ScreenFlow User Guide
The Advanced pane (Figure86) provides ScreenFlow settings for video magnification,
compression, and managing your audio driver and scratch disk.
Figure 86. Preferences Advanced Pane
These preferences are described in Table27.
Table 27. Preferences Advanced Options
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.
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.
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.
