So what does this has to if I use avisource in my script? Should I still delete mpeg2dec.dll from plugins-folder or is it built-in avisynth nowadays?

Re-read my answer : change in the script all the occurence of motionmask by masktools_motionmask

@all : you should be able to use this version of MVTools : http://manao4.free.fr/MVTools-v0.9.9.1.zip

sloooowwwwww!!!!!!

oh my this baby is sloooowwwwww. Anyone else experiencing the same. I used a simple script:

Import("c:\program files\avisynth 2.5 filters\mvbob.avs")

LoadPlugin("c:\program files\avisynth 2.5 filters\dgdecode.dll")
LoadPlugin("c:\program files\avisynth 2.5 filters\LeakKernelDeint.dll")
LoadPlugin("C:\Program Files\AVISynth 2.5 Filters\undot.dll")
LoadPlugin("C:\Program Files\AVISynth 2.5 Filters\tomsmocomp.dll")
LoadPlugin("C:\Program Files\AVISynth 2.5 Filters\mvtools.dll")
LoadPlugin("C:\Program Files\AVISynth 2.5 Filters\masktools.dll")

mpeg2source("c:\france.d2v")

mvbob()

Dropped the script in VDmod and encoded 10 minute clip with 1-pass DivX 5.1.2. After 5.5 hours it was at 20% complete
I used the code in balazer's last post (looks the same as scarfis_brain) and MVTools 0.9.8.5.

@Valky,

To clarify Manao's remarks, have a look at the bottom of:

I agree it's kind of slow, but it works great .

Keep us updated on the new mvbob() .

I am currently modifying mvbob() to work with the newest mvtools and its inculded corrector.

I've got it working at 3 to 4 fps on a 640x480@29.97fps NTSC video.
My machine is an athlonXP@1.5 GHz

maybe I can optimize that script further.
maybe it will loose speed again due to new features

if your mvbob() is painfully slow, just comment out the extended motion search parameters:

Code:
mvf=bobd.mvanalyse(blksize=blksize,pel=pel,isb=false,chroma=true)#,search=3,searchparam=10)
mvb=bobd.mvanalyse(blksize=blksize,pel=pel,isb=true, chroma=true)#,search=3,searchparam=10)

OH NO WAY, dude!!! I just watched my marathon encode and WOOOWWWWW!!! Definitely blows away 100fps.com method and all others I have come across. Keep up the good work...... with maybe just a tad bit more speed Just kidding

@all: I've completed the first step.
the rewrite of mvbob() is finished.
the speed is gained. at least by factor two.

@manao: I wasn't able to get your corrector() working properly.

but please take a look yourself:

Code:

#Helper functions:

		a=stackvertical(a.crop(0,0,0,1-a.height),a.crop(0,0,0,-1))
		output = getparity(input) ? interleave(b,a) : interleave(a,b)

if I do just

mc=cv

instead of

mc=corrector(blah blah)

the output is very fine. expept of the mv-mismatches.

but when I am using corrector somehow the analysis clips are passed to the output.

I really appreciate if you could have a look into it.

That's what i thought, you interleaved analysis and output clips. Clips have to be given in that order :

analysis_0, output_0, analysis_1, analysis_2, ... analysis_n, output_1, output_2, ... output_n.

I chose that order because analysis_0 and output_0 work differently from the other. But i recon, reading again the documentation, that how clips should be given was slightly ambiguous.

wow!

now it works!

you should really update the documentation regaring this issue. it was very confusing....


hm.. but I think mvbob it still needs a lot of work.

I'll implement a function that really really makes static logos/texts/objects static.
(they are un-corrected by the corrector, but that is by nature)

I've managed to implement nearly everything I wanted to into mvbob.

download a package here:
http://home.arcor.de/scharfis_brain/mvbob/mvbob.rar

it contains all needed plugins, which are automatically loaded when importing the mvbob.avs into your personal script.
do NOT remove the plugin-dlls from the folder that contains mvbob.avs

mvbob.avs contains three functions:

mvbob(clip c, int "blksize", int "pel", int "lambda", int "th", int "ths", int "bobth", bool "predenoise")

blksize(4,8,16) -> defines the final size of the motion-blocks.
the smaller, the slower and the more accurrate the motioncompensation, but more instable, too.
so use 16 if your video is not stable enough
default = 8

pel (1,2) -> subpixel accuracy of mvtools.
default(2)

lamda(0...?)
see mvtools-documentation
default(1000)

bobth(0...255)
deinterlacing threshold for the internal motion adaptive deinterlacers (leakkernelbob/tdeint)
do not go much over 10
default(8)

th(0...255)
the threshold for correcting false compensated motion
0 -> there will be no motioncompensation in your output (everything gets 'corrected')
255-> no correction
default(8)

ths(0...255)
threshold of static area correction (bobbing prevention)
0-> no correction
255-> full 'correction' motion compensation misses will show up again
(works against th! so be careful)
default(4)

predenoise(true/false) (experimental)
is a stupid temporalsoften with fixed parameters to help the deinterlacer
show no be used, cause it fools motion estimation.
default(false)

mvfps(clip i, float fps, int "blur")

motion compensated framerate changer

fps -> target framerate

int blur-> factor of internal oversampling
blur=10 will internally sample 10 times the framerate and will blend
3 of those 10 frames together to hide motion artifacts
default(1) (no blurring)


reYV12(clip i)

reverts PAL-DV to its nature: YV12
without quality loss
speeds up things significantly in the processing chain!

report any problems and quality issues immediately, please.


EDIT:

this tool is able to do a fully motion compensated standards conversion for you!

example:

NTSC-DV to PAL:

Code:
avisource("ntsc-file.avi")
reinterpolate411() #if you wish to....
mvbob()
lanczos4resize(width,576)
converttoyv12()
mvfps(50)
converttoyuy2()
assumebff().separatefields().selectevery(4,0,3).weave()
PAL-DV to NTSC:

Code:
avisource("pal-file.avi")
reYV12() #if you wish to....
mvbob()
mvfps(59.94)
converttoyuy2()
lanczos4resize(width,480)
assumebff().separatefields().selectevery(4,0,3).weave()
hey! that's it!
easy, isn't it?

in future, if manao has hopefully reimplemented the motion interpoaltors to the newer versions of mvtools, the framerate conversion will be much faster, cause I can reuse the motion vectors of mvbob().

@ scharfis: Many thanks for sharing your latest creation.

Q: Is it possible to write a variant of reYV12() which takes RGB24-input ?

I use the Canopus-DV codec through my entire chain, and usually open the DV-avi with
Quote:
AVISource("DV.avi", pixel_type="RGB24", fourCC="CDVC")
which means I have to use ConvertToYUY2() followed by reYV12().

AVISource-opening the DV with pixel_type="YUY2" kindof squeezes the colours.

Kind regards,
Andreas

Well, I finally got this work and saw some results with it. Thanks scarfis for getting al the needed tools in a some packet.

It's awfully slow on my 1800+ machine. 1-2 frames per second.
How do you use it as just a simple deinterlacer for normal dv-pal video and is the final output always 50fps video?

the output of mvbob() is always fullrate. (50fps / 59.94fps)


use

mvbob()
selecteven()


for halved framerate output.

it won't be much faster if I would have done a special half framerate mode into mvbob(), cause all the parameters have to be calculated. No matter whether you want full or half framerate.

I can't even manage to get the speeds you're reporting!

I'm using AVS2AVI -c null to go from one uncompressed AVI file to another, and I'm getting about 0.02FPS(!!!!) converting PAL to NTSC. That's 21 hours to convert 40 seconds! This is on a P4 2.8GHz.

I'm using...

Code:
import("C:\Program Files\AviSynth 2.5\plugins\mvbob.avs")
avisource("all no grey.avi")
#reYV12() #if you wish to....
assumetff()
convertToYV12
mvbob()
mvfps(59.94)
converttoyuy2()
lanczos4resize(width,480)
assumebff().separatefields().selectevery(4,0,3).weave()
There are a couple of reasons why this code might not work or might not be optimal - I'm not sure if assumetff() is the right way to pass TFF material to mvbob()*, I know convertToYV12 without interlace-true is wrong, and the source material has already gone from YUV2 to RGB24 before it even gets into the script.**

However, all this asside(!!!), why is it _so_ slow?

Cheers,
David.

* - but I'll find out when I actually get to watch the result in 21 hours!!!

** - anyone know a way to pass raw YUV files like these (good test sequences there btw) straight into AVISynth?

UHM? 0.02fps?

this means that you are getting ONE new frame every 50 seconds ????

This cannot be the case.

I get about 0.5 to 1.5fps using this script with my AthlonXP1600+ @ 1.5 GHz (768MB DDR-266 RAM)

a plain converttoyv12 is definately WRONG!
either use converttoyv12(interlaced-true) (use this with TV-Cards captures)
or reYV12() (for PAL=DV stuff, this is the best choice!)

assumetff() and assumebff()
are used to set up the correct fieldorder.

PAL-DV is always BFF, while TV-Cards captures are more common to be TFF.

ensure that both assume?ff() calls are setting the SAME fieldorder.

is the fieldorder was set incorrectly, the output will show heavy motion jitter.

To open YUV-files directly in AVISynth, you will need the plugin rawsource.dll
get it (and other plugins, too!) here:
http://www.avisynth.org/warpenterprises/

Yes, it really is! It's been running since I last posted, and we're up to 55 frames now, ETA of about 13 hours. I've only been browsing the net. It's obvious there's something wrong, but I don't know what. It's probably a general AVIsynth problem on my system (it's just as slow in VDub), so maybe I should address it in another thread.

This isn't PAL DV, so I was going to use convertoyv12(interlaced=true). I litterally just threw this script together to see if assumetff() would work, and then was amazed at how slow it was!

Quote:

I'll check. I'd swear on previous conversions I had opposite for PAL and NTSC (not DV) to avoid judder.

EDIT: I Ctrl-C'd it. The field order seems fine - TFF on the way in, BFF on the way out with no judder (checked field-by-field in TMPGEnc deinterlace filter, even-odd). So far, the quality looks great!

Cheers,
David.
