Maybe you have captured a video with your cellphone or camcorder and when you try to play it in your computer, you discover that it is rotated 90 degrees. This error happens because many cellphones don't understand the orientation.
When you have a rotated video, you can use two free programs to rotate and save you video in the orientation you want: VLC Media Player and Windows Live Movie Maker. This tutorial guides you on how to use VLC Media Player to rotate and save your videos.
Attention: After you rotate and save your videos, you must reset VLC player to it's default settings , by going to: "Tools" > "Preferences" and press the "Reset Preferences" button at the bottom side of Preferences window.
1. First download and install VLC Media Player from here : http://www.videolan.org/
2. Then choose your rotated video from your computer and "right click" to open it with VLC Media Player
3. In the VLC Media Player main menu go "Tools" > "Effects and Filters"
4. In "Adjustments and Effects" window, choose the "Video Effects" tab
5. In "Video Effects" tab, choose "Geometry"
6. In "Geometry" click the "Transform" box to enable transform and make sure that the "Rotate by 90 degrees" setting below is selected. Then choose "Close" to close the window. Notice*: The "Rotate by 90 degrees" setting, rotates your video by 90 degrees clockwise. If you want to rotate your video in a different angle then choose the corresponding angle.
Now you can view and play your rotated video with VLC Media player (only) in the right angle. 7. If you like to save your recent rotated video, from the main menu go to "Tools" > "Preferences"
