I will go in details.
I got this 6 second video that was taken vertically with the phone.
Put some music, and a PNG Track motion for something.
In the preview its doing its job alright. Moving to the right way inside the borders etc.
Rendering... whenever I render the video though, the PNG goes outside of the vertical area. Outside of the border. like it is re-positioning itself .
The only way i came close to a fix, is... " Render options --> Stretch video to fill output frame size( Do not letterbox) "
Which.. doesn't re-position the track motion png thing, but it ruins the video with stretching it ,as the option is about.
the "Match project Settings" is nonsense , since it matches me with Audio rendering options only!
Thanks a lot for taking your time ^^. Have a good day!
