> Advanced Pane
> The Advanced pane (Figure 82) provides ScreenFlow settings for video magnification, compression, and managing your audio driver and scratch disk.
> Figure 82. Preferences Advanced Pane
> These preferences are described in Table 27.

> Table 27. Preferences Advanced Options
> Preference | Description
> Video Magnification | Select Smooth | Sharp to set the compression algorithm used when computing a scale effect or zoomed callout. Smooth blurs color values to create a smoother transition. Sharp does not blur color values. Default: Smooth.
> Screen Recording Compression | Select Adaptive | Lossless to specify the method of compression used. Adaptive is compressed, which minimizes file size, but the loss in video quality is not noticeable to most users. Lossless is uncompressed which captures all pixels, thereby resulting in a larger file size. Default: Adaptive.
> Computer Audio | Click to install or uninstall ScreenFlow’s computer audio driver, which is required for recording computer audio. Note: If you purchased ScreenFlow through the App Store, the computer audio driver is installed automatically.
> Capture Scratch Disk | Click Change to specify a directory where ScreenFlow can temporarily save media as it is being recorded. By default, this is set to a private system location. Specifying a custom scratch disk allows you to locate your recording in the event that it was interrupted before completion.
