- 1). Go to YouTube and sign in to your account if you have not already done so. Click your username at the top of the screen, and then click "Videos" from the list of options that appears.
- 2). Click the "Video Editor" tab on the page that opens. This takes you to a page that displays thumbnails of all your videos. Find the one you wish to rotate and drag it into the blank rectangle with a video icon below all the thumbnails.
- 3). Hover your cursor over the video thumbnail, where it now appears in the rectangle where you dragged it. Click the "Rotate" icon, which looks like a curved arrow. Click the left or right curved arrows in the new window that opens to rotate your video in the direction of your choice.
- 4). Click "Save" when you've rotated your video to the correct orientation. Click "Publish" in the upper right corner of the video editor to publish your newly rotated video.
