MVBob, stuttering motion

[anton_foy]

I just tried MVBob, the best deinterlacer I ever tried.
Great work there. Although one problem is it renders a stuttering motion as if it was rendering:
frame 1, frame 3, frame 2, frame 4, frame 6, frame 5 and so on.
My footage is HDV (1440x1080 25i PAL) mpeg-2 and I dont know if this script was written for NTSC or something, ever encountered this problem?

Also I wonder if anyone have seen the MSU Deinterlacer and if it is compareable with MVBob?
Thanks

[scharfis_brain]

use assumetff() or assumebff() to set the correct fieldorder.

msu-deinterlace isn't available to the pubicity IMO.

[anton_foy]

Thank you scarfis, I tried both but assumetff() gets: frame 1, 2, 3, 10, 4, 5, 6, 13 or something like that.
Assumebff() gets like tff but 10, 11, 12, 3, 13, and so on... very strange. Also some chroma displacement occurse in the moving areas aswell as blocking artifacts (see below).

MVBob deinterlaced

(I enlarged the inerlaced/deinterlaced areas)

my script is:

DirectshowSource("C:\HD\Projekt\hdv.mpg")
ConverttoYV12()
AssumeTFF() #or BFF
MVBob()

[AI]

if clip is interlaced, need use ConverttoYV12(true)

PS You use latest mvbob?
PPS if yes, you update mvtools to v.1.0.1?

[scharfis_brain]

Do you have enough RAM installed into you computer? (1GB will be the lower limit!)
Do you use the plugin versions delivered with the package?

deactivate plugin autoloading and only load plugins that you really need!

Chroma displacement is caused by converttoyv12(). converttoyv12(interlaced=true) needs to be used in this case!

Do NOT use directshowsource! It may be responsible for the stuttering!
Use MPEG2Source instead (with DGIndex and Dgdecode.dll)
mpeg2source() will deliver YV12 by itself, so you won't need Converttoyv12.
also MPEG2source is faster, nore reliable, and consumes less memory.

[anton_foy]

Thanks guys!
Allrighty Scharfis that sounds great I will use MPEG2Source() instead.

My MVTools ver. is 0.9.9.1 Where can I get the new one?

Is this the newest MVBob, maybe im not using the right one?

hmmm. that is a pretty old mvbob with a modification I never tried myself.

try this updated one:
http://home.arcor.de/scharfis_brain/mvbob/mvbob.rar
It already includes all needed plugins. and loads them automatically.

your own script should just inculde those lines:

import("path\mvbob.avs")
loadplugin("path\dgdecode.dll")
mpeg2source("blah.d2v")
mvbob()

[AI]

I will use MPEG2Source() instead.
that I know, this filter not get frame on right order, when random access to frame. (my English is bad)

I ask about version becose latest mvbob use MVtools v1.0.0, but this version have leak memory.

I don't know about your version and about newest version (possible I test version in the middle)

[anton_foy]

Avisynth open failure:
MPEG2Source: DGindex/DGDecode mismatch. You are picking up a version of DGDecode, possibly from your plugins directory, that does not match the version of DGIndex used to make the D2V file.
Search your hard disk for all copies of DGDecode.dll and delete or rename all of them except for the one that has the same version number as the DGIndex.exe that was used to make the D2V file.

Hmmm...I only have DGDecode.dll in one place

scharfis_brain,
Thank you for your work, but:
Your must distribute only whole package of MVTools and other plugins.
(read GPL license).
At least please add info about all plugins authors and download links to your readme.

[Fizick]

To all:
Latest MVTools version is 1.0.1 today (see my site).

[AI]

(it is written by means of Russain language on white - russian humor ;) )

Use DGIndex for make *.d2v file
and read manual DGindex/DGDecode....

[scharfis_brain]

@Fizick: is it REALLY needed to put all sources & stuff into my package to ensure GPL conformity?
I am just an of enduser and putting all of this stuff into the package will blow it up unneccessary to maybe some MB which will become really uncomfortable and useless cause joe -avisynth- average (who uses that script) won't recognize the sources at all. (I haven't read the GPL yet. I'll maybe find some time next year)

For sure I agree with you to name the Authors and the places I got the packages from.

[Wilbert]

@Fizick: is it REALLY needed to put all sources & stuff into my package to ensure GPL conformity?
No, just a link to the sources is fine.

[Fizick]

scharfis_brain,
Sources probably may be omitted, but why omit plugins manuals?

[anton_foy]

hi again!
I still havent figured out how to import my .mpg -file as *.D2V -file.
Note that my file is try.mpg not try.d2v, I should convert it somehow?

Im such a newbie :P

[foxyshadis]

DGIndex (http://neuron2.net/dgmpgdec/dgmpgdec.html). :p

[anton_foy]

yeah well the thing is when I open the try.mpg -file in DGIndex it is just a black screen. Can't even play it...
When I try to save project it says: "No data. Check your PIDS"

[scharfis_brain]

Stream -> Detect PIDs
is your way to go. You need to set the PIDs (Video and Audio) manually.

[anton_foy]

OK thanks Scharfis_brain it generated a D2V file!


edit: WOW no stuttering ... plus IT IS TEN TIMES FASTER RENDERING NOW!!!
Thank you all! I will probably be back with more problems though hehe

[scharfis_brain]

do you have other mvtools.dll-files besides the one in my package on your PC?
if so, (re)move them, so that AVISynth cannot autoload them.

[mp3dom]

Scharfis, I've tried your latest mvbob (from your latest link) but I receive the error:

"There is no function named "merge"
mvbob.avs line 95
mvbob.avs line 193"

In the Avisynth "plugins" dir I have only the basics dll that came with Avisynth installation. All plugins are in another dir to avoid autoload of old filters.

I'm using Avisynth 2.55. The script is:

Import("x:\mvbob\mvbob.avs")
LoadPlugin("x:\dgindex\dgdecode.dll")
MPEG2Source("x:\movie.d2v")
mvbob()

[scharfis_brain]

install the newest AVS 2.56 alpha

[morsa]

Scharfis:
I've been playing around with this new version of mvbob.
It looks nice to my eyes.My biggest problem with it at this very moment is I'm getting quite unusable frames after every scene change.
I know for sure that I should be doing something wrong.I keep the last setting I was using with the older version:

mvbob(4,2,4000)


PS: Sometimes I'm also getting some weirds artifacts I would call "worm artifacts".they appear whenever I have a shot with a metallic fence and a horizontal travelling (pan)
thanks

[scharfis_brain]

you need to name parameters.

[morsa]

This way?

mvbob(blksize=4,pel=2)
Ok, I guess I get it it seems I've been so stupid all this time as to not see that 4000 number was a confusion with the lambda parameter of MVtools...
Sorry again...

Note: It seems that as time goes by I'm , instead of improving, becoming more and more dumb.....:(

[iceborne]

i was trying out mvbob from the lastest link above on one of my interlaced source in virtualdub and i get this error:
---------------------------
VirtualDub Error
---------------------------
Avisynth open failure:
Script error: mvanalyse does not have a named argument "truemotion"
(˜ñ, line 203)
(C:\Documents and Settings\Administrator\Desktop\hybrid progressive interlaced.avs, line 9)
---------------------------


here's my script:

LoadPlugin("C:\Program Files\DGMPGDec\dgdecode.dll")
mpeg2source("D:\tanw\test.d2v")

crop(14,4,-14,-4)

#denoise
#limitedsharpenfaster()
# Set SAR in encoder to 4 : 3
mvbob()

[foxyshadis]

You need new mvtools from the truemotion thread (http://forum.doom9.org/showthread.php?t=102071).

Has anybody converted MVBob for using with MaskTools v2.0 alpha? I'm a bit unsure regarding MotionMask<->mt_motion.
