Follow these simple steps to get your first result within minutes:
Step 1: Insert keyframes
- First, select the default Camera in the Object List.
 - Move and rotate the camera and click Animate > Insert keyframe (shortcut: I) to define the start of the video.
 - Next, drag the red timeline indicator a few seconds to the right, move the camera, and insert a new keyframe.
 - Optionally, repeat the previous task as many times as you like.
 
Step 2: Preview & render video
- Adjust the green animation range so that it covers all keyframes.
 - Drag the timeline indicator to the start of the timeline and click 
 (shortcut: space) to preview the video.  - Move keyframes apart from each other to slow down the camera movement, and move them closer to each other to speed it up.
 - When you are done, drag the timeline indicator back to the beginning and press Export to launch the Render Video window.
 - To export the video, stick with the default presets and press Render.
