Dear Deryck,

Thanks for your great job!

For the closing ceremony, do you think you can recover from Livestream?

Best regards,

Hello Wikimaniacs again!

We've uploaded and released all the available Wikimania 2013 videos onto WMHK's YouTube channel: http://www.youtube.com/user/wikimediahk

The submission pages now have links to the videos on YouTube. The videos can also be searched on YouTube by name of lead author or title of presentation; some titles have been modified to fit the title length limit.

A few sessions' footage (including the closing ceremony, unfortunately) are corrupt and couldn't be recovered. In a few other sessions, somebody accidentally turned off or forgot to turn on the camera, so only part of the session was recorded; these incomplete videos were uploaded anyway.

Next step:

We have two 2TB HDDs, each containing a complete copy of the footage (one of them also has the corrupted footage fragments). We are happy to mail them to someone at WMF or a European / North American chapter so they can process the footage, re-render it (and improve the audio quality!), and upload them to Commons.

Deryck

PS. Thanks Enoch Tam and Walter Wan who contributed to the uploading work!

Thanks for the extensive explanation, and as someone who's helped with Wikimania video in the past, I absolutely feel your pain and commend you for doing what you have so far.

Downloading from YouTube violates their TOS, though you'll notice people do it all the time.

No. We figured that uploading to YouTube is the only way we can get all the videos out before Wikimania 2014.

(Longer, more technical answer follows)
We performed a series of pilot tests in December and early January and found two main technical problems with uploading the videos from Hong Kong to Commons.

The first one is bandwidth. We have about 1TB of video footage. Because Hong Kong is on the opposite side of the planet from the WMF datacenters, we can only eke out an average speed of 50kB/s even on a "fast" connection in Hong Kong. At that rate it'll take 250 computer-days (plus extra time cost due to errors etc) of non-stop uploading to get it done. We don't have that many dedicated volunteers who are willing to donate that much machine time. In contrast, we can get an average speed of 500kB/s uploading to YouTube because they have a local node in Hong Kong. Enoch Tam (aka. "ET", many of you will remember him for all the errands he ran at Wikimania) and myself are donating all our machine idle time to the task, so we're confident it'll be done in less than a month.

The second challenge is rendering. YouTube isn't just a video CDN; it is a combined rendering and distribution service. The footage we got from SocRec is in unedited 2-4GB chunks of M2T and MTS files, which Commons cannot handle. Uploading to Commons would require the use of rendering software (and a lot of computing) to convert and edit them to OGV. This requires a further amount of volunteer dedication, video-editing software, and computing power which we don't have. The strategy at the moment is that we upload the raw footage to YouTube, then edit them into sessions using YouTube's browser video editor.

To see the details and progress of what we're doing, see https://wikimania2013.wikimedia.org/wiki/Video_upload .

We did contemplate, at one point about two weeks ago, that we shouldn't even attempt to upload the videos from Hong Kong, and just mail the 2TB external HDD with the raw footage to WMF or WMUK. Now that Andrew pointed out that downloading and keeping a copy of YouTube videos violates their TOS regardless of licence, I guess we could've just given up back then. I guess the best course of action now is that we continue uploading and editing the videos on YouTube. If someone at WMF or WMUK is willing to render and edit the videos again from scratch, we'll send them the HDD after we're done here.

Any plans to upload them to Commons or Internet Archive, or is this something we can get volunteers to help with?

The only reason is that in general, downloading and keeping videos from YouTube violates their terms of service. Even if they are CC licensed.

Thanks.

Good evening Wikimaniacs!

We now have a distributed effort by multiple volunteers in Hong Kong to upload all the video footage from Wikimania 2013 onto YouTube. If you gave a presentation or workshop at Wikimania (and haven't requested that we don't video you), keep an eye on WMHK's YouTube channel:
http://www.youtube.com/user/WikimediaHK

The plan is that all videos will be available by the end of February.

We'd be grateful if you can watch your video and see if there are any defects, because we can't watch every second of the uploaded videos to check them!
