If you use AviSynth in your processes today, all you need do is use the ChangeFPS() filter to replicate frames, followed by AssumeFPS() to reset the frame rate.

Here's an example for a PAL sequence (using 1/3 speed):

ChangeFPS(75) # 3x the frames
AssumeFPS(25) # return to 25 fps

Here's an example for an NTSC sequence (using 1/4 speed):

ChangeFPS(119.88) # 4x the frames
AssumeFPS(29.97) # return to 29.97 fps

This is how I did it, using DGBob, based on some posts by Neuron2.

whvideo=Trim(video,0,678)
videoslow=whvideo.DGBob(order=0,mode=2)
videoslow=videoslow.assumefps(25)

(the 25fps is for PAL which is what I'm creating)

Then I can do things such as join video and videoslow, etc....

Thanks for help,

I think all your help is for DV or AVI format.

What about MPEG-1 format ? What kind of program can be used for direct video slow down ?
