warp - geometry correction with control points (also includes new version of quad)

[redfordxx]

Two more questions, thank you...
1. debug = 4 is changing colorspace ... is there something to do about it?

2. In the script above, I have added borders to not to crop the moved image. However, quad calculates the transformation of the black borders also! Which is useless and time consuming. Can I avoid it somehow?

1. You can convert back again, that's all. It's only meant for debugging purposes so colourspace support wasn't a priority.

2. Quad has no way of knowing that you've added borders that don't need to be looked at. You could scale your input image up instead, to the desired size, and adjust your corner coordinates appropriately, but that might introduce a bit of generational loss as you'll be resampling twice.

Might be nice feature, to add borders so that quad does not go out of the picture...

Another feature request:
Choose the color of the borders....

Thanks for the great plugin.
I try to use it for warp transformations during auto-align process in the AutoOverlay plugin.
It works fine but only first few thousand frames. After that the process freezes because Warp plugin creates too many handles.
It reproduces with avisynthplus 3.5.1/3.6.1 and any sample script like this: colorbars.quad(0.1,0.1,0.8,0.2,0.9,0.8,0.2,0.9, normal=true)

Possibly something I fixed during innumerable rewrites since the last uploaded version. Please try:

Quad now works fine but Warp throws floating "Access Violation". Script:

ColorBars.warp(0,0, 0,0,    640,0, 0,0,    640,480, 0,0,    0,480, 0,0, relative = true)

[wonkey_monkey]

Strange, it works fine for me. x86 or x64?

[introspected]

The error frequency depends on how many control points specified. It reproduces very rare for me with 3 points and very often with 5 both x86/x64 and AvsPmod/x264:

ColorBars.Warp(0,0, 0,0,    640,0, 0,0,    640,480, 0,0,    0,480, 0,0,    320,240, 0,0,    relative = true)

It throws only on script loading.

Thanks for support.

It throws only on script loading.

Constructor or frame 0 GetFrame().
[probably stating the obvious]

I think I found the problem. Please download again.

Now it works perfectly.

Wonkey,
Which is the most current version of Warp, the multiple 0.1b's are now missing, the 0.1 (as in first post) cant be right,
I have 2 different version 0.2 (including one from your home site)
as from your sig, version as in AvisynthPluginInit3

return "warp/quad v0.2";

Maybe you could like include a puzzle or something, for the user to solve to figure out which version is most recent.

Come on man, get it together and give some indication of version, at least on the zip.
[then everybody could re-version the dll in some way, maybe even re-compile with a proper version resource].

I believe v0.1b (2019/09/13) is the latest version: warp0.1b.zip - archive.org

I second that, archive.org sometimes refuses to archive files if it has the same name even if the current file is newer than the old one.

[StainlessS]

Thanks RD

My ISP dont let me access achive.org, dont know why [blocked for a couple of years maybe].

It dont really matter, I was just making a current archive together with recent-ish added plugs,
I dont dare look in my big in-box to try and order about 10 years worth of plugs, and stuff.

EDIT: Incidentally, here is the real Wonkey download directory [that the wonkey web page points at]:-
http://horman.net/avisynth/download/

EDIT: Strangely, I got a version of warp from 12 Jan 2019 [from my big in-box, dll date in zip]
that also professes in source to be version 0.2 [ie supposedly more recent than the latest posted one].

I finally made the jump and tried this technique matching a Blu-ray to DVD. After watching that YouTube video the whole process just seemed intimidating, but I guess dealing with python over the last two years made it less so. The goal is to create datasets for machine learning that require very close alignment of images for super resolution upscaling. After making a few tweaks to the process for this different use case, things are looking really good. I seem to be able to get away with doing one warp for an entire video and then being choosey as to which images to use. This opens up a lot of possibilities.
