How do you rotate a video?

How can I rotate a video?

  • I just recorded a video on my phone, but when I play it on my Mac it's in the wrong orientation. How can I rotate the video by 90 degrees so that I can upload it to youtube? Free solutions are preferred. I just found out how to do it using YouTube's Video Editor which has rotate left/right buttons. But this is not an answer how to rotate on Mac.

  • Answer:

    You can use MPEG Stream Clip: http://www.squared5.com/svideo/mpeg-streamclip-mac.html Simply open the file and choose to export it from the file menu in a format of your choosing, selecting the appropriate rotation in the selection box. You can find out the current format of the video by choosing File > Show Stream Info as to match the export to the input settings if required.

Use QuickTime to Rotate Videos You don't need to use any 3rd party tools to do this. It's built right in to QuickTime Player. Any file that can be opened in QuickTime can be rotated by choosing Edit > Rotate Left (or Right) or by typing Command-Shift-L / R. If you alter a movie file in this way and attempt to close the file (Command-W) you will be prompted to save your changes. Save them to a new file and you will have a newly rotated video. Share your Video on YouTube with QuickTime QuickTime also has a built-in way to share your video on YouTube. With the video open (and correctly rotated now) select Share > YouTube...

Using ffmpeg you have a few techniques: ffmpeg -i in.avi -vf "transpose=1" out.avi ffmpeg -vfilters "rotate=90" -i input.mp4 output.mp4 You might need to build a recent version from source to get some of those options to work. Using mencoder: mencoder -oac copy -ovc lavc -vf rotate=1 original.mp4 -o 90_CW_rotated.mp4 mencoder -oac copy -ovc lavc -vf rotate=2 original.mp4 -o 90_CCW_rotated.mp4 Sources: http://stackoverflow.com/questions/2208522/ffmpeg-on-iphone-modifying-video-orientation, http://superuser.com/questions/162259/ffmpeg-rotate-mp4-90

Use the ⌘ Cmd+Shift+L, R, etc. when you open the video in Quicktime. That should do the trick.

Just open QT and it automatically rotates it. Then simply export it.
