Hello,
as I have seen, there are many filters which enlarge the quality of a avi file.
I am looking for a filter who does the opposite :
I want to make a film which looks "old", like as if I have a celloid film (Super 8) with crackles and dust. Does anyone know whether such a filter already exists and where I can download it ?
Thank you very much. |

Thank you very much for the answer, indeed I found two topics. The problem is, that the first one has no (good) answer. The second one has
a link, which does not work. So I am still searching.....

i was once trying to achieve something similar to what are trying to do. with a little help from this board, i came up with functions that would do sort of random luminance flickering and slight defocusing. adds a lot to the old-ish flair of footage.
i could post these, if you're interested. |

ok, sorry for the delay. here ya go (pls keep in mind that this is neither optimized nor debugged in any way ahatsoever):
| CODE |
function luminanceFlicker(clip c, int amount){
return Layer(c, convertToRGB(UniformNoise(c, ya=200, yb=250, fast=true, width=2, height=2).pointresize(8,8).crop(0,0,4,4).pointresize(c.width,c.height)), "subtract", amount, use_chroma=true)
}
function focusFlicker(clip c, int blur, int intensity){
noise= convertToRGB(UniformNoise(c, ya=100, yb=250, fast=true, width=2, height=2).pointresize(8,8).crop(0,0,4,4).pointresize(c.width,c.height))
blurred= mask(lanczosResize(lanczosResize(c, c.width/blur, c.height/blur), c.width, c.height), noise)
return Layer(c, blurred, "add", intensity, use_chroma=true)
}
