Hello, it happens to me only after updated to the latest v.21 Build 315, current subscriber.
Without tocuhing anything related to pan/crop, one of the tracks (randomly) would appreared zoomed (200%+) in the preview and rendered video. I have no idea what happened to the software and I guess even downgrading the software, I don't think I can open my project in older versions, rendering my current work uselss.
Has anyone faced this issue before and has a solution? Thank you.
