I have been trying to export the video only--I don't need all the images to export as well. I am very new at this. Is there something I need to be doing. I have tried several times from LightRoom but it continues to give me all the images as well and I only want the video to be exported. Any ideas? Thank you.

It's not possible. LRTimelapse needs the intermediary sequence to be able to create video from it. But you can set the render dialog in LRTimelapse to remove the intermediary images after rendering the video.

Thank you Gunther. I just bought your ebook so that should help. Looking forward to it.
