Youtube: 80% daily videos available in WebM?

[yishan]

In one presentation last year,
http://www.streamingmedia.com/conferences/west2010/presentations/SMWest-2010-WebM.pdf,
it was said "YouTube HTML5 beta (80% daily videos available in WebM)".

However, when looking YouTube, many videos are still not having WebM
choice (I do see WebM ones, but rare, at least not 80% of all Youtube
videos).

Does somebody illustrate the meaning of "80%"?

[Mike Melanson]

When you see stats like that, the fine print tends to read "80% of the
videos that people actually *care* about." So, 80% of the most commonly
viewed videos. The long tail of video has not necessarily been
transcoded yet.

Thank for the response.
After some trial I found clips with viewer count larger than 500,000
will have webm format in high probability.
I originally thought webm will apply to all NEW videos to fasten the
deployment, if removing H.264 is the goal...

At first they only did the ones available in HD. Maybe they don't
encode the low resolution ones yet.

I don't think removing H.264 will be possible for many years to come.

I confirm that a lot of new videos don't have webm version... which i
don't understand ?

Did you take into account that at the moment videos with ads are
always shown in the Flash player?

Correct - as of today webm encoding at youtube is still selectively enabled for videos provided to us at HD resolution or already in the WebM format.

We are continually re-evaluating this selectivity and if you want to help get rid of it, the best thing to do is to make the vp8 encoder faster. There's been a lot of good work in this direction over the past few months, and it's all in the public libvpx git repository...

until the <ads> tag support has been added? :)

[antistress]

Yes, i'm aware of that. However a lot of recent SD videos without ads
nor annotations are not available in WebM.
Therefore if only a few of new videos are available in WebM, the gap
will keep on growing. We're not even talking of reducing the gap :-/
