It seems to me that whatever type of option I pick to render the video with LRtimelapse, I get a blurry effect of ghost, like this :

From my experience this is due to a resampling of the images, desactivating should make it work, but there are no options for that
what could I do please ? 
I tryed all different framerate and different options, it is still the same.
Thank you for your help

This is the "Motion Blur Plus" option in the LRTimelapse Render dialog.
You should deactivate that when rendering sequences with fast pans or zooms.

Thank you for quick answer
am gonna try it out. Oh while I got you I think an option to add LUT file at the rednering process, it would be really awesome, and also some presets for encoding to vimeo and or youtube, that would be cool (I know it might make it look more complicated, but I would find it super usefull)

Yes it works thank you, why did you do it like this ? Why it is not like the motion blur from After effects ?

Any frame blending algorithm will do basically the same, if it doesn't interpolate. And interpolation might lead to other weird effects.
