Facebook Share Links (share/r, share/v, share/p): Which Ones Transcribe
Copy link in the Facebook app gives you facebook.com/share/r/, /share/v/ or /share/p/. What each one points at, how often each transcribed across 1,931 share links, and why the failures fail.
Short answer
A Facebook share link — facebook.com/share/r/ for a Reel, /share/v/ for a video, /share/p/ for a post — is a short code that Facebook expands into the real page. Reel and video share links transcribe when the video is public: over 90 days, 94% of Reel links and 88% of video links pasted into SubGrab did. Most failures were videos Facebook shows only to logged-in viewers.
Tap Share, then Copy link, in the Facebook app and you no longer get the video's address. You get a short code under facebook.com/share/. That is now how most Facebook videos reach us: of 2,689 Facebook transcriptions in the 90 days to 9 October 2026, 1,931 started from a share link.
They work well, with one exception and one recurring cause of failure. Here is what each kind is and how often each transcribed, counted per transcription rather than per attempt.
What r, v and p Mean
| Link | Points at | Transcribed, 11 Jul – 9 Oct 2026 |
|---|---|---|
| facebook.com/share/r/… | A Reel | 1,034 of 1,099 (94.1%) |
| facebook.com/share/v/… | A video | 721 of 824 (87.5%) |
| facebook.com/share/p/… | A whole post | 0 of 6 |
| facebook.com/reel/… | A Reel's own address, for comparison | 601 of 630 (95.4%) |
The code after the letter is not the video's number. It is a key that only Facebook can expand: open the link and Facebook redirects you to the real page. A transcription tool has to follow that redirect too. SubGrab accepts all three kinds and follows them.
Reel share links transcribe almost exactly as well as a Reel's own address. Video share links fail more often, and mostly for a reason that has nothing to do with the link.
Why a Share Link Fails: the Login Wall
SubGrab began naming Facebook's login wall separately from other errors on 2 September. Since 3 September, 135 share links have failed, and 111 of them were the login wall: the video was limited in some way — typically to friends, to a group's members, or to logged-in viewers.
It plays for you because you are logged in. A transcription service is not, and Facebook answers it with a login page instead of the video. Retrying cannot change that, and neither can a different link to the same video. What works:
- A public copy of the video — the same clip posted to a public page, or anywhere else public
- The file itself — if you have it, upload it directly; uploads run to about 50 minutes per file
Why some Facebook videos never transcribe goes through the login wall in detail, including how to check a video before you spend a credit on it.
Post Links (/share/p/)
A post link points at the whole post, which may hold a video, a set of photos or only text. None of the 6 post links pasted into SubGrab in 90 days produced a transcript. That is too small a sample to call a rule, so treat it as a warning: if the post contains a video, open the video on its own and copy the link from there. You will get a /share/v/ or /share/r/ link, or the video's own address.
Extra Text, Doubled Links and Other Copy Accidents
The code is everything Facebook needs, so anything after it in the address is noise. Links reach us with a sentence typed after them, a second copy of the link glued to the end, the tail of a markdown link, or an invisible formatting character picked up from a chat app.
SubGrab now cuts a share link back to its code before fetching it. Until this October it did not: 7 of the 8 links that arrived like that failed and were reported as deleted, though every one of them pointed at a video that existed. When we re-ran the cut-down links, 6 of the 8 reached their video directly, and the other 2 met a login wall.
The ?mibextid= Tail
Links copied from the app often end in ?mibextid= followed by a short code. It does not change which video the link opens. Share links carrying it transcribed 193 times out of 226 in the same 90 days, in line with share links in general. Leave it on or delete it.
Quick Checklist
- A Reel or a public video: paste the share link as it is — it works the same as the video's own address
- It fails with a login message: the video is not public; only a public copy or the file will work
- A /share/p/ post link: open the video in the post and copy that link instead
- A live broadcast: see Facebook Live transcripts — a stream that is still live has no recording to transcribe yet

Frequently asked
What do the r, v and p mean in a Facebook share link?
They say what the link points at: r is a Reel, v is a video, and p is a whole post. The code after the letter is not the video's number but a key that Facebook expands into the real address when the link is opened. Reel and video links transcribe like the video's own address; post links often do not lead straight to a video.
Why does my Facebook share link fail when the video plays for me?
Almost always because you are logged in and the transcription service is not. Since 3 September, 111 of the 135 Facebook share links that failed in SubGrab hit Facebook's login wall: the video was limited, typically to friends, a group, or logged-in viewers. Nothing about the link is wrong, and retrying does not help. Only public videos can be transcribed from a link.
Do I need to remove ?mibextid= from a Facebook link?
No. The Facebook app adds it to links it copies, and it does not change which video the link opens. Share links carrying it transcribed 193 times out of 226 in our last 90 days, in line with share links in general. Leave it on or delete it, whichever is easier.
