYLIST_URL

yt-dlp -S "codec:h265" -f "bestvideo*+bestaudio/best" --write-subs --sub-langs "en" --convert-subs srt -o "%(playlist_uploader)s/%(playlist)s/%(title)s.%(ext)s" PLAYLIST_URL

Creates playlist-based structure:

Channel Name/
└── Playlist Name/
    ├── Video 1.mp4
    ├── Video 1.en.srt/vtt
    ├── Video 2.mp4
    └── Video 2.en.srt/vtt

Batch Download Commands

Download multiple videos efficiently whilst maintaining organisation.

Download Entire Channel

yt-dlp -S "codec:h265" -f "bestvideo*+bestaudio/best" --write-subs --sub-langs "en" --convert-subs srt -o "%(uploader)s/%(title)s/%(title)s.%(ext)s" CHANNEL_URL

Download Specific Playlist Items

yt-dlp --playlist-items 1,5,7-10 -o "%(uploader)s/%(playlist)s/%(title)s.%(ext)s" PLAYLIST_URL

Downloads videos 1, 5, 7, 8, 9, and 10 from the playlist.

Download Latest 5 Videos from Channel

yt-dlp --playlist-end 5 -o "%(uploader)s/%(title)s/%(title)s.%(ext)s" CHANNEL_URL

Reverse Playlist Order

yt-dlp --playlist-reverse -o "%(uploader)s/%(playlist)s/%(title)s.%(ext)s" PLAYLIST_URL

Configuration File Approach

Create a persistent configuration file for default settings.

Linux/macOS: ~/.config/yt-dlp/config

Windows: %APPDATA%\yt-dlp\config.txt

Example configuration:

# Video quality and codec
-S codec:h265
-f bestvideo*+bestaudio/best

# Subtitles
--write-subs
--sub-langs en
--convert-subs srt

# Organisation
-o %(uploader)s/%(title)s/%(title)s.%(ext)s

# Metadata
--embed-metadata
--embed-thumbnail

# Download archive
--download-archive ~/.yt-dlp-archive.txt

With this configuration, simply run:

yt-dlp URL

All settings apply automatically.

Next Steps

Now that you’ve pretty much covered yt-dlp commands for subtitles, codec  selection and creating folder structures:

1. Install yt-dlp on your system if you haven’t already
2. Set up YTPTube web GUI for easier management (coming soon)
3. Explore Docker-based media automation

For home server setups, check out our Unraid NAS installation guide covering complete media server infrastructure.

Conclusion

The above yt-dlp commands for subtitles, codecs and creating organised folder strcutures provides good control over your video library management. From codec selection to subtitle handling and folder organisation, these commands create professional-grade media collections compatible with Plex and other media servers. For me, the key to successfully playing videos without buffering was using quality control (H.265 codec), accessibility (subtitles), and organisation (structured folders).

That’s it, Enjoy!
