Problems with SharpResize

[Chainmax]

I'm currently making a high resolution rip from my"Lion King" DVD. Here's the avs I'm using:

LoadPlugin("C:\MPEG-4\Herramientas\Avisynth filters\aWarpSharp.dll")
LoadPlugin("C:\MPEG-4\Herramientas\Avisynth filters\WarpSharp.dll")
Import("C:\MPEG-4\Herramientas\Avisynth filters\SharpTools-v0.3.avs")
mpeg2source("C:\MPEG-4\LionKing\ReyLeon.d2v")
Telecide(order=0,guide=1,post=1,hints=true)
KernelDeint(order=0,sharp=true)
Decimate(cycle=5,mode=2,quality=3)
Undot()
Sharpresize(1008,608)

I tried this with the warpsharp DLL in mf's homepage and the new version (supposedly more stable) that was posted here a while ago. I also tried autoloading everything (using the new warpsharp DLL) but avisynth (v2.54) keeps reporting an access violation error every time. What's going on?

[K-Dash]

try this res (1024x608) instead.

[Chainmax]

Would that make a difference? 1008 is also a MOD16 width, plus 1008/608 is nearer to 1.66 (the source's aspect ratio) than 1024/608 is.

[mf]

I presume your source is MOD4 and YV12. Other than that, I see no problems. How are other versions of AVISynth?

[Chainmax]

Well, it is a commercial DVD, so I assume as well that it is YV12 and MOD4. I'll try the latest avisynth CVS release and report back.

[Chainmax]

No luck. The latest avisynth CVS also reports an access violation error. I even removed my v2.0x plugins folder and the oldplugins avsi (it does require to unzip msvcr70.zip in the system folder, right?). I'm going to try an older stable version.

[Wilbert]

If you are using the latest warpsharp package, you need msvcr71.zip. See AviSynth faq.

[Chainmax]

As I already said, I used both the latest warpsharp DLL linked somewhere in here and the one that mf has in his website. I'll try installing msvcr71.zip.

[Chainmax]

Ok, I copied both files in 71.cab to the windows system folder. Using Avisynth v2.55, I get the following error message:

Avisynth open failure:
Evaluate: Unrecognized exception!
(SSTov, line 37)
(C:\MPEG4\LionKing\LionKing.avs, line 6)

The script being now:

mpeg2source("C:\MPEG-4\LionKing\ReyLeon.d2v")
Telecide(order=0,guide=1,post=1,hints=true)
KernelDeint(order=0,sharp=true)
Decimate(cycle=5,mode=2,quality=3)
Undot()
Sharpresize(1008,608)

It seems to be a problem with sharptools now :confused:.

[mf]

and 2.5.1, 2.5.3 (and 2.5.4)? I have not yet upgraded to 2.5.4 and ever since 2.5.1 CVS I've had no problems with SharpTools. If you continue to experience problems, this should work too:

sinput = last
stywidth = 1008
styheight = 608
stcwidth = stywidth/2
stcheight = styheight/2
sinput.GreyScale()
sy = last
sinput.UToY()
su = last
sinput.VToY()
sv = last
sy.LanczosResize(stywidth*4, styheight*4)
XSharpen(255, 255)
LanczosResize(stywidth, styheight)
sy2 = last
su.LanczosResize(stcwidth*4, stcheight*4)
XSharpen(255, 255)
LanczosResize(stcwidth, stcheight)
su2 = last
sv.LanczosResize(stcwidth*4, stcheight*4)
XSharpen(255, 255)
LanczosResize(stcwidth, stcheight)
sv2 = last
YToUV(sy2, su2, sv2)

[Chainmax]

So, the new script would be

mpeg2source("C:\MPEG-4\LionKing\ReyLeon.d2v")
Telecide(order=0,guide=1,post=1,hints=true)
KernelDeint(order=0,sharp=true)
Decimate(cycle=5,mode=2,quality=3)
Undot()
sinput = last
stywidth = 1008
styheight = 608
stcwidth = stywidth/2
stcheight = styheight/2
sinput.GreyScale()
sy = last
sinput.UToY()
su = last
sinput.VToY()
sv = last
sy.LanczosResize(stywidth*4, styheight*4)
XSharpen(255, 255)
LanczosResize(stywidth, styheight)
sy2 = last
su.LanczosResize(stcwidth*4, stcheight*4)
XSharpen(255, 255)
LanczosResize(stcwidth, stcheight)
su2 = last
sv.LanczosResize(stcwidth*4, stcheight*4)
XSharpen(255, 255)
LanczosResize(stcwidth, stcheight)
sv2 = last
YToUV(sy2, su2, sv2)

right? I'll try it and report back.

[Chainmax]

I keep getting an avisynth error message, only without the "(SSTOV, line 37)" line and this time the error is at line 21 of the script. So, there's something wrong with:

su.LanczosResize(stcwidth*4, stcheight*4)

[scharfis_brain]

try to set a higher memoryvalue for avisynth

setmemorymax(160)

at the top of your script.

you can also choose a higher value (in Megabytes) depending on your system's RAM.

[Chainmax]

I'll try setmemorymax(128) since unfortunately 128Mbytes is all I have right now (I lost the other 128Mbytes I had, long story :()

[Chainmax]

No luck, I get the same error message. Would replacing the following lines:

sy.LanczosResize(stywidth*4, styheight*4)
su.LanczosResize(stcwidth*4, stcheight*4)
sv.LanczosResize(stcwidth*4, stcheight*4)


with the following ones:

sy.LanczosResize(stywidth*3, styheight*3)
su.LanczosResize(stcwidth*3, stcheight*3)
sv.LanczosResize(stcwidth*3, stcheight*3)

be of any help? If I'm not mistaken, what this would do is use a 3x image for supersampling instead of a 4x one, thus reducing memory requirements. Am I right?

[mf]

Yes, it would kill detail and edge smoothness too, but yes.

[Chainmax]

Ok, then. I guess I'll just have to wait until I receive the missing memory :(.
