ArcMap had functionality to move the observer (camera) along a predefined line/path to create an animation: 'Create Flyby from Path'. ArcGIS Pro lacks this functionality. The same for an object other than the camera (e.g. a car, airplane).
This is implemented in ArcGIS Pro 3.3. See Your Ideas in ArcGIS Pro 3.3 for a full list of all user ideas you can look forward to! And be sure to check out the release blog and what’s new help topic and video to learn more about all the new features and functionality in the release.
