Download Facebook Videos in HD — Public, Page, and Reel

VidMost logs into Facebook through its built-in browser to capture the authenticated HD source for VOD, Reels, and Watch content. For Live, VidMost can detect the playable stream once Facebook publishes a replay or VOD.

Why Facebook videos are hard to download

The platform-specific obstacles a downloader has to handle.

HD source is only exposed to authenticated sessions

Facebook's player serves an SD variant to unauthenticated requests and only exposes the HD source URL after the session is logged in. Anonymous scrapers consistently get SD only.

Most content is behind a login wall

Public-page videos can be viewed without an account, but group videos, friends-only posts, and Watch series typically require sign-in. The video URL is meaningless without the right session cookies.

Multiple URL formats for the same video

Facebook video URLs come in many shapes — facebook.com/watch/?v={id}, facebook.com/{user}/videos/{id}, fb.watch/{short}, m.facebook.com/{...}. Downloaders that pattern-match on one URL shape break on the others.

Live broadcasts use a different pipeline than VOD

While a Facebook Live is in progress, video flows as a DASH manifest in real time. After the broadcast ends, Facebook publishes a VOD over the next minutes-to-hours. The same fb.watch URL can return different stream types depending on when you hit it.

How VidMost detects the video

VidMost's smart sniffer ships with a Facebook adapter that intercepts the source URL from video.fbcdn.net (and related Facebook CDN hosts) when the player loads in the built-in browser. Every detected variant is listed in the right sidebar, with a recommended (best-match) HD source highlighted. The browser signs into Facebook first so the player exposes the HD source URL; SD-only fallbacks happen when the HD source has not been requested by the player yet.

URL pattern / signal Format Note
video.fbcdn.net/v/.../video.mp4?...&_nc_cat=... MP4 Direct HD source for feed video and Reels — exposed only after the player loads with a valid session.
video.fbcdn.net/.../manifest.mpd DASH Used for Facebook Live; capture depends on the stream format available in the browser session.

Supported formats

Container Codec Resolution Notes
MP4 H.264 + AAC up to 1080p HD Feed video and Watch series. Source resolution caps depend on uploader and upload date.
MP4 H.264 + AAC 720p / 1080p vertical (typically 1080×1920) Reels — captured the same way as feed video.
MP4 (Live replay / VOD) H.264 + AAC varies If Facebook publishes a replay or VOD after a Live broadcast ends, it can be downloaded the same way as feed video.

Bulk download from Facebook

Paste a Reels feed, a creator's Reels or videos tab, a Watch topic, or a creator watch page, and VidMost queues every video item it finds on the entry page.

Reels feed facebook.com/reel/

Public Reels feed.

Creator Reels tab facebook.com/{slug}/reels

Every Reel posted by the creator. The profile.php?id={id}&sk=reels variant is also supported for profiles without a vanity slug.

Watch topic facebook.com/watch/topic/{id}/

Topic aggregation page.

Creator videos hub facebook.com/{slug}/videos

Every video posted by the creator. profile.php?id={id}&sk=videos also supported.

Watch (creator center) facebook.com/watch/{username}/

Creator's Watch center page.

Common failure causes

Cause

Video downloads in SD only — HD source URL not captured

Fix

The HD URL is only exposed after the player fully loads HD. Refresh the page inside VidMost's browser, wait for the player to switch to HD, then re-queue. The HD source will then be visible to the sniffer.

Cause

Private group video — not a member

Fix

You must be an approved member of the group. Sign in through VidMost's browser with the account that has group access; if the video plays for you in the browser, the sniffer will capture it.

Cause

Geo-restricted content

Fix

Some Watch series and rights-restricted videos are blocked outside specific regions. A VPN to a permitted region applies before launching VidMost; the browser will then load the video as if you were local.

Cause

Facebook Live just ended — VOD not yet processed

Fix

After a Live ends, Facebook takes minutes-to-hours to publish the replay. Wait until the fb.watch URL plays as a normal VOD, then retry.

Compliance & responsible use

Facebook's Terms of Service do not permit downloading other users' content without their consent. VidMost is intended for your own posts, content from pages or groups where you have explicit permission to save material, or videos licensed for reuse. Do not download from private groups you were not invited to, and do not redistribute downloaded Facebook content without the original poster's permission.

The hardest part of downloading from Facebook is not the technical interception — it is getting Facebook to serve the HD source URL in the first place. Facebook deliberately exposes only an SD variant to unauthenticated or freshly-loaded sessions, and only attaches the HD source URL after the player has loaded HD in an authenticated browser. Tools that scrape the page once and look for a .mp4 link will consistently come away with SD, even on videos that clearly play in HD on facebook.com. The HD URL exists, but it is only visible after a specific sequence of player events.

VidMost’s approach is to let the built-in browser engine drive that sequence while a Facebook adapter in the smart sniffer catches the result. The browser signs in, loads the page, plays the video for long enough that the HD variant gets requested, and the adapter intercepts video.fbcdn.net for the HD source URL — every detected variant is listed in the right sidebar with the recommended HD source highlighted. From the user’s perspective it is just a paste-and-download. This is also what makes VidMost work for Reels (same CDN, same exposure pattern, just vertical) and Watch series (same CDN, sometimes with additional region checks). For Facebook Live, the adapter detects the playable stream once Facebook publishes a replay or VOD; live capture during the broadcast itself depends on the stream format available in the browser session. If the adapter ever lags a platform change, kernel record mode is the universal fallback — a floating toolbar appears over the playing video and records while it plays.

Frequently asked questions

Why does my Facebook video download in SD instead of HD?
Facebook only exposes the HD source URL after the player has loaded HD in the browser. Refresh the page inside VidMost's built-in browser, wait for the player to upgrade to HD, then re-queue the download — the HD source will be captured.
Can I download videos from a private Facebook group?
Only if you are an approved member of that group. Sign in through VidMost's built-in browser with the account that has access; if the video plays for you in the browser, the sniffer can capture it.
Does VidMost work for Facebook Live?
If Facebook publishes a replay or VOD after the broadcast ends, VidMost can detect the playable stream the same way it handles other Facebook video. Live capture during the broadcast itself depends on the stream format available in the browser session.
Can I download Reels with VidMost?
Yes. Reels use the same fbcdn.net source pipeline as feed video, just at vertical resolution. Paste the Reel URL the same way you would a regular video.
Can I bulk-download a creator's videos or Reels?
Yes. Paste the creator's videos hub (facebook.com/{slug}/videos) or Reels tab (facebook.com/{slug}/reels) and VidMost queues every video item on the page. Watch topic pages (/watch/topic/{id}/) and creator watch centers (/watch/{username}/) are also supported entry pages.
