Switching SOLIDWORKS animation cameras gives more control over location, target, field of view, etc. You can place keys and edit the camera at various positions to change the orientation and zoom.
If you have more than one camera, you are able to switch between them during the animation. First set up the cameras and place keys to indicate start and end settings of each by editing the cameras along the timebar.
Then select a camera to use at T=0s. Right-click on the key beside ‘Orientation and Camera Views‘ and select ‘Camera View‘.
The pop-up will allow you to select the camera to use from the start of the animation.
Then you can place another key along the timebar beside ‘Orientation and Camera View’ to select a different camera.
The pop-up will appear again and you can select a different camera to use, in this case Camera2 is selected:
An example animation switching between two cameras is shown below:
