more details of rotating Pans on the dome

As mentioned in my earlier post, I'm using blender to rotate Panoramic images made into fisheye fulldome frames. By trial and error, got some insights on what looks good on our dome. A rotation from -30 degrees to +30 deg in 10 seconds is too fast. A 30 second clip seems desirable, and with only -15 deg to +15 deg of rotation.

For creating keyframes in blender, shortcut key is I (i, not L). In 3D view, select the object by right-clicking, N for numerically entering location/size values, press I after entering the desired values. Move to the next required keyframe, repeat the above. The rotations speed up and slow down at begin and end points by default - some sort of spline for velocity changes. Click on the Start and End frame to edit number of frames.

To delete a keyframe, one way is to go to Dope Sheet view, select the keyframe by right-clicking on it, and hitting the X key, or Key -> Delete Keyframes menu item.
