A simple duplicate for every frame?

[Atlantis]

I have a 15fps clip. I want to duplicate each frame and obtain a 30fps clip with the same duration? How can I do this in avisynth? Doubleweave doesn’t work, because it makes interlaced frames from my 15fps progressive frames. That’s not what I want! A simple duplicate for every frame.

Here's a simple way:

clip=AVISource("movie.avi")
Interleave(clip,clip)

Thanks! But when I use it and process the avs file in VirtualDub, at the very end, VD crashes. I have to use premiere to make an intermediate 30 fps avi file.

I have sometimes used the following sequence to avoid having vdub read off the end of a file when DirectShowSource reports the wrong frame count.

video=DirectShowSource("D:\Buffy\Whatever.vob")
blanks=BlankClip(video,300)
trim(video+blanks,0,video.framecount+100)
