1. Here's how

Lumion 8.0 and newer renders Photos, Movies and Image Sequences in the background, so that you can check your emails etc while it is rendering.

• We recommend rendering .MP4 files to a folder on your local harddrive.
• Please do not render the .MP4 file to a cloud back-up folder such as DropBox.
• When the render process is complete you can move the .MP4 file to the desired folder.

If your PC switches to the Windows login screen after a few minutes, rendering will also be interrupted. You can prevent this from happening by running the Windows Media Player in the background, e.g. with playback of a few songs set to repeat.
