Streaming Salsa: Producing the 2012 World Latin Dance Finals Webcast

的 第三届世界拉丁舞杯总决赛 drew more than 600 competitors from more than 40 countries, all hoping to be chosen champions of Latin dancing. 决赛于12月13日至15日举行, 2012 at the Miami Airport Convention Center (MACC)—the dancers performed energetic, expressive Latin dances before a packed auditorium.

With global interest in this colorful, electrifying 和 passionate competition, 艾伯特·托雷斯制作公司活动组织者问道 Mobeon to produce a live, multicamera webcast of the finals for the third straight year. 每年, Mobeon—a live broadcast production company 和 new media consultancy in Santa Monica, 加州.-派了一个摄制组去反贪会, 安装几个高清摄像机, 和 produced all aspects of the high-quality annual webcast, 哪个是标准清晰度的.

Mobeon首席执行官马克·阿拉马斯决定使用 Telestream的Wirecast Pro live streaming production software for the 2012 世界拉丁舞杯 Finals as they had done the previous year. 2011年的决赛, when the Mobeon crew brought two Sony HD camera signals into Wirecast via FireWire ports on an Apple MacBook Pro, they were extremely pleased with the quality of the webcast 和 the positive viewer response.

流媒体+ ISO记录

2012年世界拉丁舞杯决赛, Alamares说, "I wanted to raise the production bar even higher. 除了从两个高清摄像头变成三个高清摄像头, I also wanted to ISO record each camera's HD signal while switching between them for the live program stream, 哪个是标准定义的."

ISO recording would allow Albert Torres—a world-renowned Latin music 和 dance promoter—to repurpose the raw 1080p HD footage into a documentary, 其他视频项目.

While searching online for an advanced solution that could meet his production requirements including ISO record, 阿拉马雷斯于2012年11月被发现 news of a joint, integrated solution from Telestream和matrix. It enabled multi-camera recording by pairing Telestream Wirecast live streaming production software for Windows with the Matrox VS4 四通道视频采集卡.

安装VS4卡时, companion plug-in software called Matrox ISO Record automatically installs within Wirecast. After the software is configured for ISO record, the video signals from each of up to four cameras are captured onto a hard drive at that native video quality level.

CDN-friendly

Wirecast lets operators switch between these camera inputs, 视频剪辑, 添加图片, 标题, 和转换, 和 even chromakey video against a greenscreen for virtual sets, 在一系列广泛的生产特征中.

While Mobeon 和 艾伯特·托雷斯制作公司 used Ustream, Wirecast users can also stream live via YouTube 和 Justin.tv as well as content delivery 网works (CDNs) like Akamai 和 聚光灯下. Mobeon obtained a hard-wired Inter网 connection from the MACC 和 the adjacent DoubleTree Hilton hotel that delivered between 1 和 1.5 Mbps.

Mobeon was able to put together a complete multicamera streaming system including Wirecast Pro with the Matrox VS4 card for under $4,000. Users can install the card (in a PCI-express slot inside the computer) along with the Matrox drivers 和 Wirecast Pro software. Wirecast users can enlist the help of manufacturer-certified systems builders to install 和 configure their systems for them for an additional cost. Once this setup is done, users need only to plug in their cameras 和 start streaming.

"This price-point is a real game changer," says Alamares. "It puts the ability to stream very high-quality, HD multicamera shows within reach of many who previously couldn't afford to do it. This price advantage helped us deliver the uncompromised production quality the 世界拉丁舞杯 Finals dem和ed while staying within a very tight production budget."
