How to Reverse Video Clips

To reverse video, you need a video editor, VirtualDub and AVIsynth which works as a frameserver, providing instant editing without the need for temporary files. Here we are to reverse an avi video.

1. Download VirtualDub and AVIsynth
   
2. Install AviSynth.
   
   
3. First, you need to create a simple text document with special commands, called a script. Open Notepad, or any other text editor, enter the command below:
   
   Reverse(AVISource("C:\video file.avi"))
   
   For example, you have stored a video file named "The Lord of Ring.avi" on disk D, then you should enter a command in the Notepad like this:
   
   
4. Save the notepad file with .avs as the file extension. Name the avs file and find a folder to save it.
   
   
   
5. Extract the VirtualDUB package to a location on your hard drive. It usually does not come with an installer, so run the VirtualDub.exe program from the directory you just extracted it to.
   
6. Drag and drop the avs file onto the application window.
   
   
7. Choose Save as AVI in File menu.
8. VitrualDUB begins to convert the avi video.
   
   After reverse, you can play the movie from end to start.
   
9. For all non-AVI formats, eg, wmv video, you need to create an AVIsynth scripts including frame rate of the video in order for VirtualDub to properly open the video file.
   
   Reverse(DirectShowSource("C:\file.wmv", 29.97))
   
   29.97 is the frame rate of the video in order for VirtualDub to properly open the video file. 29.97 in this example is the most common NTSC frame rate. Other common frame rates include 23.976, 25, and 59.94. Save the notepad file with .avs as the file extension.
