Is there a way to access the Render dialog without a fresh Export?  I exported and rendered a timelapse video, and decided to change one of the render settings, but had to wait for an hour while Lightroom re-exported before I could get into the Render dialog.  Am I missing a back door to the Render mode?

Thanks

Just go to "File/Render Video" in LRTimelapse, select the intermediary sequence you want to rerender, set your settings and go!
