Create Transitions

When starting up DVD slideshow GUI will convert all bitmaps/avisynth scripts in the Transitions folder to transitions. So by adding a bitmap/script to this folder and restarting DVD slideshow GUI a new transition will be added to the transition options.

Bitmap transitions

Transitions can be made out of gradient greyscale images going from black to white. You can use the freeware paint programs like Paint.Net or Gimp to make gradients.

Avisynth transitions

Transitions can also be made out of Avisynth scripts. An avisynth script is a txt file with an .avs extension. Open one of the avs files in the Transitions folder to see an example.

The variables which must be used in each script is at, bt and ft.

at is the first clip of the transition
bt is the second clip of the transition
ft is the number of frames

Ex. This is the code from the Wipedown.avs file:

# TransAll avisynth plugin created by V.C.Mohan
TransWipe(at,bt,ft,"down")

See the transall.txt file to look at more examples of different transitions.
