イントロダクション

Wirecastでダイナミックなウェブキャストを簡単に作成できます。複数のウェブカム、イメージ、タイトルやムービーを使って細部にこだわったマルチメディア放送が可能です。

Wirecast
はシーンのユニークな概念を導入しています。選択したカメラ、グラフィックのオーバーレイ、ムービーやタイトルを一つのシーンにまとめます。シーンリストを一度作成すると、ブロードキャスト間をクリック一つで切り替えられます。

リアルタイムでブロードキャストをコントロールするのは簡単です。視聴者に見せたいカメラを切り替えている間、Wirecastの複数のレイヤーサポートでウェブキャストにBGMを簡単に挿入できます。

Wirecast
QuickTime Streamingアーキテクチャで放送します。インターネットやLAN上に「単一放送」できます。ウェブキャストを拡大したい場合は、ブロードキャストをQuickTime Streamingサーバに転送するだけです。視聴者はQuickTime Playerや直接ウェブページに入っているものを通してウェブキャストを見ることができます。

機能ハイライト




          バージョン 3.0の新機能

          一番重要と思われる機能:

          hdviconHDV camera Support. A first for a live solution, Wirecast 3 adds native support for the latest HDV cameras and decks. Connect your camera via FireWire and Wirecast will automatically recognize and configure it. Supporting both 1080i (with deinterlacing) and 720p in 16:9 aspect ratios, Wirecast's support for HDV cameras brings affordable High Definition quality to everyone. As you'd expect, Wirecast continues its support for multiple simultaneous cameras, enabling live HDV switching on a personal computer for the first time.

          Desktop Presenter. A common workflow is the webcasting of presentations and lectures, which until now, had involved using extra hardware to bring the output of another machine into Wirecast. To solve this problem, Wirecast 3 introduces the Desktop Presenter. The Desktop Presenter is a small application, running on either Mac or Windows, that transmits the screen of the computer, over the local network, to Wirecast in real time. The data sent from the Desktop Presenter is automatically compressed, so you can continue to use images, animations and video on your machine. Presenter discovery is handled automatically by Bonjour networking, making configuration easy. The Desktop Presenter allows you to select a particular monitor or region of the screen, and can even focus on an individual window.
          qticonBuilt-in Streaming Server. Setting up a Streaming Server for small webcasts has always been a chore, so Wirecast 3 now builds the industry standard Darwin Streaming Server directly in. There are now no system services to install, no XML configuration files to maintain and no hassles; just a couple of clicks and your webcast is live. When it comes time to scale your webcasts up, the same powerful broadcasting controls are still available.

          Chroma Key enhancements. Wirecast 3 improves upon the great real time performance and quality of the original Chroma Key. The algorithm has been upgraded to include a proprietary dynamic spill suppression algorithm that automatically delivers significantly higher fidelity. The end product being better results with higher performance.
