Title: Portrait videos
Post by: Alan Clifford on February 09, 2014, 09:19:10 PM
I took a couple of videos today on the Fuji XF1, probably the first I've done.  And I took one in portrait orientation.  Afterwards, my heart sank as I realized I'd have to try and remember how to rotate it.   But no, various software displayed it correctly.

Intrigued, I looked at the meta data, and even compared a portrait and a landscape, and found a composite tag with a "rotation 90".  But no real tag to show the difference.

How do you do this Phil?  Obviously I'm impressed but intrigued as well.

Hi Alan,

The Composite tags documentation (https://exiftool.org/TagNames/Composite.html) tells you what tags this is derived from.  To see the full details, see the CalcRotation subroutine in the QuickTime module (http://cpansearch.perl.org/src/EXIFTOOL/Image-ExifTool-9.46/lib/Image/ExifTool/QuickTime.pm).
