What do you mean by joining 2 files? If you want a .dream that has two animated wallpapers together you would have to do it with the original video files.
Yes, an animated wallpaper ('.dream'?) with two or more wallpapers together. The original video files have different attributes and every video editor requires the files to have the same attributes for joining. I found one that will permit joining files of different attributes but the quality of the results were below the originals. thx for the reply.
An acceptable alternative would be the 'random background' feature. Unfortunately the 'time' restriction is a problem for me. Many of the videos that I want to link are of various lengths. It would be desired if the code would permit each 'dream' to run it's full length. I am using ver. 3.5.
