When im going to apply the visual deflicker after the visual previews, i notice that my time lapse video rotates to the opposite direction ( for example, in the original time lapse the sun rises from the left, but after the deflicker the video is rotated and the sun rises from the right). Is this a problem or am i missing something?

Ps: i'm new to this amazing world of time lapses, so if im doing something wrong please feel free to give me some suggestions.[Image: https://forum.lrtimelapse.com/images/icons/biggrin.gif]

So you see the previews mirrored in LRT? This shouldn't have anything to do with deflicker, LRT5 evaluates the rotate information in the metadata and rotates and flips the images in the preview accordingly. They should be displayed exactly as in Lightroom.
If not, let me know which is the camera that you are using?
Which LRTimelape Version are you using?
Do the images have a different orientation in LR and LRT?
