fixed : quickly rotate a movie file in macOS 10.15 Catalina

Question :

I have a movie-file that was shot on an iPhone in portrait-mode, but I think it will look better  when viewed in landscape-mode. It’s a video of you cat playing on the carpet, shot from above, so both portrait-mode and landscape-mode are okay for viewing, but as we prefer to view video’s on out TV it would make more sense to have it in landscape-mode.

How do I do that ?

 

Answer :

In MacOSX and OSX rotating photos was easily done in iPhoto or Photos.app, but rotating video couldn’t be done in iPhoto or Photos.app – that had to be done in video editing software like iMovie, or a dedicated video-rotation-app.

In macOS 10.15 Catalina, rotating video 90 degrees can be done extremely simple in the Finder :

  • open the Finder (click out of all apps until you have only the Desktop to look at)
  • open a New Finder Window by typing CMD and N keys on your keyboard simultaneously (or goto Finder > File > New Finder Window)
  • locate the video-file (if you know it’s name, typ it in the Search-bar, else browse to the file if you know where it’s located)
  • then click on the file name to select it
  • the video preview will now come up on the right side, with various info and some buttons below it
  • to rotate your video 90 degrees counter-clockwise, click on Rotate Left
  • to rotate your video 90 degrees clockwise, press the ALT key on your keybord and click on Rotate Right (in the same spot where the Rotate Left button used to be)
  • then wait for the processing to end…

…and you’re done 😉

That’s it – enjoy !

tip : easily make FREE screen recordings in MacOSX

“Screen Recording” means making a video of your screen (i.e. your MacOSX Desktop) while you are using it.

This is a way to make tutorial video’s which you can use to send or give to others, just like the ones you find on YouTube.

(…or you can use this to record online video’s that you can not download)

“Screen Recording” used to be something that would require rather expensive software, but with the introduction of QuickTime X Player in OSX 10.6 Snow Leopard, it’s a simple and completely FREE feature included in MacOSX !

Here’s how to :

– open the “QuickTime Player” application (or maybe it’s called “QuickTime X Player” in your case)

– go to “File” and select “New Screen Recording” from the pulldown menu – or use the key-combo [SHIFT]+[CMD]+[N]

– in the small (shaded) screen that appears, you will see a record-button (with a red dot) in the middle and a grey triangle button on the right

– click on the grey triangle button and you can select your audio input source (e.g. a microphone you’ll be using for your voice-over comments), output video quality and whether you want record your mouse movements and clicks in the video also

– then click on the red-dotted record-button to start recording, but when you do so you will get the option to either select a (static) part of the screen [by dragging the cursor over the area you want to select for recording] or the entire screen [by clicking anywhere on the screen]

– recording will start right away after you’ve made your choice (so do not forget to start talking if you want a voice-over)

– to stop recording, go back to the record-button (which now shows a small black square) and click it

– the recording will stop and it will take a few moments for QuickTime X Player to process it (the longer your recorded, the more time the processing will take)

– the recording will be visible in a QuickTime X Player window right away

– to Save or Share your screen recording, go “File” and choose one of the following :

option 1. “Export” (= normal Save) for saving as a QuickTime .mov-file [you can set the video quality from the “Format” pulldown menu ; either (general) Movie, 480p, 720p or iPhone/iPad/AppleTV ready

option 2. “Export to” to directly upload to a website, import into iTunes or edit in iMovie

option 3. “Share” to directly share your screen recording with your friends through eMail, iMessage (= Apple SMS), AirDrop (= Apple WiFi-filesharing), Facebook, YouTube, Vimeo or Flickr

That’s it ; this might seem rather complicated from these instructions, but it’s actually really simple once you try 😉
