I made Japanese subtitle for the movie on commons.
But I encountered 2 problems.
* This namespace ignores templates. So I can't put the license template to
it. This template is not appeared on the movie.
* It ignores also line breaks of subtitle. Especially, Japanese phrases
don't have spaces for reading, so it's hard for audience to understand
Anyone has a solution to this?
So I just recently discovered that WMF is now publishing stats for media files.
So in terms of most popular videos, it seems to be mostly space and
porn. (This list is url of file minus the https://upload.wikimedia.org
part then a comma, then the number of downloads on 2015-07-25)

Anyways, thought it would be interesting to this list.
I just posted this to the Wikimania list, but wanted to let video folks
know as well:
Hi all, there are some Wikimania 2015 videos available now, guerrilla style:
As you may know, there was no central video recording of Wikimania sessions
this year. But with my own camcorder and an iPhone 5, I was able to record
26 sessions at Wikimania of varying quality. You can visit them on this
page. Any assistance to help annotate or expand on the chart is appreciated.
Also, for a glimpse of how arduous the video process can be, see:
FYI, thought folks might find this interesting -- there was a debut of a
mini-documentary at Wikimania about Tec de Monterrey using Wikipedia in the
classroom. It was very well done, and right after the talk, I helped the
filmmaker get it from his MOV format onto Wikimedia Commons thanks to the
English and Spanish subtitles are available.
There were a fair number of folks interested in video chatting at
Wikimania! A few quick updates:
* An experimental 'Schnittserver' ('Clip server') project has been in the
works for a while with some funding from ze Germans; currently sitting at
http://wikimedia.meltvideo.com/ (uses OAuth, has a temporary SSL cert, UI
is very primitive!) It is currently usable already for converting MP4 etc
source footage to WebM!
The Schnittserver can also do server-side rendering of projects using the
'melt' format such as those created with Kdenlive <https://kdenlive.org/>
and Shotcut <http://www.shotcut.org/> -- this allows uploading your
original footage (usually in some sort of MP4/H.264 flavor) and sharing the
editing project via WebM proxy clips, without generational loss on the
Once rendered, your final WebM output can be published up to Commons.
I would love to see some more support for this project, including adding a
better web front-end for managing projects/clips and even editing...
* Mozilla has an in-browser media editor thing called Popcorn.js
<http://popcornjs.org/>; they're unfortunately reducing investment in the
project, but there's some talk amon people working on it and on our end
that Wikimedia might be interested in helping adapt it to work with the
Schnittserver or some future replacement for it.
Unfortunately I missed the session with the person working on Popcorn.js,
will have to catch up later on it!
* I'm very close to what I consider a 1.0 release of ogv.js
experimentally WebM) video and audio in Safari and MS IE/Edge without
Recently fixed some major sound sync bugs on slower devices, and am

Demo of playback at https://brionv.com/misc/ogv.js/demo2/
A slightly older version of ogv.js is also running on
https://ogvjs-testing.wmflabs.org/ with integration into TimedMediaHandler;
I'll update those patches with my 1.0 release next week or so.
* Infrastructure issues:
I had a talk with Faidon about video requirements on the low-level
infrastructure layer; there are some things we need to work on before we
really push video:
- seeking/streaming a file with Range subsets causes requests to bypass the
Varnish cache layer, potentially causing huge performance problems if
there's a usage spike!
- very large files can't be sharded cleanly over multiple servers, which
makes for further performance bottlenecks on popular files again
- VERY large files (>4G or so) can't be stored at all; which is a problem
for high-quality uploads of things like long Wikimania talks!
For derivative transcodes, we can bypass some of these problems by chunking
the output into multiple files of limited length and rigging up 'gapless
playback', as can be done for HLS or MPEG-DASH-style live streaming. I'm
pretty sure I can work out how to do this in the ogv.js player (for Safari
and IE) as well as in the native <video> element playback for Chrome and
Firefox via Media Source Extensions
Assuming it works with the standard DASH profile for WebM, this is
something we can easily make work on Android as well using Google's
DASH playback will also make it easier to use adaptive source switching to
handle limited bandwidth or CPU resources.
However we still need to be able to deal with source files which may be
potentially quite large...
* List and phab projects!
As a reminder there's a wikivideo-l list:
and a Wikimedia-Video project tag in phabricator:
Folks who are interested in pushing further work on video, please feel free
to join up. There's a lot of potential awesomeness!
If you are at Wikimania, please say hello to Michael Nolan, cc'd. Mike is currently interning at Mozilla and his focus is to help "white-label" Popcorn Maker, our browser-based video editor, so others can deploy it in their web apps. He's also a big free culture and access to knowledge advocate on his campus.
Mike is attending Wikimedia to understand potential use cases and to hopefully build a prototype showing how this could work on Commons.
If this sounds interesting, would encourage you to reach out: mnolan(a)mozilla.com. Mike will be attending the hackathon and most of the video-related conference sessions. Here is the repo where he's currently working: https://github.com/nolski/popcorn-editor
Some background: Popcorn Maker is something we have been working on for a few years at Mozilla. You can try it out here: http://popcorn.webmaker.org. We will be winding down Popcorn Maker as a Mozilla service over the next few months, but naturally as an open source project we are interested in seeing whether parts of Popcorn's source code can help solve problems for others.
Believe it or not, my motivation for helping to build Popcorn Maker stemmed from the 2010 era excitement around collaborative video editing on Wikimedia projects. I think that as far as media sequencing, remix and attribution goes, Popcorn is at least 80% of the way towards awesome and should be part of experiments on Labs & conversations on how the Wikimedia project should approach collaborative media production over the next few years. I wrote more on the opportunity here:
Post-Wikimania, would love to organize a call so we can plan further with interested folks.
After meeting most of you this morning at breakfast, we have concluded
to meet for preparing our two sessions later today:
18:00 - grab dinner at the Hackathon catering (2nd floor, Don Diego 4)
and move to the 6th floor of Hilton hotel to sit outside on the garden
* Andrew Lih
* Michael Nolan
* Victor Grigas
plus anyone else who wants to present at one of the two sessions on
video content projects or video tech infrastructure and tools.
So see you later at the terrace.

are you attending this year's Wikimania and are you looking for some
interesting things to do during Wikimania Pre-Conference? Well, perhaps
this is for you: on*Thursday afternoon*, we will be hosting a workshop
for creating animated explainer videos for Wikimedia projects:
Videos have become a popular format for the dissemination of information
- especially short animated explainer videos which provide a quick
overview over complex topics. The same principle applies to Wikipedia:
videos can enrich exisiting content and provide an entertaining and
easily comprehensible access to free knowledge. Together with experts
from the simpleshow foundation Wikimedia Österreich offers workshops for
Wikimedians which are designed to learn the tricks of the trade of
screenwriting for explainer videos. In the context of this year’s
Wikimania we are happy to host such a workshop for the international
Content of the workshop
* Interested participants will learn the basic skills for creating
plots of explainer videos: how to explain complex topics in a short
and comprehensible way, how to work with cut-out animation,
storyboard conception and visualization
* The participants create and refine their scripts and storyboards
together with the simpleshow foundation after the workshop
* The realization and production of the finished storyboard will be
done by the simpleshow foundation, the result will be published
under the CC-BY-SA license on Wikimedia Commons
* The screenwriters can use the videos for Wikipedia articles and
What do you need?
* Interest in storytelling
* A topic for an explainer video
* No previous knowledge in screenwriting or video production necessary
