General Information

• How to Uninstall QuickTime Codecs on Mac. There are times you need to uninstall these codecs and get rid of them from QuickTime player. Option 1: Just trash the component file from the /Library/QuickTime folder. It is easy but inconvenient if you want to download, unzip and copy the codecs just trashed.
• Another cause of After Effects and QuickTime failing to communicate is an issue with permissions for files in the After Effects preferences directory. To force After Effects to rebuild the preferences directory and set permissions correctly (as well as reset any corrupt preferences), quit After Effects, remove the following folder, and then.

If you prefer to locate the Unsaved QuickTime file from your Macintosh HD folder in Finder, don’t forget to press Command+Shift+Dot to show you hidden Library folder so that you can find folders like Containers, com.apple.QuickTimePlayerX, Data, Library, Autosave Information step by step.

When upgrading or updating to a newer version of ScreenFlow it is possible that a new version of the Telestream Audio Driver will be included in the new version. The Telestream Audio Driver does not get upgraded automatically when installing the new version of ScreenFlow, but instead is upgraded when the Record Computer Audio is used for the first time after the update of the software.

In some instances after the Upgrade of the driver is complete, the same message displays again when enabling the Computer Audio recording.

Restarting your Mac after Upgrading the Telestream Audio Driver will usually resolve issues with the Upgrade process.
