类似切换器的UI

你可以看到 图1, the interface looks like a traditional video switcher. It has the preview window on the upper left, and the live or program window on the upper right. It also has three sources of content on the bottom. A, just below the preview and live/program windows, is for text. 低于, you see the little picture icon; this section is for still images, and you can see the three screenshots pictures here. On the bottom we have our two video sources.

Live:Air allows you to work with multiple video inputs from different sources. The video source on the left is a Canon Vixia camera attached to a Teradek VidiU Mini, a just-released miniature video encoding/streaming device. The other feed, on the left, is from an iPhone.

Click the Input button just below the live/program window and you’ll see settings for the two inputs that we have now (下面的图2).

添加更多百家乐软件

To add another input source or device, click the Add button just above the source settings dialog box, and you’ll find you have four choices, 如图所示 图3(下面). We could add another iPad, even the iPad camera from this device. We could add a movie file, or we could add our RTSP feed.

处理文本

The editor works roughly the way most editors work, right. If we wanted to add the text, we would push it into the preview window (下面的图4), and then we could either cut it or dissolve it in using the controls on the right.

If we want to get rid of the text, we click it to move it out of the preview window, and then we can just cut it out if we want. We can control the T-bar manually, if we want, or we can just use the buttons. 你可以看到 图5(下面), which shows the bottom of the transition panel on the right side of the Live:Air UI, the transition is configurable as to duration.

You also can choose different types of transitions, including the options shown in 图6(下面). You can choose a zoom dissolve, or dip to black if you’re at the end of your presentation.

图6. Options for different types of transitions.

If you want to show a picture, click the picture to put it into the preview window—just as with text-and then cross dissolve it in, or use another cut or transition of your choice. 如果你想去掉它, just click it again and hit cut, and Live:Air will return you to the camera that was there a moment ago.
