So i straighten up and crop all my photos in lightroom i seved the matadata to files. Export all files in dng, uplode all files in lrt..apparently seems to be all fine..so i continue with all the processing, key frames, lightroom..i reload the files from lightroom and it's all good..then when i go to visual previews and render all the photos twist like it was before. what shold i do, i'm going mad..

Export all files in dng, uplode all files in lrt..

If you export files to DNG, you will be working on different instances of the files in Lightroom and LRTimelapse this won't work.

Please do not export, just work on the same files in Lightroom an LRTimelapse.
