Now that I pretty much memorized the reference manual, I don't think I'll be asking any more questions about AVISynth...

thanks kwag.

Now I'm going to be asking you questions when I get my DigiCam :lol:

Alvinator,

Can I get your current avs script. I am trying to do about the same thing you are but I am not getting good results. I have tried some of the deinterlacers out there. decomb.dll FieldDeinterlace() with not so good results. Any help would be great.

Moat: I replied to your PM.

Very interesting!

Congrats to the whole KVCD community, specially to KWAG, great work!
This is my first post!

@Alvinator:

Could you post the AVS script to do that, I´m trying to do the same but im not getting good results, the video plays unsmootly, as if it had missing frames or something wrong... Thanks in advance

Converting to 24fps worthing the effort?

Hi,

Just a question related with the framerate conversion and avisynth scripts..

It worth the effort to convert from 29.97 to 24 fps in order to make my resulting project smaller using the NTSCFilm KVCD templates?

Regards to everyone,

Convert 60i to 24p

Now it's very easy :cool:
http://home.arcor.de/scharfis_brain/60ito24p.html

Code:

function convert60ito24p (clip video, int mode, int offset)

{

        work = assumefieldbased(video)



        out =(mode==3) ? interleave(

                          \selectevery(

                            \layer(trim(work, 1, 0), 

                              \layer(work, trim(work, 2, 0), "fast"),

                            \"fast"), 5, 0 + offset), 

                          \selectevery(

                            \layer(

                              \layer(work, trim(work, 3, 0),"fast"),

                              \layer(trim(work, 2, 0), trim(work, 1, 0),"fast"),

                                \level = 170), 5, 2 + offset)) : 



        \    (mode==2) ? interleave(

                          \selectevery(

                            \layer(trim(work, 1, 0), 

                              \layer(work, trim(work, 2, 0), "fast"),

                            \"fast"), 5, 0 + offset), 

                          \selectevery(

                            \layer(work, trim(work, 1, 0), "fast"), 5, 3 + offset)) : 



        \    (mode==1) ? interleave(

                         \selectevery(trim(work, 1, 0), 5, 0 + offset), 

                         \selectevery(layer(work, trim(work, 1, 0), "fast"), 5, 3 + offset)) :



        \    (mode==0) ? selectevery(work, 5, 1 + offset, 4 + offset) : work



        assumeframebased(out)

}



# usage: 

#        import (convert60ito24p.avs)

#        loadplugin(your 60fps deinterlacer like dgbob or tomsbob)

#        xxxsource("clip")

#        your60fpsdeinterlacer()

#        convert60ito24p(2,0)



# mode - parameter:

#------------------

# 0 uses simple 24 out of 60 selection -> jerky motion

#

# A B C D E F G H I J K L M N O P Q R    <- input sequence

#   |     |   |     |   |     |   |      <- | = direct copy

#   1    2    3    4    5    6    7      <- resulting output sequence

#

# 1 introduces a blending of every other frame from its nearest neighbors

#

# A B C D E F G H I J K L M N O P Q R    <- input sequence

#   |   \ /   |   \ /   |   \ /   |      <- | = direct copy ; \ / = 50:50 blending

#   1    2    3    4    5    6    7      <- resulting output sequence

#

# this mode delivers a non-jerky motion and should be used with shutter speeds below 1/60sec!

# ie. 1/120 or shorter

#

# 2 uses blening on every frame like this:

#

# A B C D E F G H I J K L M N O P Q R    <- input sequence

#  \|/  \ /  \|/  \ /  \|/  \ /  \|/     <- \|/ = 25:50:25 blending ; \ / = 50:50 blending

#   1    2    3    4    5    6    7      <- resulting output sequence

#

# mode 2 is ideal for shutter speed of 1/60 sec 

# since it simulates very close the 24p (1/24sec) motion blur

# and thus giving a really smooth 24p - motion

# as a positive side-effect, this mode reduces noise and nearly comletely 

# eliminates remained line flickering of the deinterlacing!

#

# every other number given to mode delivers the the input directly to the output (60fps)



# offset - parameter:

#--------------------

# here you can apply a offset for selecting the 2 out of 5 frames - pattern.
