回顾:电视直播6

Telestream Wirecast is a premier live production software program that we’ve reviewed many times, and watched its evolution closely over the last several years. 在版本5中, Telestream简化了界面, 操作更直观, 并增加了x264输出, 提高生产质量. 在版本6中, Telestream has converted the program to 64-bit operation, 哪些应该提高性能和稳定性. Telestream还增加了几个关键功能, 包括播放列表, 社交媒体支持, iOS设备输入, 即时回放.

像以前的版本一样, Wirecast 6有两个版本, Wirecast Studio ($495 retail) and Wirecast Pro ($995 retail), 并不是所有的新功能都包含在两个版本中. As I discuss the program’s new capabilities in this review, I’ll indicate which features are available only in the Pro version. Note that Telestream is offering special upgrade pricing, so it will cost only $149 to upgrade from Wirecast Studio 5 to Wirecast Studio 6, 从Wirecast 5 Pro到Wirecast 6 Pro售价295美元.

查看以前的评审(Wirecast 1.0;  Wirecast 5)和教程(Wirecast 5)，以获得程序操作的概述. In this review, I’ll describe how the new features work and how they might fit into your productions. 让我们从播放列表开始.

播放列表

播放列表 are groups of content that you can queue and play back at any point in a Wirecast production. They’re great for creating sequences for beginning and ending your productions, 还有在幕间休息的时候, 集, 半, 或局. 因此，它们几乎适用于任何生产. 在Wirecast, a Playlist can contain pre-recorded VOD files or live cameras, so you could use a playlist to cycle through various cameras in your production, 或者在视频点播内容中穿插直播材料.

You can create a playlist using the New Document function in the four-up display in the timeline, or by dragging and dropping one piece of content over another. One of the nicest additions to the Wirecast interface is a trimming function in the Preview window which you can use to cut the heads and tails from your VOD clips. If you want to trim your VOD content for playback in the playlist, it’s easiest if you trim before dragging the clip into the Playlist window (下面的图1). 否则, you’ll have to move the clip to the front of the playlist to make it appear in the Preview window, or use the older controls in the Shot Editor to edit the in and out points.

图1. That’s a playlist on the bottom of the figure; note the useful trim controls on the bottom of the preview window on the upper left.

For live shots in a playlist, right-click to set the duration of the shot. You can do this for VOD clips as well, though trimming in the preview window makes more sense. 剪辑选择之外, you choose the transition to apply to the shots in the playlist via the button on the lower right of the playlist box. 在图1中，选择Cut转换. You can also choose the shot Wirecast transitions to after the playlist finishes, 或者你可以循环播放列表. 此选项对于非工作时间操作很有用.

To queue and take the playlist live, use the normal program controls. 在回放期间, a counter shows you how much time remains in the clip playing and the playlist as a whole. If you need to manually jump from clip to clip within the playlist while it’s playing, 您可以在播放列表中使用箭头控件. Overall, it’s a great addition that virtually all producers will use right away.
