Can I rotate a movie shot with portrait orientation (!) but plays as landscape?

[BudVitoff]

Some time in the past I came across an app that would do just that, but it has disappeared. (I have no idea why people shoot movies vertically. Have they ever been to a theater that projected that way?) I'd appreciate it if someone could refresh my memory as to the name of that package.

You can change the orientation in iMovie. https://support.apple.com/kb/ph2234?locale=en_GB

Alternatively, there's an app mentioned here:

You can rotate a movie with Quicktime.

I shoulda stayed in bed.

You're right, QuickTime did the rotation just fine, but I don't think I'm going to keep it in my Windows system. Note the following:

"The U.S. Department of Homeland Security has sent out an urgent alert advising Windows users to uninstall Apple's QuickTime program, the video and audio software (once) widely used to play movie trailers and other Internet media clips, due to two major vulnerabilities in the program that can allow hackers into people's computers. QuickTime for Windows will continue to work and is still available for download, but Apple and the DHS have urged Windows users to uninstall the program.​​​​"
