这是一款Mac平台的支持双屏的专业演示工具，能够方便双屏用户进行双屏演示，比如，一个大屏幕显示歌词，而舞台上在现场演唱歌曲。 根据观众的反应，乐队领唱者也许选择唱另一首歌，或者尽早结束歌曲，或者重覆合唱多次。 典型地，这些歌词将通过一些线性播放的幻灯片软件来显示，但由于这些软件无法根据具体的歌曲进行歌词显示，有限的灵活性使它们非常不得人心。而 ProPresenter可以允许程序操作者点击“Control Panel”上的一张幻灯片， 而此时，放映机屏幕将立刻显示新的幻灯片
ProPresenter is a presentation system that utilizes two screens, empowering users to quickly and easily present slides on one screen, while controlling the presentation with another screen. For example, churches that display song lyrics on a big screen while a song is being performed live on stage can dynamically change the slide order for a worship song. Depending on the reaction of the audience, the band leader may choose to sing another verse, end the song early, or repeat the chorus several times. Typically these lyrics are presented through linear slide shows, but the limited flexibility of these programs make them very unpopular because of their inability to function dynamically. Our program allows an operator to click on a slide in our "Control Panel", at which point the projector screen immediately transitions to the new slide. What's more, the program supports QuickTime, and can synch slides with an audio track for canned music presentations. ProPresenter also allows you to change your backgrounds dynamically and, of course, you can integrate ProPresenter with your video production system to key the words over live or recorded video.
ProPresenter 5 continues to build on improvements made in each OS and requires more horsepower to accomplish all that it is capable of doing. Therefore, the system requirements may be a little higher than your existing equipment and are outlined below for both platforms. While the software may work on systems that do not meet these requirements, those systems will not be supported. As always, you will be able to download the software at no charge to test performance on any computer before making a purchase.
ProPresenter version 5.1 (minimum Mac specifications)
Processor: 2.4 GHz Intel Core 2 Duo processor or better

Here is [k]ed version without nag window time bomb and watermarks. Still shows 'unregistered' but just don't mind
