Does anyone know of a program that will allow me to put a 1 second black screen at the beginning and at the end of a DVD scene as it is being encoded?

Right now im basically just starting and ending the 'actual' scene with no type of transition to let the surfer know the vid is starting or ending but im wanting to have a second or two of dark screen to signal the start and end of each scene to make them more 'friendly' in terms of letting the surfer know primarily when they are ending.

Any of you folks that deal with movie content know of a program that will let me do this?

Regards,

Lee
