how to re-encode a mpg file to a x times slower ?

[adrianmak]

I have a 1 min mpg clip, I want to re-encode to avi and the key point is to make the avi time length 5 times slower than the original mpg clip, in other words similar as playback in slow motion.

i.e. 1 min mpg clip will become a 5 min avi clip

I read mvflowfps but it's quite complex and I've no idea how to use it.

convertfps or changefps are "simpler" Avisynth functions.

Gee, and I gave you a link to the completed parameterized script. All you needed to do was weed out the trims and replace the AviSource statement. The posts above and below that one discuss the specifics of that particular project if you want more information.

Maybe the simpler convertfps or changefps function will be adequate fior your purposes. At a 5 times slowdown both function as simple frame repeaters.

Even simpler would beSelecetEvery(1, 0, 0, 0, 0, 0).AssumeFPS(Last)which will repeat every frame 5 times.
