Ever since Rebecca explained自从丽贝卡解释 how to create a screencast in OS X如何建立一个screencast在OS X的 , I’ve been messing with Snapz X Pro. ，我一直在食堂与Snapz X专业版。 The only real problem I have with it is that the resulting files (.mov) are huge.唯一真正的问题我已经与它的是，由此产生的文件（ 。传送）是巨大的。 There are a few compression/save as options and I will review them, but I’ve found it much easier to take the resulting files and convert them using ffmpegX, a free audio/video conversion tool.有几个压缩/保存为选择，我会检讨，但我发现更容易采取由此产生的文件并将其转换使用ffmpegX ，自由的音频/视频转换工具。 This tutorial will take you through the steps to convert .mov files to Flash.本教程将采取的步骤操作转换。传送文件到闪存。

- You’ll notice a number of output formats - but none of them are Flash.您会发现一些输出格式-但没有人有闪光。 You can use H.264 for better compression (better than .mov) - but the resulting file can still be too large for web streaming (especially for folks not using a very fast broadband connection).您可以使用的H.264更好的压缩（优于。传送） -但由此产生的文件仍然可以过于庞大的网络流媒体（尤其是人使用的不是非常快宽带连接） 。 Leaving Animation as the default will result in a large file, but that file can be heavily compressed (the point of this tutorial) without much loss in quality.离开动画作为默认将产生一个大的文件，但文件可以大量压缩（点此教程）没有太大的损失质量。
- Return to the Preferences screen, and this time click the Settings button in the Include Microphone Track section. Note: this tutorial assumes you are in fact including audio recorded from your microphone in your screencast.返回到屏幕上的优惠 ，这一次单击设置按钮在麦克风包含田径节。 注：本教程假定您实际上是包括音频记录您的麦克风在您的screencast 。

- Once completed, locate your newly created .flv (flash) file.一旦完成，找到您的新创建的。视频（闪存）文件。 Notice the huge difference in file size (mine went from 43.4MB to 2.5MB).通知的巨大差异，档案大小（雷从43.4MB ，以提供2.5MB ） 。 You can play your flash file in your browser, or a video player like VLC if you have it installed.您可以发挥您的闪存文件在您的浏览器，或视频播放器可变长编码一样，如果你有安装。 Note that the quality will have decreased slightly from the original .mov, but not significantly.请注意，质量将略有下降，从原来的。传送，但不显着。 And the huge decrease in file size more than makes up for the slight quality loss.和巨大的减少文件的大小超过弥补了轻微的质量损失。
