Question how to download Facebook video in higher resolution

[jimdagys]

If you go to
facebook.com/rrlech
(any facebook account required)
and scroll down quite a bit, you will see this picture. (see attachment 1.jpg).
Then, the next post has a video and there is a comment to the video that contains a video. The video I want to download is this one. (see attachment 2.mp4). When I play this comment video in the Chrome browser, the url doesn't appear at the top of the screen, so I can't use youtube-dl. Also, chrome network developer tool doesn't seem to give me anything that will work with youtube-dl.
I used Tubedigger to download the video. However, only one resolution is available and is low (432x258). But if you play the video in full screen in Chrome browser, you can see the video has much higher resolution. My question is, how can I download the video with higher resolution?

My question is, how can I download the video with higher resolution?

By analyzing network tab, downloading the init, downloading the chunks, and finally concatenating them.

[ss]vegeta:
Thank you for your reply. I got the high resolution video from your upload and found it had no audio. So, using ffmpeg, I extracted the audio from the low resolution video from Tubedigger and, using ffmpeg, merged with your high resolution video. Perfect result.
I have some questions about how you got the video. I used Chrome network tab and found this: (See screensho). I used yt-dlp to try to download some of these entries but had no luck. Could you post exactly what you did, (also, show me what is "downloading the init").
In the below screenshot, I tried downloading with yt-dlp the whole highlighted script, and also just the part that ends in "mp4", but had no luck. I can guess that those entries (that start with numbers) are video chunks, but I was unsuccessful to download them. Also, once you downloaded all the chunks, did you use ffmpeg to combine? Also, since your video doesn't have audio, how would I get the audio if I tried to do this myself?

[[ss]vegeta]

it had no audio.

Oops, I forgot about that, sorry. Glad you worked it out though.

Could you post exactly what you did, (also, show me what is "downloading the init").

I downloaded the chunks using curl for Windows. By analyzing the video links, and their size

especially at the end "bytestart" and "byteend" I figured out these 3 are the chunks for the best resolution.
So, curl

curl "https://video.fskp4-2.fna.fbcdn.net/v/t42.27313-2/242515454_208544257885778_4146127321778027725_n.mp4?_nc_cat=101&ccb=1-5&_nc_sid=5aebc0&efg=eyJ2ZW5jb2RlX3RhZyI6ImRhc2hfZ2VuM2Jhc2ljXzVzZWNnb3BfaHEyX2ZyYWdfMl92aWRlbyJ9&_nc_ohc=V3MFd_xiVLcAX-jimWp&_nc_ht=video.fskp4-2.fna&oh=33bf2bfc816b35b4526751d0c5e95c5f&oe=6193F5FA&bytestart=1065&byteend=2355510" -o 1.mp4

curl "https://video.fskp4-2.fna.fbcdn.net/v/t42.27313-2/242515454_208544257885778_4146127321778027725_n.mp4?_nc_cat=101&ccb=1-5&_nc_sid=5aebc0&efg=eyJ2ZW5jb2RlX3RhZyI6ImRhc2hfZ2VuM2Jhc2ljXzVzZWNnb3BfaHEyX2ZyYWdfMl92aWRlbyJ9&_nc_ohc=V3MFd_xiVLcAX-jimWp&_nc_ht=video.fskp4-2.fna&oh=33bf2bfc816b35b4526751d0c5e95c5f&oe=6193F5FA&bytestart=2355511&byteend=5361813" -o 2.mp4

curl "https://video.fskp4-2.fna.fbcdn.net/v/t42.27313-2/242515454_208544257885778_4146127321778027725_n.mp4?_nc_cat=101&ccb=1-5&_nc_sid=5aebc0&efg=eyJ2ZW5jb2RlX3RhZyI6ImRhc2hfZ2VuM2Jhc2ljXzVzZWNnb3BfaHEyX2ZyYWdfMl92aWRlbyJ9&_nc_ohc=V3MFd_xiVLcAX-jimWp&_nc_ht=video.fskp4-2.fna&oh=33bf2bfc816b35b4526751d0c5e95c5f&oe=6193F5FA&bytestart=5361814&byteend=7548488" -o 3.mp4

Now, the first part at the end says

bytestart=1065

so we realize we are missing the init file, 0 to something. If we change the resoltion of the video, we see some parts loading up.
The init file is usually small, around 1 kb. So this is it

curl "https://video.fskp4-2.fna.fbcdn.net/v/t42.27313-2/242515454_208544257885778_4146127321778027725_n.mp4?_nc_cat=101&ccb=1-5&_nc_sid=5aebc0&efg=eyJ2ZW5jb2RlX3RhZyI6ImRhc2hfZ2VuM2Jhc2ljXzVzZWNnb3BfaHEyX2ZyYWdfMl92aWRlbyJ9&_nc_ohc=V3MFd_xiVLcAX-jimWp&_nc_ht=video.fskp4-2.fna&oh=33bf2bfc816b35b4526751d0c5e95c5f&oe=6193F5FA&bytestart=0&byteend=960" -o init.mp4

Also, once you downloaded all the chunks, did you use ffmpeg to combine?

No, I used type command in Windows.

type init.mp4 1.mp4 2.mp4 3.mp4 > video.mp4

This is a lot of manual work, prolly can be done in a really easier way, maybe IDM as someone mentioned (I never got used to that program) but it's fun for me.

Also, since your video doesn't have audio, how would I get the audio if I tried to do this myself?

Probably in a similar way. I would guess these are the links for the audio

[lomero]

yes maybe from network tab is the best way to download.
anyway why complicate your life when IDM rip streaming in one shot audio+video at best resolution? (720p)

No need to merge ,You can simply remove the range

&bytestart=0&byteend=960

Nice, thanks.

[lomero]

or better, if you don't have IDM, we have a lot of online site that allow this.
simply search "download video facebook"
try this link: https://www.fdown.net/
put video link and download it

put video link and download it

That was the problem with this video, there wasn't a simple "video link" because it was in a comment.

[TubeDigger]

I used Tubedigger to download the video. However, only one resolution is available and is low (432x258). But if you play the video in full screen in Chrome browser, you can see the video has much higher resolution. My question is, how can I download the video with higher resolution?

Select highest resolution in Facebook player settings. Start to download all detected files. After some time put mouse over downloading filenames to see media information in tooltip and therefore check which file is video and which file is audio. Download these two files and rest files remove from downloading. Later join together these two downloaded audio and video files using option 'Join' in TubeDigger's converting dialog.

this is direct link:

[jimdagys]

Ok, I was able to get the 720p with audio following Mr Tubedigger's directions. Key point is to select highest resolution from gear icon in facebook video when playing the video in Tubedigger browser. Make sure the audio is sounding when playing the video in Tubedigger browser. Video and audio download separately and then easily combined with Tubedigger convert>join tool.

[jimdagys]

[ss]vegeta,
I already got the high resolution download with Tubedigger, but I'm trying to "back engineer" what you did.
For example you posted this (which seems to be the last chunk):

https://video.fskp4-2.fna.fbcdn.net/v/t42.27313-2/242515454_208544257885778_4146127321778027725_n.mp4?_nc_cat=101&ccb=1-5&_nc_sid=5aebc0&efg=eyJ2ZW5jb2RlX3RhZyI6ImRhc2hfZ2VuM2Jhc2ljXzVzZWNnb3BfaHEyX2ZyYWdfMl92aWRlbyJ9&_nc_ohc=V3MFd_xiVLcAX-jimWp&_nc_ht=video.fskp4-2.fna&oh=33bf2bfc816b35b4526751d0c5e95c5f&oe=6193F5FA&bytestart=5361814&byteend=7548488" -o 3.mp4

I used Chrome network developer tools and played the high resolution facebook video and among lots of urls, got this (which looks similar to what you got):

https://video-ort2-1.xx.fbcdn.net/v/t42.27313-2/242515454_208544257885778_4146127321778027725_n.mp4?_nc_cat=101&cb=3b11de2f-6a33e524&ccb=1-5&_nc_sid=5aebc0&efg=eyJ2ZW5jb2RlX3RhZyI6ImRhc2hfZ2VuM2Jhc2ljXzVzZWNnb3BfaHEyX2ZyYWdfMl92aWRlbyJ9&_nc_ohc=NAeV9JomYg0AX-LhrOM&_nc_ht=video-ort2-1.xx&oh=f743a8eaac4c4e24c9eefbb1a5bd6446&oe=619660BA&bytestart=6715599&byteend=7548488

I put this in yt-dlp and got an error message. But I notice the beginning of my code (https://video-ort2-1.xx.fbcdn.net/) is different than your code (https://video.fskp4-2.fna.fbcdn.net/).
Can you explain why mine is different than yours? What method did you use to get your code?
Also, you said you used curl to download. Why did you use curl? Would your code work with yt-dlp? (I'm used to using yt-dlp.)

Why are you still complicating stuff when notaghost told you an easier method, without chunks?
You also made it work with Tubedigger.

I guess ytdlp can't handle chunks like that, ytdlp is for other stuff.
Why is the beginning of my URL different than yours, you'll have to ask Facebook. But it doesn't matter. I get the full video from YOUR link also, the way notaghost descirbed.
I didn't use any method to get my code, just network tab in developer tools.
I used curl because chunks like that can't be downloaded directly in the browser (or it's a browser problem, I don't know) and curl is like the tool with best reputation for data transfers.
The code will not work with ytdlp.

[jimdagys]

Ok, I was able to download the high resolution video with audio.
I downloaded curl 32 bit for my computer.
(https://curl.se/windows/)
and placed the unzipped folder directly on the C drive.
I had to cut off the range at the end of the urls for both video and audio (as shown by Notaghost above post #7).

curl "https://video-atl3-2.xx.fbcdn.net/v/t42.27313-2/242515454_208544257885778_4146127321778027725_n.mp4?_nc_cat=101&cb=3b11de2f-6a33e524&ccb=1-5&_nc_sid=5aebc0&efg=eyJ2ZW5jb2RlX3RhZyI6ImRhc2hfZ2VuM2Jhc2ljXzVzZWNnb3BfaHEyX2ZyYWdfMl92aWRlbyJ9&_nc_ohc=NAeV9JomYg0AX_FDMah&_nc_ht=video-atl3-2.xx&oh=7102921d28b2d59282205e6369ab5dca&oe=6197178A" -o video.mp4

I used ffmpeg to combine video/audio.
ffmpeg -i video.mp4 -i audio.mp4 -c copy output.mp4
To make it easier so I didn't have to sort through a lot of urls from facebook on the chrome network developer tool, I first scrolled down on the facebook page to just before the video that I wanted, and then started the network tool.
