Paste a link to see the exact resolutions the provider reports, including 1440p and 2160p streams that arrive without audio and need a merge in your own editor.

This page is the high-definition entry point. Where the general YouTube page keeps things broad, here the focus is original quality: the 1440p and 2160p renditions the provider reports for a video, and what you need to do with them afterwards.

It accepts watch URLs, embed URLs and links to live streams. Because a live stream is still being written while you watch it, what the provider can return for one depends on its current state, and this page says so rather than pretending otherwise.

使い方

  1. ステップ 1

    Copy the video link

    Use the address bar, the embed page, or the share sheet. Watch, youtu.be and embed link shapes are all accepted here, including links to streams that are still live.

  2. ステップ 2

    Read the format list

    The provider returns the renditions it actually has. High resolutions usually appear as video-only rows with no audio; the server pairs such a row with its matching audio stream and remuxes the two into one MP4 for you.

  3. ステップ 3

    Download and merge

    Pick the video-only rendition and download it. The server fetches the matching audio stream as well and remuxes both into a single MP4, without re-encoding, so you get one file with sound instead of two that need joining.

このツールが実際に行うこと

Real quality inventory

The list is what the provider reported for that link. If no 4K rendition exists, none is shown, and no row is relabelled to look like one.

Live links handled honestly

A link to a stream that has ended may still resolve to a recorded archive, while an active one returns a partial inventory. The page reports which case you are in rather than failing silently.

Links issued on demand

Provider download addresses expire quickly, often within minutes. The download button asks for a fresh one at the moment you click, so an expired URL in the results panel is not fatal.

制限と適切な利用

  • High resolutions above 1080p are usually video-only, so you must pair them with a separate audio stream and merge the two files yourself.
  • Only download videos you own, have permission for, or that the platform permits downloading, and remember that provider links expire quickly.
  • Age-restricted, private and region-locked videos cannot be resolved without a signed-in session, and the provider reports the failure instead of working around it.

YouTube 4K & HD のよくある質問

How is this page different from the main YouTube downloader?
The other page is the general entry point. This one is built around original quality: it explains the 1440p and 2160p renditions, why those rows usually arrive silent, and what merging them back with audio involves on your own computer.
Do I need an account or software installed?
Neither. The lookup runs on the server, so your browser only needs JavaScript, and there is no account system on this site. No local tool is needed either: when picture and sound arrive separately the server remuxes them for you.
Why is my 2160p download silent?
Because the provider lists 2160p as a separate video track with no audio. Download the matching audio row at the same time and merge the two locally; this page hands you the real stream inventory rather than a file that only looks complete.
