MVTools crash

[bully`]

Hello everyone!

I was wonder if anyone could perhaps help me out by finding a solution to an issue I’m facing with MVTools.
Firstly, my level of understanding of avisynth is basically a little bit more than that of a beginner, so please bear with me!
I’m trying to create motion blur for my gaming footage by using MVTools- and I am quite satisfied with the result, but it unfortunately still shows some artifacts. What seems to work in getting rid of most of these artifacts is upping the value of blksize. However, when I attempt to change the blksize to 32 or higher (a value of 16 or below works fine), virtualdub (or WMP) crashes.
Here’s what it shows:
https://www.dropbox.com/s/xh8h4fp5120jqft/crash-mvtools.jpg?dl=0

This is the script I’m using:

SetMTMode(2)
LoadPlugin("C:\Program Files (x86)\AviSynth\plugins\mvtools2.dll")
ImageSource("D:\Movie Making\Return to Castle Wolfenstein - Movie Edition - Old DemoViewer\demoViewer\screenshots\shot%.4d.tga",0,4833,500)
ConvertToYV12()
super = MSuper(pel=2)
backward_vectors = MAnalyse(super, isb = true, blksize=32, truemotion=true)
forward_vectors = MAnalyse(super, isb = false, blksize=32, truemotion=true)
MFlowBlur(super, backward_vectors, forward_vectors, blur=100)
MFlowFPS(super, backward_vectors, forward_vectors, num=500, den=5)

I’ve installed several versions of avisynth and virtualdub, including 64 bit versions- and tried different Setmemorymax() values. I’ve also noticed that if I set the value even higher, like 48, it crashes instantly whilst 32 still allows me to scan trough a few frames before it crashes.
I hope someone might have the solution!

With friendly regards.

What resolution does the .tga file have? Have you tried without "SetMTMode()"?

[pinterf]

SeMTMode is not relevant here if Prefetch is not specified.

Could not reproduce, avs+ r2544, mvtools2 2.7.23 here. x86 or x64.
Script is working from avsmeter and vdubmod, set BlkSize to 48.
The difference is that my source is not ImageSource. Tried on a source with fullhd and 4k, no freeze here, even with prefetch(10)

What are the dimensions of your video? And which versions are using (use AvsMeter/AvsMeter64 to tell it)?

[bully`]

Hello!

The resolution is 1920 x 1080, and unfortunately without SetMTMode it still does the same.

[pinterf]

Now tried with tga images, it works for me.
Full HD with Prefetch(10) required approx. 1600 MBytes of memory, single thread mode only 285MB.
So it's probably not a memory issue. Check dll versions.

Thanks for the reply so far everyone.

I will look into the avsmeter, I've not used it before so I need to read some documentation.

I hope I did it right; right clicked and opened the script with AVSMeter. It then proceeds to scan and closes when it reaches frame 100.

What it shows before it closes:

Sorry, whatever I seem to try, it doesn't generate a log file.
I ran cmd.exe and did the following:

It definitely does its thing but it doesn't seem to produce a log.
Perhaps a screenshot will be useful for you as well:

What are the dimensions of your video? And which versions are using (use AvsMeter/AvsMeter64 to tell it)?

I'll try to install the same setup as yours and see if that helps, thank you!

[pinterf]

Anyway I'll check it with classic avisynth, there is no crash without reason.

[Errors]
Exception 0xC0000005 [STATUS_ACCESS_VIOLATION]

For this x64 setup, does it crash at the same frame when you run it multiple times?

[Groucho2004]

Sorry, whatever I seem to try, it doesn't generate a log file.
I ran cmd.exe and did the following:

C:\AVSMeter\avsmeter.exe -avsinfo -log

It definitely does its thing but it doesn't seem to produce a log.
Perhaps a screenshot will be useful for you as well:

https://www.dropbox.com/s/ff186af7ofu81yz/avsscan2.jpg?dl=0
The log file is created in the current directory which in your case is "c:\windows\system32".
Anyway, I can't see anything wrong judging from the screen shot.

For this x64 setup, does it crash at the same frame when you run it multiple times?

Yes it does, it keeps crashing at 112.
Also, as of yet blksize=16 still works fine, even with this new setup.

[pinterf]

Great. Now I'd like to ask you to prepare those tga's for me. Before the crashing frame and some from after it as well. If they are too large try to figure out tge minimum frames and starting point where the crash is still reproducible. Then I can debug it if it's crashing for me as well. Thanks

[bully`]

You'd like me to to upload the tga's for you?
AVSMeter also states that the number of frames is 967, but that is probably my scripts doing (dividing by 5). The original source is 500 fps and has 4833 tga's.
So I'm guessing we'll want to have tga's from... let's say frame 520-559 and 561 to 601 (560 = 112x5) then?

[bully`]

Anyway, here they are:

Thanks a lot for the help!

[StainlessS]

Just out of interest, what happens if you start image list part way through eg @ 50 or 100,

ImageSource("D:\Movie Making\Return to Castle Wolfenstein - Movie Edition - Old DemoViewer\demoViewer\screenshots\shot%.4d.tga",100,4833,500)

[bully`]

Then it crashes after 101 and 91 frames. :D
I tried several starting points, but it all crashes sooner or later.

[StainlessS]

Have a look at frames around 112*5 [EDIT: @560], any corruption apparent ?

EDIT: 112 - (100/5) == 92, quite near to 91

EDIT: Maybe try start at 450 [450/5=90]. Maybe fault within first few frames.

EDIT: Oops, I mean start at 550 [550/5=110]. (or 540 if that succeeds)

[pinterf]

No luck with this short sequence, you can delete it :( Could you upload the images from the beginning? I'm getting really curious.

Yeah, I noticed that too. but even if I put the starting point beyond that "critical" area it still does the same.

@pinterf And I am compiling a .zip, but it'll be big; like 3.5 gb. It'll take a while to upload, and I'm actually not sure if dropbox can handle it. I'm happy you're curious about fixing the issue though haha :thanks:

[pinterf]

No rush, I'll look at it nine hours later, we all love solving puzzles don't we. (Or we love having no puzzles at all? Choose one. :)

I think our love for solving puzzles and problems makes us such efficient predators ...and avisynth coders.

May you feast your eyes upon my tga's.

[pinterf]

Big thanks. Successfully crashed at frame #100, for me it happened only with 32 bit Classic avisynth 2.6.0.5.
Now that's something. But be patient it would take time for me to debug. Until then find a 386dx40 to play the original wold3d on.

[bully`]

That's great to hear! And of course just take all the time you need, I'll be busy killing this guy:

Something that may be of interest for you as well; I let the game record compressed .png's instead of tga's, which resulted in an output size of about 2.40 - 2.60mb per screenshot.
However, it still does the same; blksize=16 works, 32 doesn't.

greets!

[pinterf]

Fixed but still testing. Depending on the motion vectors (source clip dependent) MFlowBlur would overaddress the reference clip, accessing memory area beyond the real source frame.
nPel=2, nPel=4 was surely affected.

[bully`]

Ah I see, so I take it it's an issue within mvtools and not something I can fix by adjusting my script?
Anyway great news that you've discovered the problem!

Thanks for the report. Fix is released. At least it works for me now.

Tested. Working fine now!
Thank you for the effort, and I'm glad my issue helped to iron out a bug :).
