Are there exist any built-in or plugin way of direct samples sequence setting (in 4:4:4 and sub-sampled interleaved or planar format) from text-line (or array) defined arguments to function ?
Something like
Code:
Line(pix_fmt="YUV422P10",Y="64,64,940,940",U="512,512",V="512,512")
return clip 4*1 size (with some default fps and frame num) of the requested pix_fmt and with defined samples values ? Or may be script function ?

One way is BlankClip and Expr

eg.
Code:
BlankClip(length=300, fps=24, width=4, height=1, pixel_type="YUV444P10")
Expr("64","512","512") 
KillAudio()

You can use Expr:

Code:
Blankclip(width = 4, height = 1, pixel_type="YUV422P10").Expr("
sx 0 == 64
sx 1 == 64
sx 2 == 940
940 ? ? ?
","
sx 0 == 512
512 ?
","
sx 0 == 512
512 ?
")
The "sx" lines are acting like C "case" statements, with the final line being the last/default value.

My example was short for simplicity. I mean setting exact sequencies of samples values of longer length. For typical transient description I need to set about 8..10 Y values and 4..5 UV values. And for sustained borders I can use simple AddBorders.
For long non-fully scripting way I have a set of external simple program to wrtie UYVY set of samples and RawSource plugin. But it long way. So may be ask to add simple Debug-group function close to BlankClip but with extended color param (like array of values instead of one colour).
So currently no way to set/get samples values at given (x,y) coordinate of framebuffer ?
The hackway with StackHorizontal(BlankClip(width=2,height=1,color=2_UYVY_samples),second_blankclip_with second 2 UYVY) may not work with 10bit ? And not short form for defining string of 10 Y and 5+5 UV samples.

If even use Expr() for 4:2:2 2*1 size clips (for further hor stacking) - how to set 2 different Y values of first and second Y samples ?

Reading sample value at x,y is easier with vapoursynth editor, because it supports different pixel formats, bitdepths . You mouse over any location and it reads off x,y coordindate and corresponding Y,Cb,Cr or R,G,B value , 8,10,12,16bit, float. AVSPmod is good, but unfortunately only reads 8bit values. Even if you're not familiar with vapoursynth, you can load most avs scripts into vapoursynth and use vsedit to "see" the proper pixel values

Not sure of a good way of setting pixel values at x,y . Maybe overlay as a workaround method

"UYVY" fourcc is 8bit422, so it does not work with 10bit per channel

If you meant U, V in v210 or p210 (10bit 422 interleaved, and planar), then it will work

Untested, but maybe perform your manipulations with grayscale planes of Y, U, V and then combineplanes . StackHorizontal for 2 Y samples

Same question - how to set sequence of (exact and different) Y-only samples to 'grey' plane. And 10bit greatly wanted for HDR like PQ transfer.
Possibly without 'stacking' of 1*1 samples Y10 or Y16 clips. That is too long. No way with 'arrays' of new avisynth versions available ?
Can array be argument of user function ?
Can enviroment return number of members in array so may be loop of BlankClip(width=1,height=1,pix_fmt="Y10") and StackHorizontal possible to fill the line of samples of grey-plane from simple provided sequence of numbers ?

See my post just before yours.

Alternatively: perhaps there is an image source filter which will read Netpbm files.

"See my post just before yours."

Oh - thank you - it really works for required 10x1 4:2:2 clip like
Code:
plY=Blankclip(width = 10, height = 1, pixel_type="Y10").Expr("sx 0 == 509 sx 1 == 509 sx 2 == 509 sx 3 == 509 sx 4 == 509 sx 5 = 498 sx 6 = 446 sx 7 == 361 sx 8 == 292 276 ? ? ? ? ? ? ? ? ?")
plU=Blankclip(width = 5, height = 1, pixel_type="Y10").Expr("sx 0 == 270 sx 1 == 263 sx 2 == 330 sx 3 == 761 754 ? ? ? ?")
plV=Blankclip(width = 5, height = 1, pixel_type="Y10").Expr("sx 0 == 203 sx 1 == 224 sx 2 == 271 sx 3 == 832 821 ? ? ? ?")
CombinePlanes(plY, plU, plV, "YUV", "YYY", pixel_type="YUV422P10")
And another question - are there ways to define >8bit YUV colour for AddBorders() ? Or only create separate 2x1 clip with same way and point-resize to required size and StackHorizontal ?

How do you merge files together in AVIsynth? And with programs like AVSPMod or MeGUI?

a=YourPreferedSourcePlugin("D:\yourvideo1.mkv")
b=YourPreferedSourcePlugin("D:\yourvideo2.mkv")
a++b

Btw, this is wrong thread to ask questions about Avisynth:

@VoodooFX is right, you use append, so you set your file to a variable, your other file to another variable and then you append them together with ++.
Now, here's the catch: they must be exactly the same, namely they must be with the same resolution, framerate, color sampling, bit depth and if they have audio, that should be the same too, like, you cannot append a clip with audio to another which doesn't have it.
Of course, as a user and encoder writing a script, it's your duty to make sure those match, hence performing conversions.

How do you update AVISynth and/or AVISynth +? How to you know when you need to update it?

Just FYI, I raised an issue here https://github.com/AviSynth/AviSynthPlus/issues/302 'cause apparently WAVSource() cannot index files larger than 4 GB and that affected my supply chain...

I have trouble on my Windows 11 machine with the default plugin folders of Avisynth+. It seems they don't get recognized and the plugins stored in
"C:\Program Files (x86)\AviSynth+\plugins64+" f.e. do not get auto-loaded. How can I fix that? Re-install of Avisynth+ did not help.
Right now I have to import all my filters manually from that folder which is a little annoying.

Strange, my Windows is win 11 too and didn't got that problem

Mine didn't get that problem either. They were loaded automatically just fine, as they should.
Could it be some permission issues about the Program Files folder? Or perhaps Windows Defender blocking it? Dunno. It works on my end, I cannot reproduce it.
