yt-dlp
yt-dlp is a command-line media downloader and metadata tool for supported sources. This page covers format selection, output templates, subtitles, post-processing and keeping source access within permitted use.
What yt-dlp provides
yt-dlp retrieves media and metadata from supported sources through a command-line workflow. Format availability, authentication, rate limits and source terms can change; a successful command does not establish permission to copy or redistribute the result.
Make output reproducible
Choose a format deliberately, keep a predictable output template and separate temporary fragments from finished files. Subtitles, thumbnails, metadata and post-processing can create extra outputs, so inspect the directory after each small test instead of assuming one input creates one file.

yt-dlp format and output guide
Use a permitted short media item as a test, inspect available formats, download one selected output with a clear template and verify the resulting file before scaling up.
Before you start
- Confirm the source, account access and permission to save the selected media.
- Prepare a dedicated output directory with enough space for media and temporary files.
- Decide whether subtitles, thumbnails, metadata or post-processing are required.
Installation steps
- 01
Verify the command and working directory
Install yt-dlp for the platform, run its version and help output and confirm that the command resolves to the intended binary before processing any URL.
- 02
Inspect formats first
Use the metadata inspection mode on a permitted short item, compare video, audio, subtitle and container options and choose a format that the target player can open.
- 03
Download one controlled output
Apply a stable output template, write to the dedicated directory and keep temporary fragments separate so the resulting filename and extension can be reviewed.
Quick start
- 01
Save subtitles and metadata deliberately
Request only the subtitle languages and metadata fields needed for the task, then check that sidecar files do not reveal private account or path information.
- 02
Verify post-processing
Inspect the final container, audio and video streams, duration and subtitle encoding; compare a checksum or media probe result when the file is being archived.
- 03
Keep retries bounded
Use conservative rate and retry settings, stop when authentication or access rules change and avoid turning a transient error into an uncontrolled batch.
Usage tips
- Treat cookies, session files and account credentials as sensitive; keep them out of shell history and shared logs.
- A format listing can change over time, so record the selected format and resulting container with the archive.
- Keep source, temporary fragments and final outputs in separate paths with a cleanup rule.
Troubleshooting and uninstall
Why is the selected format unavailable?
Reinspect the source, account state and current format list, then choose a compatible video and audio combination rather than copying a stale format identifier.
Why is the final file missing audio or subtitles?
Check the selected streams, merge or post-processing support, subtitle language and final container, then repeat with a short permitted sample.
- Preserve useful output recordsKeep the command version, format choice and output verification notes needed to reproduce or audit the permitted archive.
- Remove the tool and credentialsUninstall yt-dlp through the platform, remove unused cookies or session files and clear temporary fragments only after confirming final outputs.
Frequently asked questions
Does yt-dlp grant permission to save online media?
No. The user must review the source terms, account rights and applicable permission before retrieving, storing or sharing media.
Why can a command succeed but produce an unusable file?
The selected streams, container, codec, post-processing tools or subtitle encoding may not match the target player. Inspect the final file rather than relying on exit status alone.
Should cookies be included in a shared command?
Treat cookies and session data as credentials. Keep them outside shared scripts and logs, and remove them when the task is complete.
Does the download require an extraction code?
The Quark entry does not require one; the four-character code for the Baidu entry is shown beside its download entry.
