People have watched video with automatic captions more than 23 million times, and have automatically translated captions more than 7.6 million times.

The number of manually-created caption tracks has more than tripled thanks largely to automatic caption timing technology.

Just recently, we’ve reduced the error rate in our speech recognition algorithms by 20%

Art Imitates Life: Re-enacting Prop 8 Trial on YouTube

16 Haziran 2010 Çarşamba

YouTube channelWhat is the inspiration behind MarriageTrial on YouTube?We realized on January 13, when the U.S. Supreme Court blocked the broadcast of California’s Proposition 8 trial, that this was really significant. When the American public was actively prevented from accessing these public proceedings on YouTube — precisely because it is so accessible — well, that’s a flat-out dare. We had to fill the void. We both believe that citizens should have access to the judicial process that will likely determine the future of marriage equality for our entire country.

First video in the series:

How has YouTube helped meet the goals of your project?
There is really no better venue for 60+ hours of film. Many blogs and news media websites have embedded our videos. Because of this, our coverage has become an integral part of the media’s reporting on the trial. Ultimately, this serves our primary goal, which is to bring transparency to the court process.

We have followed behind the scenes of the trial, as well. When the Defendant-Intervenors filed Motions to Strike testimony, we were able to “red-line” the proposed strikes, guiding people to the excerpts the motion sought to exclude from the official record. In fact, our re-enactment will remain accessible, regardless of what may be redacted from the official transcript. That is an extraordinary victory for transparency in our judicial process.

YouTube’s “time seek” functionality allows us to link evidence that is introduced in the trial. Most of our viewers are active consumers of the information, many of them reading along with the transcripts and searching for further references to each witness’s testimony. Yet many others just run the videos in the background. One of our subscribers, who cranks up her speakers and cleans the house, told us she considers our channel better than the books on tape.

Has the amount of attention been a surprise?
We were astonished at the press coverage we received, from local and national media. The international press, too, took a great interest in our project. The fact that they could access our video on YouTube made it very easy to cover and most TV and radio outlets broadcast clips directly from our YouTube channel. In a way, our YouTube Channel served as an Electronic Press Kit (EPK), which saved us quite a bit of time and marketing money.

We were featured in the New York Times, then on Bill Moyers Journal on PBS. Other national and international coverage followed. These reports commented on the way we were getting this video out to the masses…that our effort signifies a new type of “citizen journalism,” not only accessible to the world, but faster and cheaper to produce than traditional forms of media broadcast.

Describe the use of captions in your videos.
A few hours after we uploaded our first chapters, automatic captions miraculously appeared! We then formatted the official court transcripts and used YouTube’s auto-alignment tool to produce accurate captions. Our actors followed the transcripts word-for-word and the captions make it clear what a great job they did. It was so easy to provide captions, which, traditionally, can be very expensive (often prohibitively) for filmmakers. The new Interactive Transcript feature is a great way for users quickly jump to specific parts of the video directly from the transcript.

Comprehension and retention of the concepts introduced by witnesses, for example, get a major boost when viewers can read along, without having to pull up the PDF transcript. And of course, the trial re-enactment is immediately available to people with hearing loss, as well as people whose native languages are not English. The auto-translate function makes these captions available in so many languages. We could never have even approached this level of accessibility as independent filmmakers.

If the ruling goes into appeals, will you continue with the re-enactments?
Yes. We plan to follow Perry v. Schwarzenegger to the U.S. Supreme Court. According to most experts, this court’s ruling will be appealed to the U.S. Ninth Circuit, regardless of whether it repeals or confirms California’s Proposition 8. From there, it will inevitably be appealed to the highest court. We expect the first appeal within six months or so, then for it to go to Washington, D.C. by next fall. We are already planning for those re-enactments. It’s a bit early to cast the Supreme Court justices just yet, but we know that is in our future.

Bottom line, this case as a landmark in America’s civil rights history. We are proud to have created this permanent record as a resource for generations to come. Its ultimate impact is tied to YouTube as an integral part in our country’s political and cultural tapestry.

The Future Will Be Captioned: Improving Accessibility on YouTube

4 Mart 2010 Perşembe

recent studiescaption featureauto-captioning

While we plan to broaden the feature to include more languages in the months to come, currently, auto-captioning is only for videos where English is spoken.

Just like any speech recognition application, auto-captions require a clearly spoken audio track. Videos with background noise or a muffled voice can't be auto-captioned. President Obama's speech on the recent Chilean Earthquake is a good example of the kind of audio that works for auto-captions.

Auto-captions aren't perfect and just like any other transcription, the owner of the video needs to check to make sure they're accurate. In other cases, the audio file may not be good enough to generate auto-captions. But please be patient -- our speech recognition technology gets better every day.

Auto-captions should be available to everyone who's interested in using them. We're also working to provide auto-captions for all past user uploads that fit the above mentioned requirements. If you're having trouble enabling them for your video, please visit our Help Center: this article is for uploaders and this article is for viewers.

YouTube's Top 10 Launches of 2009

31 Aralık 2009 Perşembe

Did you know that we released more features in 2009 than in 2007 and 2008 combined? This made it the busiest year on record for the YouTube product and engineering teams. Some of these launches, like support for 1080p, made sizable splashes, while others, like "trending topics" appearing at the bottom of the browse page, went out with less fanfare. With so much going on, we wanted to pause before the new year begins to review the things that hopefully made the biggest impact on your overall YouTube experience:

Auto-Share - As part of our wider effort to integrate YouTube into the social and communication platforms you use every day, AutoShare automatically syndicates your YouTube activity to Facebook, Twitter and Google Reader.

1080p - In November, we unveiled support for videos in 1080p (aka "full HD"). Want to test it out? Check out this video.

Auto-Speech Recognition - Google's automatic speech recognition (ASR) technology, coupled with YouTube's captioning system, makes videos more accessible to the deaf and hearing impaired. This same speech recognition technology can create machine-generated captions, which can then be translated into 51 languages.

Mobile Website for Smartphones - Watching videos on -- and uploading videos from -- cell phones is more popular than ever. To meet this demand, we launched a new mobile website designed to make using YouTube on smartphones like the iPhone, G1 and Palm Pre a lot easier.

YouTube XL - YouTube XL optimizes YouTube for large screens. In addition to offering larger text and simplified navigation, XL has a continuous play feature, allowing you to search for a topic, hit "play" and then kick back for an uninterrupted viewing experience.

VEVO - VEVO.com is a partnership that blends Google and YouTube's technology with music videos from a broad catalog of artists from Universal Music Group, Sony Music and EMI. The site hopes to redefine the way people watch and engage with music online, as well as change the way the digital and music industries do business with each other.

Feather - Feather is a stripped-down version of the page on which any video plays. Without all but the basic features, the page loads more quickly and videos play back faster. Give it a whirl in TestTube or click here.

3D - In July, one of our engineers used his free time to implement easier viewing options for 3D videos on YouTube. Here's a brief overview video.

Real-Time Comment Search - In October, we released the ability to search YouTube comments in real-time. The comment appears on a continuously updated results page, and "trending topics" indicates the hottest topics of conversation on YouTube at that particular moment.

Shows & Movies - In April, we rolled out a destination sporting hundreds of movies and thousands of full-length TV episodes. Offerings have included film classics like Taxi Driver, Ghostbusters and the Spaghetti Western Trilogy, as well as current TV shows from broadcasters like C4 and Channel 5 in the UK.

Which of these features is your favorite? Please use the poll in the top right corner of this blog to let us know what you've found to be most useful in '09, or leave a comment below if there's another feature that had an important impact on your YouTube life.
