8mm film denoising/deflickering fine-tuning

elbennodiablo · 29th October 2014, 12:19

Hello everyone, I am filtering my parents wedding video, after a so-so capture that included double frames. I had a short discussion on the filtering already at the Video Help Forum.

After removing the doubles with srestore, I end up with a 20 fps video, of which you can download some frames here: frames.rar

I stabilized the footage for comparisement reasons, but still have the nonstabilized footage. John Meyer was so kind to suggest some filtering, which I am implementing and trying to work with these frames. This is my current script:

Quote:

Loadplugin("C:\Program Files (x86)\AviSynth 2.5\plugins\Depan.dll")
LoadPlugin("C:\Program Files (x86)\AviSynth 2.5\plugins\DepanEstimate.dll")
Loadplugin("C:\Program Files (x86)\AviSynth 2.5\plugins\removegrain.dll")
LoadPlugin("C:\Program Files (x86)\AviSynth 2.5\plugins\removedirt.dll")
LoadPlugin("C:\Program Files (x86)\AviSynth 2.5\plugins\MVTools.dll")
LoadPlugin("C:\Program Files (x86)\AviSynth 2.5\plugins\MVTools2.dll")
Loadplugin("C:\Program Files (x86)\AviSynth 2.5\plugins\warpsharp.dll")
loadPlugin("C:\Program Files (x86)\AviSynth 2.5\plugins\mt_masktools-26.dll")
loadPlugin("C:\Program Files (x86)\AviSynth 2.5\plugins\mt_masktools-25.dll")
Import("C:\Program Files (x86)\AviSynth 2.5\plugins\RemoveDirtMC.avs")

### VIDEO

ImageSource("%03d.jpg", start=001, end=100, fps=20, use_DevIL=true)
converttoyv12(matrix="Rec709",interlaced=false)

### DENOISING AND DEFLICKERING
rest=last

calm = rest.temporalsoften(1,255,255,32,2).merge(rest,0.25)#.repair(rest,1).removegrain(11)
calm = calm.temporalsoften(1,255,255,16,2).merge(calm,0.25)

LOP = calm.bicubicresize(480,270).bicubicresize(1392,1048,1,0)
HIP = rest.bicubicresize(480,270).bicubicresize(1392,1048,1,0)
HIP = mt_makediff(rest,HIP)
mix = LOP.mt_adddiff(HIP,U=2,V=2)

sup1=rest.msuper(levels=1)
sup2=mix.removegrain(11).msuper()

bv2=sup2.manalyse(isb=true, delta=2,blksize=16,overlap=8,DCT=5)
bv1=sup2.manalyse(isb=true, delta=1,blksize=16,overlap=8,DCT=5)
fv1=sup2.manalyse(isb=false,delta=1,blksize=16,overlap=8,DCT=5)
fv2=sup2.manalyse(isb=false,delta=2,blksize=16,overlap=8,DCT=5)

rest.mdegrain2(sup1,bv1,fv1,bv2,fv2,thSAD=640)

### REMOVING DIRT
RemoveDirtMC(40,false)

### SHARPEN
ConverttoRGB32(matrix="rec709",interlaced=false)
LoadVirtualDubPlugin("F:\Losse Bestanden\Software\VirtualDub-1.10.4\plugins32\msu_sharpen.vdf", "MSUSmartSharpen", 1)
MSUSmartSharpen(2) # from 0 to 5 (mad)
converttoyv12(matrix="Rec709",interlaced=false)

frame 05
frame 44
frame 80

As you can see up here, I end up with ghosting in the image, because of the denoising step. How can this be solved? Or are the differences between the frames simply to big to be solved? Thank you!

feisty2 · 29th October 2014, 13:43

rest.mdegrain (xxx).repair (rest,mode=13)

feisty2 · 29th October 2014, 14:14

u can choose one or a combo of the following options
1 repair, like what I wrote above
2 more accurate motion estimation (blksize=4,overlap=2)
3 lower thSAD to filter out unwanted compensated motion blocks (replace mdegrain (thsad=640) with mdegrain (thsad=200) x 3 times)

I am not sure where you got the script you posted. It doesn't look like anything that came from the VideoFred scripts for improving film. Most of the degraining portion of the script looks like it came from the script used to recover the original frames from a "botched" transfer, which is something I assume you already did. That is the wrong code to use for the video you posted.

I ran your video through both VideoFred's script and also my heavily modified version of his script and both worked as expected and produced a good result.

elbennodiablo · 29th October 2014, 18:11

Feisty2 thanks for this addition!

Hi John, I took part of your posted script at the videohelp forum. I learnt a lot again by reading into the botched transfer topic. But I might be still combining script parts in a wrong way. Sorry for this. Good to hear that your script is working so I will give this a try! Thanks!

For my understanding, why does the deflickering in this script not work as intended, because in the original it was bobbed first?

The video you posted didn't have much flicker.

Since the script you posted is the wrong script for the job, I don't want to spend time troubleshooting it, and neither should you.

elbennodiablo · 29th October 2014, 20:15

Your modified version of Fred's film restoration script works great John!

I get this memory error though, how can I fix this?

The only things I changed in the script, was removing all SetMTMode(): modified script

Thanks again for the help. Really appreciated!

johnmeyer · 29th October 2014, 22:37

I do most of my film restoration work using VirtualDub to read the output of the AVISynth scripts, and I then encode from there. I do use MeGUI, but have never used it with any of these particular scripts. I am not familiar with the particular error message you posted.

A few things you can try.

1. Open the script in VirtualDub and see if you can get it to play without any errors. This is intended as a troubleshooting step to determine whether the problem is mostly in the script or mostly in MeGUI.

2. I used MS Word to compare your script to my original. Your changes all look OK, but one thing that might cause problems is using higher resolution. Just for grins, try changing the:

W=1392 H=1048

variables back to either NTSC or PAL SD resolution (e.g., W=720 H=480 for NTSC). This isn't meant as a solution, but as another troubleshooting step. I did a quick Google search on your MeGUI error message, and some posts indicate MeGUI issues when fed "odd" resolutions.

3. Try changing the SetMemoryMax(1000) statement to use less memory, perhaps something like SetMemoryMax(768).

Finally, while I am not a MeGUI expert, within MeGUI you can change the number of "workers" so that it doesn't consume all your cores.

StainlessS · 30th October 2014, 02:12

Hi, dont know what version MeGUI you are using but if developer build (or recent) with "Settings/Main configuration/Improved AVS Opening" ticked,
then try with it unticked, I have had problems with that and disable it (some kind of exception I think, dont remember exactly).
The given image looks to be that of the 'Video Preview' (ie set Aspect Ratio), where it seeks to middle frame, perhaps seek is involved.

In your initial script, you should not load both v2.5 and v2.6 versions of masktools (not that it matters here).

foxyshadis · 30th October 2014, 02:23

elbennodiablo, can you edit the screens into links?

StainlessS · 30th October 2014, 02:28

Foxy, Right click (In Firefox) and Copy Link Location (assuming that you want the link, OR, Save Image As).

elbennodiablo · 30th October 2014, 18:40

Hey guys, just made links out of the pictures. I adjusted the output resolution, unticked the 'improved avs opening' and changed the memory. I also replaced

Quote:

source1= Avisource(film).killaudio().assumefps(play_speed).converttoYV12()

with

Quote:

source1= Avisource(film).killaudio().assumefps(play_speed).converttoYV12().LanczosResize(720,480)

All did not prevent megui to mention the same error:

Quote:

Megui Encountered a fatal error and may not be able to proceed. Reason: Attempted to read or write protected memory. this is often an indication that other memory is corrupt

Previewing the script works and I can scan through it, but conversion is blocked. Other scripts work fine. So it might be script related(?) I am using MeGUI_2507_x86, fully updated. AvsPmod has no troubles going through the screens. Virtualdub is unable to open the script. Strange!

MeGUI has some bugs with Avisynth 2.6 (or maybe it's newer plugins?), the preview crashes all the time for me too. Oddly, VirtualDub is rock solid though. The encoding itself should go fine.

More to prevent the Hueg Liek Xbox forum-busting. This old version of VBulletin doesn't have any way to resize anything.

StainlessS · 31st October 2014, 02:20

Add a "Return Source1" immediately after "source2=Avisource(...)", does it work OK up till there (ie are the dll's loaded OK).

I was getting problems with UnsharpMask missing from warpsharp.dll (old version from 2002/2003).
Replaced with 2008 version on Wiki, works OK with original res 1392x1048 in VDMod.

EDIT: Ooops no, if AVSPmod works ok then cannot be as above. Unless you mean OTHER scripts work OK but this
one [with LoadPlugin("warpsharp.dll"),] does not.

Where does one get the 2010 version John ?
EDIT: OK John, found it in Fred's package.

Try switch off "Settings/Main configuration/Improved AVS Opening" as in post #9. (EDIT: Switches itself back on again after update I think)

Yep, was not sure if that were reason.

EDIT:
elbennodiablo,
RT_Stats has RT_Debug and RT_DebugF functions [You need DebugView (google) to view output].
You could eg put either side of the Loadplugins lines

Code:

    RT_Debug("Attempting Load Plugins")

   # Here Load Plugin() funcs

    RT_Debug("Loaded Plugins OK")

And insert additional debug lines to track how far it got before the problem bites.
NOTE, MeGUI re-opens script about 4 or five times before Preview window is shown, but VirtualDub only once.
(So in MeGUI you will see complete set of RT_Debug messages multiple times when MeGUI is working OK).

StainlessS · 31st October 2014, 03:58

elbennodiablo
I've added these lines to script (Here: http://www.mediafire.com/download/p8...idb/Frames.zip)

Code:

RT_DebugF("\n\nFILM = %s",film)
RT_DebugF("DOING PARAMETERS")
RT_DebugF("DONE PARAMETERS : Set MemoryMax")
RT_DebugF("Set MemoryMax DONE : Load Plugins")
RT_DebugF("Load Plugins DONE : Get AviSource")
RT_DebugF("Get AviSource DONE : Crop")
RT_DebugF("Crop Source DONE : Stabilizing")
RT_DebugF("Stabilize DONE : Denoise")
RT_DebugF("Denoise DONE : Sharpen")
RT_DebugF("Denoise DONE : Interpolate")  # Oops
RT_DebugF("Interpolate DONE : Result1")
RT_DebugF("Result1 DONE : Result3")
RT_DebugF("Result3 DONE : Result2")
RT_DebugF("Result2 DONE : Result4")
RT_DebugF("Result4 DONE : Source4")
RT_DebugF("Source4 DONE : Stack")
RT_DebugF("Stack DONE : Eval")
RT_DebugF("Eval DONE")

and a "return Last" after the Eval.

Should produce something like this in Debugview

Code:

00000005    0.60150105  RT_DebugF: FILM = D:\FRAMES\frames.avi
00000006    0.60159677  RT_DebugF: DOING PARAMETERS
00000007    0.60190696  RT_DebugF: DONE PARAMETERS : Set MemoryMax

00000023    0.83468759  RT_DebugF: Eval DONE

The Debug lines are output in script order and any Filter has its constructor also called in script order (non MT avisynth, no idea about MT).
If it gets all the way to the Eval line then it really would have to be problem in MeGUI I think.

EDIT: Denoise should read Sharpen, easily changed in linked script.
Also see NOTE, in last paragraph of previous post.

EDIT: OK, I've put it through MeGUI OK.
Here is result I got, 4 times opened in MeGUI (Before Preview, number probably depends upon settings eg source detector etc)

The FFMS2 line is from FFMpegSource FFMS2.avsi script, in my plugins (I added a few newlines in 'RT_DebugF("\n\nFILM = %s",film)' line
as whoever writes that FFMS2 line to Debug forgot to add a newline to the end of line [messes up formatting, and I also switched on
'Forced Carriage Returns' In Debugview]).
Also, If you use Avisynth v2.58, it outputs lots of debugging stuff to the Debugview window, to avoid the v2.58 deluge,
in Debugview, "Menu/Edit/Filter/Highlight", set Include to ':' instead of '*' as RT_Debug sends ':' with all messages and
so DebugView will exclude those message without ':' in them [Above I did not set filter and so removedirt line is there even without ':'].

I think the last group above must be some kind of seek to frame 0 (for Preview Window when Imporved AVS opening switched OFF,
seeks to middle frame when switched ON) as there is no FFMS2 line shown for that group. {Some Kind of seek to Frame 0 == Re-open script
without AutoLoading plugins again, Groucho2004 could probably explain that.}
The number of groups opened when error occurs might be an indicator of what MeGUI was doing when error occurred.

Thanks for the tips, StainlessS and foxyshadis. I am gonna try some older versions of Megui and also try an install on my 32bit laptop with XP. If that does not work, also will try the debug mode!

I just installed avisynth on my 32bit laptop and it works there, so I will be using this system for the conversions. The script does wonders, I am really fascinated by the quality of the filtered output! My parents will love this when they see it.

Tonight I will be checking the output.

Everyone here, lots of

I really appreciate this active community and all the time spent to help other people!!

The only things I changed in the script, was removing all SetMTMode(): modified script Thanks again for the help. Really appreciated! Last edited by elbennodiablo; 30th October 2014 at 18:13.

The given image looks to be that of the 'Video Preview' (ie set Aspect Ratio), where it seeks to middle frame, perhaps seek is involved. In your initial script, you should not load both v2.5 and v2.6 versions of masktools (not that it matters here). __________________ I sometimes post sober.

feisty2 I'm Siri Join Date: Oct 2012 Location: void Posts: 2,633	u can choose one or a combo of the following options 1 repair, like what I wrote above 2 more accurate motion estimation (blksize=4,overlap=2) 3 lower thSAD to filter out unwanted compensated motion blocks (replace mdegrain (thsad=640) with mdegrain (thsad=200) x 3 times)

johnmeyer Registered User Join Date: Feb 2002 Location: California Posts: 2,633	I am not sure where you got the script you posted. It doesn't look like anything that came from the VideoFred scripts for improving film. Most of the degraining portion of the script looks like it came from the script used to recover the original frames from a "botched" transfer, which is something I assume you already did. That is the wrong code to use for the video you posted. I ran your video through both VideoFred's script and also my heavily modified version of his script and both worked as expected and produced a good result.

elbennodiablo Registered User Join Date: May 2010 Posts: 10	Feisty2 thanks for this addition! Hi John, I took part of your posted script at the videohelp forum. I learnt a lot again by reading into the botched transfer topic. But I might be still combining script parts in a wrong way. Sorry for this. Good to hear that your script is working so I will give this a try! Thanks! For my understanding, why does the deflickering in this script not work as intended, because in the original it was bobbed first?

johnmeyer Registered User Join Date: Feb 2002 Location: California Posts: 2,633	I do most of my film restoration work using VirtualDub to read the output of the AVISynth scripts, and I then encode from there. I do use MeGUI, but have never used it with any of these particular scripts. I am not familiar with the particular error message you posted. A few things you can try. 1. Open the script in VirtualDub and see if you can get it to play without any errors. This is intended as a troubleshooting step to determine whether the problem is mostly in the script or mostly in MeGUI. 2. I used MS Word to compare your script to my original. Your changes all look OK, but one thing that might cause problems is using higher resolution. Just for grins, try changing the: W=1392 H=1048 variables back to either NTSC or PAL SD resolution (e.g., W=720 H=480 for NTSC). This isn't meant as a solution, but as another troubleshooting step. I did a quick Google search on your MeGUI error message, and some posts indicate MeGUI issues when fed "odd" resolutions. 3. Try changing the SetMemoryMax(1000) statement to use less memory, perhaps something like SetMemoryMax(768). Finally, while I am not a MeGUI expert, within MeGUI you can change the number of "workers" so that it doesn't consume all your cores.
