MOV from iPhone imports in 'vertical' aspect

I'm puzzled why my iPhone 6S+ records movies like this example in vertical mode.

The iPhone app that recorded it (Motion Sensor), is presumably the root cause, because MediaInfo shows that it is indeed 1080x1920.

Extract from MediaInfo

Format profile                           : High@L4

Rotation                                 : 270°

Yet all the other video players I've tried (WMP, MPC-HC, VLC, PotPlayer, etc) are smart enough to play it correctly in landscape mode. But not MEPP 2016. After a -90 rotation it then needs resizing to fill the screen, two unwanted extra steps.

How does it appear when imported in other users' versions of MEPP please?

Hi Terry

Vertical as you have found.

IIRC from previous topics on this issue, the conclusion was MEP ignores the rotation flag in the video file metadata.

Hi Terry,

I'd blame it on the cat.

Since it was shot with the iPhone in landscape, then the last line Media Info showing a rotation of 270 would put it vertically, no?

I opened it in VPX and MEP2019 and it came in vertically. I flipped it 90 counterclockwise and didn't have to resize the image; it filled the screen.

It probably has something to do with compensating for all of those iPhone users who film in portrait mode. The program or iPhone couldn't believe that someone would actually film in landscape mode.

Thanks both.

John EB: I’m sure you’re right about the rotation flag and I now recall that earlier discussion. Shame Magix still haven’t got around to a presumably trivial bit of coding like the other video player developers.

Did it automatically resize after the manual rotation, as in John CB’s case?

John CB: I blame the few spoons of canned red salmon, the only ‘bait’ I had at hand in my quest - for a fox not a cat!

No, it centred itself with a resolution of width of 1080, height of 608. Checked this several times.

Terry you have some very spoiled foxes, and cat, was it 'the best' salmon?

Thanks, interesting video. But my wife doesn’t even know about the tinned salmon so I’ll have to draw the line at stringing up a dead rabbit!😊
