Re: [DCP-o-matic] How to un-letterbox content with non-square pixels without distortion?

Hmm, I just grabbed some images and checked the pixel dimensions - one thing is a bit weird, QT Player and an exported single image tell me the source pixel dimension is 720*404 (including letterboxing) - yet DCP-o-matic says it's 720*576?

If I strip the letterboxing in Photoshop, the content is 720*319. That's a 1:2.25 AR. Quite common to put side cropped CS images on DVD like this in order to reduce the letter-boxing somewhat. A bit weird, also that DOM is giving the vertical dimension as 576 when it seems to be only 404, but it is still possible to create a proper DCP from it. You just need to acknowledge the necessary letter-boxing. VLC gives dimensions in statistics as 720/576, and extracts/snapshots a 1024/576 still (incl. letterboxing), content stripped from letterboxing is 1024/454. But that is just a different way to apply the anamorphic stretch (horizontal stretch vs. vertical compression). It's both 1:2.25.
