LRTimelapse 5.0.8 and Lightroom 7.4 on MacOS 10.13.6

I edit 3 keyframes, select them in grid mode and write the metadata to files. When I reload in LRTimelapse the keyframes are displayed upsidedown. All other frames are displayed correctly. Any ideas what is going on?

Thanks.

Which files are those? Which camera?

The camera used was an iPad Pro 12.9" using ProCam 5 app in raw mode (files generated are 12 MP DNG files). The edits that I applied in Lightroom to the 3 keyframes were to select and Adobe profile (one of the modern profiles from the default set shipped with Lightroom), apply auto tone, and some additional tweaks to the exposure setting. When I view each of the keyframes in LRTimelapse the 3 keyframes appear upsidedown.

This might be a problem with those dng files. I'd suggest to ignore it. You can just rotate them back in LR. Check out, if after the auto transition in LRT and coming back to LR after reading metadata the other images are flipped too. In that case it might make sense to do the manual flipping back only at the very end before rendering.
