> Tour 3—Publishing Your Screencast
> The purpose of this tour is to familiarize you with publishing your screencast. ScreenFlow screencasts are not video files—they are saved as ScreenFlow documents (with a .screenflow extension), which can only be opened and used by ScreenFlow.
> There are two ways to publish your screencasts—by exporting them to a standard video file format or publishing them directly to an Internet video service, like YouTube or Vimeo.
> Determining the correct export settings for your screencast depends on the complexity of your screencast and the intended use of the video after it has been produced.
> This tour explores the basics of ScreenFlow’s export options. For a comprehensive description, see Publishing Your ScreenFlow Project.
> Select File > Export or press Command-E to export your presentation:
> Figure 14. Export Settings Window
> Save As. Choose a name for your exported video (default: ScreenFlow.mp4).
> Where. Choose a location to export your video.
> Preset. ScreenFlow has several export presets for your convenience. This tour focuses on the most commonly used presets.

> • | Web-High. This is the default export option which encodes using the H.264 codec. It was chosen as the default codec based on both image quality and file size.

> • | Web-Low. This is an export option similar to Web-High, but formatted for a low bandwidth. It plays more smoothly on slow Internet connections but the image quality is not as good as Web-High.

> • | Lossless. This is an uncompressed export format ideal for additional editing. This format has the highest quality image but also the largest file size. When exported at 100%, the image quality is identical to the original recording.

> iPad / iPhone / Apple TV / iPod. These export options are formatted based on the recommended video specifications for these devices. They cannot be altered.
> Dimensions
> These options are used to set the dimensions of your video export. You should not set a size larger that your canvas size. This does not improve image quality.
> Scale by. Use this option to scale your screencast by a percentage value. This is an easy way to shrink your screencast while maintaining the aspect ratio.
> Scale to custom size. Use this option to set the exact width and height of your exported video. Click the Letterbox Content box to add letterboxing to your export.
