Download a YouTube video as MP4, up to 2160p

Because 360p is all that video offers. The list is generated from what the source returns, and some uploads were published with a single low rung. If the same link shows more resolutions in another browser, the difference is the exit IP the parse ran on, not the page.

No. 2160p appears only when YouTube still exposes a 2160p stream and the current server IP is allowed to see it. Older uploads, some music videos and region-limited items top out lower, so read the ladder as a measurement of this request rather than a promise.

Google sometimes answers the server IP with a bot check instead of a format list. When that happens the parse fails rather than inventing entries. A cookie from a signed-in browser session is the documented workaround, and retrying later from a different exit IP often clears it too.

No. Both run on our side. yt-dlp resolves the link and ffmpeg performs the merge for anything above 1080p, and you only ever receive a finished MP4 through an ordinary browser download. There is no extension, no desktop app and no command line involved.

Nothing is overlaid. The MP4 you get is the stream YouTube served, merged if the rung required it, with no ClipVault marks and no intro card. The only processing applied is the joining of picture and sound, and no re-encode happens below 1080p.

Yes, provided it is a normal YouTube video behind the link. Shorts parse through the same path, arrive vertical, and use the same six-rung ladder. The two-hour cap is generous for a Short, and small vertical files usually need no merge because one stream already carries both tracks.

The request is rejected with a clear error before any download begins, because the cap is two hours per video. Long DJ sets, restreamed events and audiobook uploads typically exceed it. The page has no way to split a URL into parts, so a shorter source is the only route.

Two jobs are processed at a time across the service, one per IP. A third request is answered with a busy error instead of queueing silently. There is no daily quota and no account, so you can start another pair the moment the first two have finished.
