I can't upload my plugins folder - the 169 files in there include about 10 you need (not sure which without checking!) and it would be against the licence of most of them to share them in this way. That's why there isn't a neat package to do this already (AFAIK).

http://avisynth.org/mediawiki/MC_Spuds
...though I've attached the old version I'm (intentionally) using - rename it to .avsi (why doesn't the forum allow .avsi?! but does allow avs) and pop it in the plugins folder.

other files in the above link, or (directs links) here:

In AVIsynth, DirectShowSource is usually the last resort (with some formats it's not frame accurate, audio sync breaks, and you can't access all pixels formats). Should be OK for DV, but Cedocida via AVIsource is better.

Hope this helps.

Cheers,
David.

I have downloaded the codec as advised ..... thanks for your help .. I'll go get the rest.

You attached mc_spuds original ... should I use that or get the current version ?

[2Bdecided]

It's up to you. I liked that one better (I have two other versions saved), but YMMV!

Cheers,

starting to build the plugins folder ... most of these have been groups of .dll files. with a couple of .avs or avsi files.

If a plugin has a group of 'dll' files can I drop the complete folder of them into plugins folder or do I need to copy across just the 'dll' files.



On some when I unzip the pack i.e. masktools-v2.0a36 it creates some dll files and also sub folders with H files, is it correct to drop the complete contents i.e dll's and the folders in the Plugin folder in AviSynth ?

Or again can I drop the complete unzipped folder with all it's content & subfolders into the plugins folder ?

[Tafflad]

In case my text is unclear .. I have got hold of each filter pack .. once unzipped most craete a folder with a number of dll files .. some have multiple sub folders.
Am I OK to just drop the unzipped folder into the Plugin folder .... which shows for example currently the pic attached:

The dlls need to be in the plugins folder.

Any avs files that contain functions need to be renamed to avsi (to autoload) and put in the plugins folder.

.h, .c etc are all source code - you don't need these. Won't do any harm if you copy them over.

IIRC things in subfolders in the plugins folder _won't_ autoload - so make sure all dlls, avsi are right there in plugins. (I could be wrong about this - can't hurt!)

Hope this helps.

Cheers,
David.

got the script to run ... took a lot of Googling around for the filters.
I drop it on VD and it runs .... interesting that both left & right screens in VD are the same ? ... i.e both show view after VHS script run, is this correct ?

Yes. VirtualDub receives the processed video from AviSynth -- it has no idea what the video looked like before AviSynth filtered it. VirtualDub's two windows will look identical unless you add VirtualDub filters.

Note that masktools has two different dlls for different versions of Avisynth.
For the standard installation, you should copy only mt_masktools-25.dll to the plugins folder.

Thnx I'll check which dll I have installed

Do I need to have both MaskTools-v1.5.8 and v2.0a.36 or will just the latter do ?

[Gavino]

For mc_spuds, only v2.0a.36 is required.
There are some script functions that need v1.5.8, but I don't think your script does. However, these two masktools versions can co-exist because they use different function names, so it won't hurt to install both.

I also have mt_masktools-26.dll
Is this what you mean by two different dlls .... should I therefore remove that one ?

Yes, mt_masktools-26.dll should only be used with the still experimental Avisynth v2.6.
For the Avisynth v2.5x series (the latest is v2.58), use mt_masktools-25.dll.

I don't know your deck. Try turning off the AI function.

By the way, your DV AVI had illegal values in the chroma channels. That's one reason why the reds are blown out. And why I used "cont_v=-40" in ColorYUV().

Hi Jagabo ... how do you identify the levels are wrong (not disputing they are) ... do you run any analysis tools to look at values .. (I have seen some mention of analysis scopes within AviSynth)

The end result here as been a big improvement ... I need some help on understanding things for use on other tapes.

In your tweaked version ... what would be the base settings that you would start with on an SVHS tape?

Then what steps/sequence you go through to find out what values to set in.


Be good to know the sequence you follow.

All of my tapes are PAL, most are SVHS.

Yes, I used VideoScope() in AviSynth:

http://avisynth.org.ru/docs/english/externalfilters/vscope.htm

Looking at the Y, U, and V channels separately I was able to see that the V channel exceeded 240 on the bright reds. You would need to look at some more footage with more colors to figure out exactly what the adjustments should be.

I have obtained the dll for this .. any hints about how to use it .... the page by the author has not helped a great deal.

[2Bdecided]

There's the rather simple (and built-in)

histogram(mode="levels")

Which will add bar graphs down the right hand side.

See here...
http://avisynth.org/oldwiki/index.php?page=Histogram
...under "levels mode"

The highlighted regions at the left and right of each graph represent illegal values.

David.

I'll go play

Like most things with AVISynth and VD ... seems there are loads of possibilities, but not easy to find out how to use them.
