Premiere Pro produces a 90% size image when video clip is transferred from import to timeline
I processed the same video clip in another package (FILMORA) and there was no size distortion.
I downloaded an earlier version of Premiere Pro and there was no difference in imported video clip and timeline size in the upper right panel.
I, therefore concluded that the recent upgraded Premiere Pro had a "bug."
