How to: Reversed Video Clip

As we head deeper into our film productions, I wanted to create a scene where after I got out of my house, my television turn on by itself and there came a “TV static poltergeist” type of effect. While browsing at youtube.com, I came across this clip.



This is perfect for the opening of the “TV static poltergeist” scene but then the closing is far too short if I used the closing in the above clip. And so I use the “TV turned on” effect for the closing of television as well.So I head over to the net and look for a software to reverse video frame. Eventually I came across AviSynth. It has a function which I needed and that is the Reverse filter.

But how did I do it?
Well to start off, you need to download 2 video tool. After the installation, open your notepad and type:
AviSource("C:\MyVideoClip.avi")
Reverse()
Note: Replace the directory address to where your video clip is located.

Now choose “Save As”. In the prompt box, select “All Type” in the “Save As Type” and save it as a file name under the extension *.AVS (eg: myclip.avs).
Next… run VirtualDub and drag you *.avs file into the program.

If you have not realized it yet, the video clip is reversed.

All you need to do now is save that file.

On a certain note, when you run you saved clip, the audio is either reversed or there is no sound at all.
And so I used VirtualDub to extract the un-reversed audio and attached it to the Reversed Video Clip.
