How to download private Facebook videos

Introduction

This information has been tested to piece of work at the time of publishing in Nov 2021. But Facebook'south implementation and behavior change continually, then the process may become invalid later months or years.

Did you view a video on Facebook and desire to salve it to a local file? Unfortunately, Facebook never offered a download push button for videos (dissimilar photos). You lot could try to screen-rip the video by capturing pixels, simply that destroys quality and increases file size. Ideally, you want the literal compressed video information that was delivered to your web browser for viewing, which is every bit make clean and efficient as possible, avoiding decoding and re-encoding. Sadly, y'all tin can't use the network inspector (which logs and shows all HTTP requests) to grab a single video file because the data is streamed as an unknown sequence of chunks in an unknown format.

For publicly viewable videos, just employ youtube-dl, or visit a tertiary-political party web-based downloader service where you tin paste in a Facebook URL to go a download link that is proxied through the third-party service.

For private videos (including your own uploads), the situation is catchy and the solution is not obvious. youtube-dl has command-line options to specify a username and countersign to log into Facebook. I tried this in the past and information technology sort of worked, merely not with two-factor authentication enabled (need to disable information technology temporarily), and it sometimes triggered security warnings, forcing me to modify my account password.

I found a method involving youtube-dl and browser cookies that seems to work well without triggering security problems on Facebook'southward side. Delight note that this only lets you download private videos that you are already entitled to view (due to the privacy settings of your friend'due south post); this is not a hack to download capricious individual data. Exist aware that this process is not like shooting fish in a barrel and is oriented towards those who have experience with software development tools and paradigms.

Procedure

Grooming

  1. Grab the URL of the folio containing the video that you want to download, as cleanly equally possible. If you are browsing a series of posts on the main news feed or on a person's profile/timeline, and so get a permanent link to the post that you're interested in by clicking on the timestamp text at the top of the post. Ideally, the URL should look like these examples:

    • https://www.facebook.com/jane.case.smith/posts/1234567890
    • https://www.facebook.com/jane.example.smith/videos/1234567890
    • https://www.facebook.com/0123456789/posts/1234567890/
    • https://world wide web.facebook.com/0123456789/videos/1234567890/

    The URL should not look like these (you should strip off the unnecessary parts starting from the question mark):

    • https://world wide web.facebook.com/jane.example.smith/posts/1234567890?__cft__[0]=Ywm9xVMIYfqph6vtEWxBh-fk_bUliDzhCN00uiVZXTylmYuXoPfeIZS-n15nMT4Q-rM13nSC-q4J2Wn4lmfCU-J3gi18rEu_Z_0gzfwyJnnz-gsNISO3_c0vnsZRVhPTcNaRDFt41DTE4NQdPOpM7uom&__tn__=%2CO%2CP-R
    • https://world wide web.facebook.com/0123456789/videos/1234567890/?__tn__=%2CO-R

  2. Close all Facebook tabs in your web browser. Otherwise they will continually brand requests in the background and alter your cookies.

Cookie extraction (Firefox)

I just have instructions for Mozilla Firefox right at present. While the aforementioned results tin definitely be obtained through Google Chrome, I haven't personally worked through the steps in club to document them. I have no annotate on Apple tree Safari.

  1. Notice the path of your Firefox profile binder by visiting the URL "virtually:support". Or you can manually navigate to it using a file explorer, such as "C:\Users\John Q Public\AppData\Roaming\Mozilla\Firefox\Profiles\abcd1234.default" on Windows.

  2. Ensure that you take DB browser for SQLite installed, or you are comfortable with using the sqlite3 command-line tool.

  3. From your Firefox profile folder, open the file cookies.sqlite with the tool mentioned in the previous step.

  4. Run the post-obit SQL query:

    SELECT host, 'TRUE', '/', 'TRUE', decease, name, value FROM moz_cookies WHERE host like '%.facebook.com'

  5. Select all the cells of the result table and copy the entirety as plain text. The columns should already be separated past a tab character (U+0009), which you should double-check considering it'south mandatory. Example output:

    .facebook.com	TRUE	/	TRUE	1234567890	name0	value0 .facebook.com	Truthful	/	TRUE	1618033988	name1	value1 .facebook.com	True	/	Truthful	2345678901	name2	value2

Configuring, downloading, multiplexing

  1. Create a plain text file named cookies.txt (or .tsv if you wish). Ensure that information technology uses native newlines (co-ordinate to youtube-dl'due south instructions) (LF on Unix/Linux/macOS, CR+LF on Windows). Then paste these two lines followed by a bare line:

    # Netscape HTTP Cookie File # This file is generated past youtube-dl.  Do not edit.

  2. Appending to the end of cookies.txt, paste the text obtained from the cookie extraction pace, and ensure the file ends with a native newline. The outcome should look similar:

    # Netscape HTTP Cookie File # This file is generated by youtube-dl.  Do not edit.  .facebook.com	True	/	Truthful	1234567890	name0	value0 .facebook.com	TRUE	/	TRUE	1618033988	name1	value1 .facebook.com	Truthful	/	TRUE	2345678901	name2	value2

  3. Catch the user agent string from the browser that you were using to surf Facebook. This should assistance reduce the chance of security warnings. In my instance, it is "Mozilla/5.0 (Windows NT half dozen.iii; Win64; x64; rv:94.0) Gecko/20100101 Firefox/94.0".

  4. Starting time building up the command-line string for invoking youtube-dl (don't run this yet):

    youtube-dl --cookies              CookieFile.txt              --user-agent              UserAgentString              PageUrlContainingVideo

    Example:

    youtube-dl --cookies              cookies.txt              --user-agent              "Mozilla/5.0 ... Firefox/94.0"              "https://www.facebook.com/jane.example.smith/posts/1234567890"

    The user agent value must be wrapped in quotes or escaped considering it contains spaces.

  5. Append the argument -F to our basic command line and and so execute it. This will make a asking to Facebook and return with a list of all the bachelor video and audio formats. Control-line example:

    youtube-dl --cookies cookies.txt --user-agent "Mozilla/v.0 ... Firefox/94.0" "https://world wide web.facebook.com/jane.example.smith/posts/1234567890"              -F

    Output example:

    [facebook] 1234567890: Downloading webpage [download] Downloading playlist: 1234567890 [facebook] playlist 1234567890: Collected 1 video ids (downloading 1 of them) [download] Downloading video 1 of ane [info] Bachelor formats for 9876543210: format lawmaking        extension  resolution annotation 8367172002096822a  m4a        audio only Nuance sound   65k , m4a_dash container, mp4a.40.5 (48000Hz) 4771281214258710v  mp4        256x144    DASH video   70k , mp4_dash container, avc1.4D401E, video only 957909568133806v   mp4        426x240    Nuance video  149k , mp4_dash container, avc1.4D401E, video only 339565927899773v   mp4        640x360    Nuance video  278k , mp4_dash container, avc1.4D401E, video only 2138429866841461v  mp4        852x480    Nuance video  439k , mp4_dash container, avc1.4D401F, video simply 4360441287725216v  mp4        1280x720   DASH video  862k , mp4_dash container, avc1.4D401F, video only 6595765927496358v  mp4        1920x1080  DASH video 1869k , mp4_dash container, avc1.4D4028, video only sd                 mp4        unknown hd                 mp4        unknown    (all-time) [download] Finished downloading playlist: 1234567890

    Annotation that the random numbers in the format lawmaking don't seem to mean anything. Likewise, the number subsequently "bachelor formats for" doesn't correspond with the FBID of the mail service that y'all're trying to download.

  6. Choose a video and audio format, then download information technology. Given how laborious this procedure is and how inexpensive reckoner data transfer/storage is, I strongly advise downloading the largest, highest quality formats to avoid time to come regret. Append the arguments -f format0,format1 to our bones command line and execute information technology. Case:

    youtube-dl --cookies cookies.txt --user-agent "Mozilla/five.0 ... Firefox/94.0" "https://world wide web.facebook.com/jane.example.smith/posts/1234567890"              -f              6595765927496358v,8367172002096822a

    The run of youtube-dl should produce output similar:

    [facebook] 1234567890: Downloading webpage [download] Downloading playlist: 1234567890 [facebook] playlist 1234567890: Collected ane video ids (downloading 1 of them) [download] Downloading video i of one [info] 7517720777505659: downloading video in ii formats [download] Destination: Facebook video #7517720777505659-7517720777505659.mp4 [download] 100% of vii.20MiB in 00:01 [download] Destination: Facebook video #7517720777505659-7517720777505659.m4a [download] 100% of 258.61KiB in 00:00 [ffmpeg] Correcting container in "Facebook video #7517720777505659-7517720777505659.m4a" [download] Finished downloading playlist: 1234567890

    One time over again, one of the repeated numbers on the screen ("7517720777505659" in this case) seems random and doesn't stand for with a format code or the postal service's FBID.

  7. For convenience, rename the output video file to "five.mp4" and the audio file to "a.m4a".

  8. Ensure that yous take FFmpeg installed, or take an equivalent utility that y'all're comfortable with using.

  9. Using FFmpeg, multiplex the previous video and audio files into a single audio-video output file without recompressing the data. Example command line:

    ffmpeg -i              v.mp4              -i              a.m4a              -vcodec copy -acodec copy              out.mp4

  10. You're essentially done! Pick up the output file out.mp4, then rename and shop it every bit you please.
