720p WebM[edit]
(copied from User_talk:Tbayer_(WMF)#YouTube_webm:)
I noticed File:WMF Monthly Metrics Meeting November 7, 2013.ogv in ogv and I see:
$ youtube-dl -F https://www.youtube.com/watch?v=YgXT3aA5CyE [youtube] Setting language [youtube] YgXT3aA5CyE: Downloading video webpage [youtube] YgXT3aA5CyE: Downloading video info webpage [youtube] YgXT3aA5CyE: Extracting video information Available formats: 22 : mp4 [720x1280] 43 : webm [360x640] 18 : mp4 [360x640] 5 : flv [240x400] 36 : 3gp [240x320] 17 : 3gp [144x176] 136 : mp4 [720p] (DASH Video) 135 : mp4 [480p] (DASH Video) 134 : mp4 [360p] (DASH Video) 133 : mp4 [240p] (DASH Video) 160 : mp4 [192p] (DASH Video) 141 : m4a [256k] (DASH Audio) 140 : m4a [128k] (DASH Audio) 139 : m4a [48k] (DASH Audio)
Too bad; does YouTube ever create webm derivatives at full resolution too? Do you know why they don't use their own preferred format webm for the videos they create themselves? --Nemo 11:43, 16 November 2013 (UTC)

- Yes, all the WebM files in Category:Video recordings from the WMF Metrics and Activities Meetings came directly from YouTube without conversion, and the August to October videos were all available in 720p when I transferred them. It looks like these 720p WebMs have been removed retroactively from YouTube, leaving only the MP4 version of the highest resolution. (However, per [1][2] it seems also possible that the 720p WebMs are still there, but are not detected - I checked with JDownloader 2 beta, youtube-dl and the bookmarklet.)

- (YouTube not accepting VP9-codec as upload option to their own servers and also not offering VP8 HD transcodes is some weird kind of irony, indeed....)
- I guess there is nothing we can do except to hope that google publishes the WebM HD transcodes again. My (optimistic) guess would be that they are trying to convert all of their videos to VP9. However, I have stopped my activity to import CC-videos from youtube and created Category:Videos with missing WebM HD transcode on youtube in the meanwhile. --McZusatz (talk) 10:33, 17 November 2013 (UTC)
- Seems like we get them back as 4K-VP9: http://news.cnet.com/8301-1023_3-57616481-93/youtube-2014-is-the-year-of-the-high-def-stream/ --McZusatz (talk) 22:54, 2 January 2014 (UTC)
bookmarklet[edit]
I tried the github b.let. Dl options appeared, got a name from the clipboard, but what happened after I o keyed? No indication if its slowly being uploaded to commons, or tried and failed to dl locally? Danny lost (talk) 23:31, 22 March 2014 (UTC)
- It is only to download a video. (Use right click to download). --McZusatz (talk) 22:24, 23 March 2014 (UTC)
WebM transcoding[edit]
Now YouTube don't offer anymore good WebM versions, we must proceed differently. We have to download audio and mp4 video tracks separately, then start encoding in WebM:
format code extension resolution note 140 m4a audio only DASH audio , audio@128k (worst) 160 mp4 144p DASH video , video only 133 mp4 240p DASH video , video only 134 mp4 360p DASH video , video only 135 mp4 480p DASH video , video only 136 mp4 720p DASH video , video only 137 mp4 1080p DASH video , video only 17 3gp 176x144 36 3gp 320x240 5 flv 400x240 43 webm 640x360 18 mp4 640x360 22 mp4 1280x720 (best)
We want tracks 140 (audio) and 137 (MP4 at 1080p)
$ youtube-dl -f 140 -o input.m4a https://www.youtube.com/... $ youtube-dl -f 137 -o input.mp4 https://www.youtube.com/...
Then we run a two-pass encoding. For owners of an old CPU, we can replace the -deadline best option by -deadline good. According to the documentation, the quality is almost the same. Also consider replacing -threads 8 option by the number of cores available on your processor.
$ ffmpeg -i input.mp4 -i input.m4a -codec:v libvpx -deadline best -cpu-used 0 -qmin 10 -qmax 42 -maxrate 500k -bufsize 1000k -threads 8 -an -pass 1 -f webm -y /dev/null $ ffmpeg -i input.mp4 -i input.m4a -codec:v libvpx -deadline best -cpu-used 0 -qmin 10 -qmax 42 -maxrate 500k -bufsize 1000k -threads 8 -codec:a libvorbis -b:a 128k -pass 2 -f webm output.webm
We now have a quality video in WebM format (ok, it will always be worse than the MP4 original version, but it's free :)

- Thanks for this interesting information! If one chooses to upload as OGV instead of WebM, it's still possible to convert the full MP4 video (including audio) in one step using ffmpeg2theora. Regards, Tbayer (WMF) (talk) 18:39, 24 April 2014 (UTC)
I just took the opportunity of a presentation here in Google SF office to ask the technical lead for engineering practices, youtube whether we'll be able to download 1080p webm videos any time soon. He said that downloading is usually nefarious so there is no real work being done on it; but that for things like downloading your own video or livestream "it's just not done yet". Not happening any time soon I guess. :( --Nemo 18:52, 10 June 2015 (UTC)
Hi Nemo, sounds like bad news. For reference:

Is there a WebM version?[edit]
I figured, since most readers don't have their computer set up to view Wikimedia videos, the caption of each video ought to include a link to a Youtube version which all home computers, smartphones or whatever, can see even if the owner doesn't know what a "file format" is. Which means, to convert the format, I ought to upload to Youtube first in whatever format my camera made, then download the WebM version which Wikimedia thinks is the best one, thus killing two birds with one stone. So, I signed on with my old Google account, and now my little video is [ here] oh, I'm not allowed to link to it. Always people smarter than me are finding ways to make things more difficult. Anyway, this being my first Youtube upload, I have no idea how to make it send me a WebM version. I'm beginning to suspect this path is leading into a dead end or at least a thicket, and figuring out how to convert the file on my own old Windows machine will be easier, but am I missing something fairly obvious that ought to be mentioned on this page?

Template:YouTube CC-BY[edit]
YT videos using CC-BY-4.0 (not 3.0) exist, maybe {{YouTube CC-BY}} cited as {{YouTube}} on the project page, and the project page itself, need an update. I can't tell if they switched generally from 3.0 to 4.0 or offer a choice, my only example is File:All Writs Act.ogv. –Be..anyone (talk) 07:45, 6 December 2014 (UTC)

Could a bot confirm CC license status?[edit]
There are currently over 8,500 files needing human review in Category:License review needed (video), and most of them are probably from YouTube. There are probably untold other videos and screen captures that have not had any review. Could a bot me made to check and confirm YouTube files automatically upon upload, similar to {{Flickrreview}}? Maybe {{YouTubeReview}}? --Animalparty (talk) 03:12, 22 January 2019 (UTC)
Can’t find license info?[edit]
I’m having trouble getting the license info for File:Lu Xiaojun training.jpg. I can usually click on “show more” to see if the license is CC-BY or All Rights Reserved, but when I go to the YouTube source, I don’t see anything there. Is there another way to verify the license? Ytoyoda (talk) 12:25, 22 May 2019 (UTC)
- Looks like it had no license, and has now been deleted. - Jmabel ! talk 03:40, 4 June 2020 (UTC)
Thumbnail of video, uploaded from Youtube[edit]
Is is possible to add a custom thumbnail on the video uploaded to commons? --Gpkp (talk) 12:45, 3 June 2020 (UTC)
- Isn't that something you have to do in the video file? - Jmabel ! talk 03:42, 4 June 2020 (UTC)
- @Jmabel: ; Seems possible via any software or scripts. What I do like to know is, Youtube has an option to upload custom thumbnail on the videos uploaded in it. Anything similar in here? I used a video converter, whose output-videos I uploaded to commons and a random video-frame is auto-selected as a thumbnail. --Gpkp (talk) 11:28, 4 June 2020 (UTC)
Downloading[edit]
I've split the "downloading" and "WebM" sections to a separate page; they are very technical, and off-putting for lay users. Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 11:59, 3 November 2020 (UTC)
Missing license?[edit]
I can't find where CC videos are anymore. It looks like YouTube took the license out of the video's description. Clicking "Show more" does nothing. I can still sort by CC files but they're not labeled as such when I click on them. Kingofthedead (talk) 00:42, 7 December 2020 (UTC)
Youtube Filter also includes "Creative Commons"[edit]
The YouTube search filter has an option for "Creative Commons." I didn't see it on the project page and was wondering if it was worth mentioning. Magiciandude (talk) 16:43, 10 December 2020 (UTC)
Government videos for mass upload[edit]
The Welsh Government have changed their licences on all their 1,400+ videos on YouTube to a OGL and a CC-BY. I've started converting a handful into WebM HD format and uploaded them by hand, and I'm now looking for a mass converter-uploader tool. Commons:video2commons doesn't work on my two machines (tried over a 3 months period), and the coder doesn't seem to be interested in a dialog on the Talk page. Any ideas, please? Llywelyn2000 (talk) 12:15, 12 January 2021 (UTC)
- Similar predicament. There's a lot of Californian and Floridian videos on YouTube as well and they're all public domain. – Illegitimate Barrister (talk • contribs), 18:44, 18 May 2023 (UTC)
Which CC licence uses Youtube?[edit]
Hi there! anyone knows which CC licence is used on youtube? I can't find any details anywhere. Is it considered a simple CC BY ? So anything with "Creative Commons Attribution license (reuse allowed)" is useable on Commons (if the original image is really CC of course)? Triton (talk) 00:07, 11 June 2021 (UTC)
