YouTube MP4 Video URL Resolver
Check YouTube watch, Shorts, and youtu.be links for MP4 options returned by the actual source response.
Supported services
How it works: paste a public YouTube URL, preview the resolver result, then choose an MP4 or remuxable video format when available.
The preview and format selector are rendered from the actual /api/resolve response for the pasted URL.
Supported URL patterns
- youtube.com/watch video URLs
- youtube.com/shorts URLs
- youtu.be short links
- m.youtube.com public video URLs
Short links
- youtu.be links are accepted when they resolve to public YouTube content.
Format availability
- MP4 appears when the source can be downloaded or remuxed as MP4.
- HD and high-quality labels appear only when YouTube exposes those formats.
- The result panel is built from the actual /api/resolve response.
Common failure reasons
- Private or deleted video
- Age, region, rights, or bot-access restriction
- No compatible MP4 video format returned
What this resolver actually returns
Formats returned by /api/resolve
| Format | Typical quality | Notes |
|---|---|---|
| MP4 (H.264 + AAC) | up to 1080p | Single-file formats are preferred so the download starts without waiting for a server-side merge |
| MP4/WebM (VP9 / AV1) | 1440p–4K when exposed | Higher resolutions are merged server-side and streamed to the browser while the file is still growing |
| M4A (AAC audio) | source bitrate | Audio-only option appears when the source exposes a separate audio format |
How the resolver handles this platform
- Long videos start streaming to your browser before the server-side download finishes, so large files do not stall waiting for response headers.
- YouTube's automated-access checks are handled server-side with retries; if YouTube still refuses, the page reports the specific reason instead of hanging.
- Shorts URLs use exactly the same resolve and download pipeline as standard watch URLs.
- Private, age-restricted, region-locked, and deleted videos fail fast with the restriction named in the result panel.
Behavior verified against the production resolver: July 2026.
