I shot my video vertically with a7iii for IG story. When I rotate the clips 90degree in Premiere to do the edit (cos original comes in landscape), playback becomes laggy and not editable. Is this normal that Premiere can't handle such edit? If I render preview all is ok but I have long footage. It takes hours to render the entire thing before I even start editing.
Is there other way to edit in vertical mode without compromising the playback?
It seems not to have issue with smart phone vertical video which is already imported as vertical mode. Only when I use a7iii footage which comes in landscape mode and I apply rotate, everything goes wrong. Thank you for the help for this one!
