How do I cycle through the camera views?

Question

When reviewing the existing cameras of a scene, is there a way to quickly cycle through the views of all cameras?

Answer 1

You can try by binding the cameras to the markers. In the timeline, press M to add marker in specified frames. You can rename that frame by pressing Ctrl + M.

Assuming you have 2 cameras on viewport, then add two marker on timeline (adjust location of the marker diferently, ie : marker 1 : 1-20, marker 2 : 21-50). Now select the first camera, press Ctrl + 0 to set as active camera, make sure first marker selected, then in timeline press Ctrl + B to bind active camera to first marker.

Select the second marker, then set second camera as active again Ctrl + 0, hover the mouse on the timeline and press Ctrl + B.

Now, when you start the animation Alt + A, the camera should switch between first and second based on marker position.

run the following script:

import bpy

scene = bpy.context.scene
currentcam = bpy.context.scene.camera
setcam = False

for ob in scene.objects:
    if ob.type == 'CAMERA':
        if ob == currentcam:
            setcam = True
        elif setcam:
            bpy.context.scene.camera = ob
            break

if currentcam == bpy.context.scene.camera:      
    for ob in scene.objects:
        if ob.type == 'CAMERA':
            bpy.context.scene.camera = ob
            break
