Create a Black Video

[ssaga]

How can I create a whole black video with virtualdub? I tried to load a bmp and turn the brightness to 0, but can't adjust the time. I know it's possible to load another movie and turn the brightness down to create such a movie, but it's too slow. Can anyone tell me a good way to create one?

IIRC Avisynth has a "Blackness" command.

create an avisynth script that would determine the duration of a black.bmp to your desire and build it through virtualdub

The following Avisynth script should do

BlankClip(length=300, width=640, height=480, fps=30)

Type that into Notepad, change the parameters to what you want, save it to a .avs file and open it in VDub.
