AVISynth scripts not opening in Virtual Dub

[bvdd]

Hi all,

Back in November on this forum, I crash-coursed on AVISynth, and thanks to manono, Al, LigH.de, LMotlow, jagabo, and
several others who are very patient, I was up and running.

Today I'm attempting to start working on my film project again after not touching it since then - and nothing's working.

So, with my tail between my legs, I must once again ask for your help to try and get back to where I was.
To put it simply, none of my scripts will open an in VDub. The error message is 'Unable to open file: C:\AVS TEST SCRIPT.avs'.
This is the same error I get with every script I try to use. Nothing more specific than that.
All of my scripts were working fine two months ago.

Here's my setup and what I've tried today:

Windows XP Pro SP3 32bit; AVISynth 2.60; Virtual Dub 1.10.

- Reinstalled AVISynth 2.60
- Reinstalled AVISynth folder Plugins
- Reinstalled Microsoft Visual C++ Redistributable - all versions from 2010 up
- Reinstalled fftw3.dll and libfftw3f-3.dll in Windows System 32 folder

Here's my AVISynth plugins folder list:



Here's one of the the scripts I'm trying to use (AVS TEST SCRIPT.avs):

Import("C:\Program Files\Avisynth\plugins\sRestore.avs")
AVISource("TEST2.avi")
ConvertToYV12(interlaced=true)
QTGMC(Preset="faster")
Srestore(Frate=19.98)
AssumeFPS(12)
Crop(8,0,-8,0)
LanczosResize(640,480)


Thanks

Make a simple script with just:

Version()

Can VirtualDub open that?

Also, try removing the ffmpeg source plugin for VirtualDub.

Make sure you are attempting to "Open Video File", not "Run Script". The run script option is for Vdub process/batch/edit scripts, not AVISynth scripts (which should appear to Vdub as video).

Yes, I'm attempting 'Open Video File'.

Thanks.

The ffmepeg plugin is not in the VDub plugins folder.

Do you mean try a script with simply 'Version()' written?

[jagabo]

Do you mean try a script with simply 'Version()' written?

Yes. AviSynth will create a small video with the version number stamped onto it. This removes most other dependencies that might cause problems. If you can't open that script AviSynth probably isn't installed properly. Keep in mind that 64 bit VirtualDub requires 64 bit AviSynth and 64 bit filters. 32 bit Virtualdub requires 32 bit AviSynth and 32 bit filters. The two systems, 64 bit and 32 bit, can't see each others' components.

[bvdd]

Ok, it's not opening, but let's make sure I did this right:

[bvdd]

Ok, now it's opening. I wrongly assumed I needed to add the version number in the ().

So that means AVISynth is installed correctly ?

[manono]

So that means AVISynth is installed correctly ?

Yes, that's what it means. It's a standard test to make sure AviSynth itself isn't the problem.

The next step might be to try your script again, but with everything commented out but the source plugin:

#Import("C:\Program Files\Avisynth\plugins\sRestore.avs")
AVISource("TEST2.avi")
#ConvertToYV12(interlaced=true)
#QTGMC(Preset="faster")
#Srestore(Frate=19.98)
#AssumeFPS(12)
#Crop(8,0,-8,0)
#LanczosResize(640,480)

See if that opens and, if not, what the error message is.

That opened.
So now I try adding each line in one at a time, correct?

[bvdd]

Ok, so I've added every line back in (except 1 & 5 - sRestore) and it opens.
I add either of those in and it fails.

The problem is with sRestore, correct?

[Cornucopia]

Correct.

[jagabo]

Now you need to figure out why SRestore() isn't working. If you re-enable just the import line what error message do you get?

[bvdd]

The same error: Unable to open file: ..

[bvdd]

I tried replacing srestore v.2.7e with v.2.7h - no luck

[jagabo]

SRestore normally comes as a .AVSI file that autoloads when it's in AviSynth's plugins folder. Did you rename it to .AVS?

[bvdd]

Yes, here's my plugins folder once again, just in case something's amiss:

[jagabo]

Apparently QTGMC is autoloading on your system. So try renaming SRestore.AVS to SRestore.AVSI, removing the import line in your script, and see if it autoloads.

Are you using 32 bit AviSynth on a 64 bit system? Then the folder name is

C:\Program files (x86)\...

not

C:\Program Files\...

[bvdd]

That worked!

I'm using 32 bit AviSynth on a 32 bit system.

So, can I run it like this with no issues?

[bvdd]

Check that - it only opens if I have both the Import line AND the "sRestore(Frate=19.98)" line removed.

Doesn't that mean sRestore is not loading at all?

[jagabo]

Open SRestore.AVS with a text editor. Does it look OK? No obvious corruption?

[bvdd]

I'm not good enough with code to know.
Here's the file, can you tell?

[jagabo]

Looks OK to me. I compared it to v2.7g on my system and there's only a few lines different. Nothing corrupt. Replacing the older version with that version works fine.

[bvdd]

So if I have both 'srestore' lines commented out in the script, how is it loading?

#Import("C:\Program Files\Avisynth\plugins\sRestore.avs")
AVISource("TEST2.avi")
ConvertToYV12(interlaced=true)
QTGMC(Preset="faster")
#sRestore(Frate=19.98)
AssumeFPS(12)
Crop(8,0,-8,0)
LanczosResize(640,480)

[jagabo]

SRestore isn't loading or being used.

[bvdd]

I thought srestore was necessary to remove both duplicate and blended frames - Not true?

Removing those is something I definitely need to be able to do.

[manono]

How do you know it's supposed to become 19.98fps? Maybe it's time for you to provide a short 10-second sample from your source.

I thought srestore was necessary to remove both duplicate and blended frames - Not true?

It's true.

Removing those is something I definitely need to be able to do.

It does nothing with the line commented out (the '#' in front).

I think I've been tripping over myself this time, just trying to get the script to open up in VDub.

When I first started this project two months ago, jagabo suggested the frame rate was around 12fps, which looks about right to me.
But I don't know enough about scripts/code to know which line is affecting the final processed frame rate, so I may be using a script with commands that contradict each other.

All I want to accomplish is getting close to the correct speed and removing duplicate/blended frames. I'll be thrilled to get that far.

Here's another 10 sec clip from the original capture:
(I tried to convert this to mp4 but the quality was horrible)

[jagabo]

But I don't know enough about scripts/code to know which line is affecting the final processed frame rate

Import("C:\Program Files\Avisynth\plugins\sRestore.avs")

This line imports SRestore.avs as if you had included all the text of that script in your current script. This makes the SRestore function available (assuming it succeeded) for use in this script.

AVISource("TEST2.avi")

This opens your AVI file making the video and audio streams available as a stream called "last". Any time you don't explicitly name a stream it is given the name last. Anytime you don't specify a stream the stream named last is used.

ConvertToYV12(interlaced=true)

This converts last from whatever color format it is in (RGB in the case of the video you uploaded) to YV12, interlaced. So the previous two lines of this script are equivalent to:

last  = AVISource("TEST2.avi")
last = ConvertToYV12(last, interlaced=true).

From here on out I'll stop explaining the use of "last".

QTGMC(Preset="faster")

This converts each field of the interlaced source into a frame. Your source is 29.97 fps so after QTGMC last is 59.94 fps.

Srestore(Frate=19.98)

This discards frames, preferentially blended and duplicate frames, leaving 19.98 fps.

AssumeFPS(12)

This slows the 19.98 fps video down to 12 fps (equivalent to slowing a projector), increasing the running time by a factor of 19.98/12. If you left out SRestore() the incoming frame rate here would be 59.94 fps and it would be slowed to 12 fps, extending the run time by a factor of 59.94/12, about 5x.

Crop(8,0,-8,0)

This cuts away 8 columns from the left of the frame and 8 columns from the right of the frame.

LanczosResize(640,480)

This resizes the frame that's left (704x480) to 640x480.

The result of the full script attached.

[bvdd]

Fabulous explanation!

So in my case, at least so far, I can't get sRestore to load - which means I have no way to discard blended and duplicate frames, correct?

Is there another way? I'm reading about TDecimate. Should I pursue that or figure out the sRestore issue?
It worked just fine 2 months ago.

Thank you so much for staying with me.
