New Plugins and Utilities

Download: quad.zip

quad is a quadrilateral transformation filter similar to vcmohan's reform, although (so far) quad doesn't crash and does a true quadrilateral transformation. It uses spline16 interpolation (can be switched off for speed purposes) and is multi-threaded.

Minimum parameter requirements are 4 x,y pairs defining the corners of the target quadrilateral. The source quadrilateral can also be specified, if required.

No source, sorry - it makes use of too many half-written libraries scattered around my hard drive.

quad
====

An Avisynth plugin to perform quadrilateral transformations.

Usage
=====

quad(clip, tx0,ty0, tx1,tx1, tx2,ty2, tx3,ty3, [sx0,sy0, sx1,sy1, tx2,ty2, tx3,ty3, bool invert, bool normal, bool draft])

Parameters:
-----------

tx0,ty0-tx3,ty3: the four corners of the target quadrilateral.
sx0,sy0-sx3,sy3: the four corners of the source quadrilateral (default: clip's corners, clockwise from top left)
invert: invert the transformation (transpose t and s)
normal: specify that the coordinates are normalised to the range 0-1.
draft: don't use spline16 interpolation

The example works (with AvsPmod & VirtualDub), but there is some unreproduceable flickering of black rectangles in the top right after clip start.

Not something I've seen... is the black rectangle always the same height? Is it 1/4 or 1/8 of the clip height? Is it full width or just partial width?

Can you post a screenshot?

Good to note that a better plugin is now available. Incidentally the crashes of my "Reform" plugin was traced to an inappropriate default parameter and has been corrected. Hopefully it will not crash.

I suggest to please create a new thread wherein all comments be posted and not clutter this main annoncement thread. The comment thread may be provided a link here.

New LocateFrames script, to find frames in c clip that match frames in f clip.
Sister script to MatchFrames which is intended for matched frames extraction,
LocateFrames is intended to be usable by other scripts to identify matches.
LocateFrames given a version number of v1.06 despite being new script, as it
uses identical logic to MatchFrames.

Bug fix release for my Gimp-style Merge filters. Colour, Hue and Saturation filters fixed.
same URL as before http://sourceforge.net/projects/avisynthgmplyr/files/?
The filters are really slow as they are just c++ code.
So I tend to run the gimp filters with a 'direct stream copy' in Virtualdub for uncompressed output then run the two passes of x264 encoding using the uncompressed (merged) avi.
There is SSE2 code supplied for GIMP but I've done little x86 assembler and never GNU format assembler, so much googling and reading to do.

Update for, ShowChannels() v0.6 - 05 Dec 2012, Plugin for Avisynth 2.5+

Planar, YUY2 and RGB.

Simple plugin whose only function is to display the average Y,U and V
values for a YUV frame or R,G, and B for an RGB frame.
Also shows accumulated average for all frames visited so far.

v0.5, 31 Oct 2012, Added x,y,w,h coords, not colorspace restricted (real pain in the bum to implement).
Can use odd coords for eg YV12, and even sample a single pixel.

v0.6, 05 Dec 2012. Added Interlaced arg for Planar only. Now gets correct chroma for planar interlaced , even down to single pixel.

I take it that the intention is not to clutter this thread with inanities while it strives to benefit the community by sharing potentially useful new functionality, but I'm unsure where that distinction might be drawn. Is the thread necessarily restricted to what could be termed computer science, or does it extend to, say, handy utilities I wrote in the course of my work that others may potentially find useful?

[jmac698]

It says plugins and utilities. Are they related to avisynth or at least video?

[fvisagie]

Yes to both - http://forum.doom9.org/showthread.php?t=166588 and http://forum.doom9.org/showthread.php?t=166627, in this case.

ALBR - Adaptive lens blur repair

Function for adaptively repairing video damaged by lens blur, using a frame-adaptive repair mask, a selection of sharpeners and multi-stage motion-compensated artifact removal. It also provides blanket sharpening and denoising-only modes, the latter mainly for applying an equivalent amount of denoising to footage that did not need repairing.

SpliceFiltered

Function that simplifies the task of creating a long sequence of splices or blends between filtered and original clips by allowing the user to enter splice frame numbers and optional duration of blend (overlap) into a single text list. It's mainly intended to be used with prefiltered or prerendered clips, and/or when splice blending is needed to mask filtering transitions.

Reformer plugin is for conversion between rectangle and quadrilateral image areas. This is similar to my Reform plugin but uses matrix algebra and renders better even if the angle of rotation/displacement of coordinates are 90 degrees or more.
Reformer is probably is very much like David Horman's plugin quad. However Reformer works for YUY2 and YV12 formats in addition to RGB formats. Coordinates of both rectangle and quadrilateral can be specified.discussion on this plugin may be posted in the thread of Reformer

PlanetCrop() v1.0 new script function.

Given a series of time lapse planetoid images, locates those images in frame, crops out and joins them all together into
a video clip of required Frame Aspect Ratio, 1 FPS, with optional Auto Luma Levelling.
First scans each image establishing maximum dimensions for whole sequence (after cropping out the planets). Optionally 'grows' those
dimensions to maintain some of the area around the cropped planets. A 'canvas' size is then established to contain the now maximum
dimensions and respecting the desired Frame Aspect Ratio, synthetic black borders are added where necessary.
Borders are the areas added to maintain aspect ratio and can be hi-lited in red. Margins are areas that use the
original image content instead of synthetic black borders (where possible), they replace synthetic borders, and can be hi-lited
in green. Margins are the areas between the established crop coords and synthetic borders.

SwitchByAudio: is a new plugin which attempts to switch between two clips depending upon the length and level of audio pause.
Please see discussion here.

Hi, haven't been around for a bit, but I just noticed this thread while perusing around again. I'd like to add AviSynthLib to the list.

This library supports many things, including but not limited to:

• Reference arrays (referenceArray.avs)
• Single sized element arrays (singleElementSizeArray.avs)
• Native for loops (for.avs)
• Blocks to contain data in a string format (block.avs)
• Memory management (memory.avs)
• Profiling tool (profile.avs)
• Regression testing (testing.avs)
• File and path manipulations and searches (file.avs)
• Variable scope insertion (var.avs/varConst.avs)
• Additional hex number support (hex.avs)
• Additional string support (string.avs)
• Including script files only once with ability to have multiple auto searched include directories (include.avsi)

Follow the link for additional information.

Thanks.

Thx jmac698 - perhaps slicer can be helpful to restore some VBS data.
