I just came across a smartphone video that could not be successfully rotated and scaled in 2.14.59. I then suggested to try 2.16, and while it was possible there with a custom scaling aspect ratio ( 1/1.78), it is obvious that DCP-o-matic handles vertical/90degree flagged video in the wrong way.

DCP-o-matic detects the 90 degree flag and rotates the file correctly, but then applies the wrong aspect ratio of the original format, but not the rotated version. That is - the vertical video is always stretched out horizontally. In DCP-o-matic 2.14.59, I could no nothing to correct this (1.19 was the smallest AR). In 2.16.x, I was at least able to apply a custom 0.56:1 aspect ratio to the 1.78:1 vertical video.

I was able to correct the issue by exporting the original smartphone video using QT to a new 1080p quicktime movie. That obviously removed the rotation and the 90 degree flag and created a standard 1080*1920 video, which both DCP-o-matic 2.14.59 and 2.16 handled correctly.

It's not a huge deal, but I see a lot of directors or actors greetings recorded with smartphones for festivals now that often get transmitted last minute, and it would be nice if DCP-o-matic could handle them properly.

Do you need a sample, Carl?
