AviSynth Script for Motion Interpolation

[elyts]

Hey guys,

is it possible to use the following script to double up the framerate of a videofile in the PMS?
When i copied this following script in the AviSynth script section, it tells me that the data is corrupted.

That is the script:


SetMemoryMax(1080)
SetMTMode(3,8)
ffdShow_source()
SetMTMode(2)
#change pel=1 to pel=2 if you have enough power left; however max CPU load should not exceed 75%;
super=MSuper(pel=1, hpad=16, vpad=8)
#change searchparam=1 to 2 or 3 if you have no artifacts; The higher the number, the smoother it is;
backward_1=MAnalyse(super, chroma=false, isb=true, blksize=32, blksizev=16, searchparam=1, search=3, badrange=(-24))
forward_1=MAnalyse(super, chroma=false, isb=false, blksize=32, blksizev=16, searchparam=1, search=3, badrange=(-24))
backward_2 = MRecalculate(super, chroma=false, backward_1, blksize=16, blksizev=8, searchparam=1, search=3)
forward_2 = MRecalculate(super, chroma=false, forward_1, blksize=16, blksizev=8, searchparam=1, search=3)
MBlockFps(super, backward_2, forward_2, num=50, den=1, mode=2)
SetMTMode(1)
GetMTMode(false) > 0 ? distributor() : last

Use of AviSynth isn't really recommended. I think it would be better to figure out why you want to double the framerate (or convert to 50FPS) and try to find a workable solution with MEncoder before going back to AviSynth.

Its like an alternative to TrueMotion that is built in in newer TVs. My TV doesn't have this function. I tested the script on my computer and the videos look amazingly smooth. Converting is not an option for me, because it takes too much time.

Is it possible to use just Mencoder with 10-bit videos? I thought you had to use Avisynth/Mencoder or FFMpeg/Mencoder with those.

if found another post on the forum which is about the same problem.
viewtopic.php?f=6&t=6091

the script used there differs from the one i posted(mvtools2 is used in the script i posted and it should play 24fps videos with 50fps, not 48).
i tested it and i can watch the video, but there is no change in the fps. even though, when i put this script into ffmpeg's avisynth tab on my computer, it works perfectly.

why exactly isnt it recommended to use avisynth in ps3 media? and is there a possibility to realize something like this in PMS?

Yeah AviSynth isn't recommended as much as MEncoder but it would be cool to add this feature. I have been thinking of adding an option called true motion or something for a while. I'll look at it

[elyts]

Nice, tell me if there is any progress Maybe it is possible to realize this feature with MEncoder itself

The following script seems to work, if I add

framerate == 23.976 :: -ofps 50 -mt -lavdopts threads=4

to the MEncoder Expert-Settings. But the video stutters like sh**.

#AviSynth script is now fully customisable !
#You must use the following variables ("clip" being the avisynth variable of the movie):
#<movie>: insert the complete DirectShowSource instruction [ clip=DirectShowSource(movie, convertfps) ]
#<sub>: insert the complete TextSub/VobSub instruction if there's any detected srt/sub/idx/ass subtitle file
#<moviefilename>: variable of the movie filename, if you want to do all this by yourself
#Be careful, the custom script MUST return the clip object
<movie>

forward_1=MAnalyse(super, chroma=false, isb=false, blksize=32, blksizev=16, searchparam=1, search=3, badrange=(-24))
backward_2 = MRecalculate(super, chroma=false, backward_1, blksize=16, blksizev=8, searchparam=1, search=3)
forward_2 = MRecalculate(super, chroma=false, forward_1, blksize=16, blksizev=8, searchparam=1, search=3)
MBlockFps(super, backward_2, forward_2, num=50, den=1, mode=2)
SetMTMode(1)
GetMTMode(false) > 0 ? distributor() : last
return clip


Any way to fix the stuttering? I mean, I stream via LAN and my computer is not really exhausted with the calculating. I beleive it must be a problem with AviSynth or rather MEncoder.

Because MEncoder doesn't have any motion interpolation capability; ofps isn't meant for that, and neither is any MEncoder command.

I'm working on the feature and it will probably be released in the next SubJunk Build

Hopefully without AviSynth usage
