The release of macOS 10.14 Mojave broke all video and image capture functions in Logger Pro. It is still possible to analyze existing videos and photos, but not to capture new content directly with Logger Pro. Logger Pro 3.16 removed all capture features.

You can still capture videos or still images while using macOS 10.14 or 10.15 Catalina.
Instead of using Logger Pro to capture video, we suggest using the app Quicktime Player, included with the operating system. Quicktime Player will perform video capture from a variety of attached cameras, including built-in web cameras. Quicktime Player allows you to trim captured video and then save it to a file. Once saved, insert the video in a Logger Pro session for video analysis.

Another option is to use a camera independently of your computer. Most digital still cameras capture excellent videos. Transfer the video file from the camera’s storage card to your computer, and insert into Logger Pro.

The camera on a phone or tablet is another option. If you use an iPhone, take care to use the “more compatible” format in Settings>Camera>Formats in order to create a video that can be opened in Logger Pro. See Why does a video captured on an iOS device give a codec error or render as a gray or black box in Logger Pro, Graphical Analysis Pro, or Vernier Video Analysis? for more information on this.

How do I collect good videos for analysis in Vernier Video Analysis, Video Physics or Logger Pro?
