I took a few videos on a new Lumix camera recently (format *.MTS) and I’d like to rotate them 90 degs counterclockwise, as I took them holding the camera in portrait at the time, but would like to view them on screen in portrait as they should be.
I’ve googled this a bit, and downloaded a few options. Picasa seemed to be the easy answer, but doesn’t (that I can see) support this file format (and even if it did I’ve read that it messes up the audio too) and all other programs I’ve tried have either watermarks on the output video or annoying malware-esque extras attached, and I’ve spent the last hour clearing their aftermath off my computer. And they didn’t work, to add additional insult.
Does anyone have a simple solution? It’s a common format, so I assumed it would be an easy win, but am coming up short. Many thanks for any assistance you can offer.
