Version 1.01 of Convolution3D was released on 10-19-2002 Click here to download. (36KB) Click here to view the documentation. Beta version for Avisynth 2.5 What is it? ------------ Convolution3D is an AviSynth filter that will apply a 3D convolution filter to a video stream. In practical terms, this makes it an anti-noise filter with both spatial and temporal elements. Most often, it is used to increase the compressibility of a video stream. NOTE: This filter was created by the humble/talented Vlad59. I merely host it. Vlad would like to thank bb from the Doom9 forums for the original idea and test cases. If you have questions that are not answered in the documentation, please search the Doom9 Forums before bothering Vlad. Changelog ------------- 2002/10/19 v1.01 : - Fixed a stupid bug producing garbage on last line (sometimes Copy-Paste is your enemy ;)) 2002/10/18 v1.00 : - Added version to the dll - Added named parameters - Added the special preset parameter - Added some little optimizations (~1-3% more speed) - Added a lot of comment (at least it's a lot for me ;)) 2002/09/21 Beta 4 : - Added separate pitch for each frame. Older version use the same pitch for previous, current and next frame (Thanks to dividee for this bug). - Fixed some rounding bugs with matrix 0 (Thanks to WarpEnterprises, Manono and Sh0dan for the report) - Replaced "treshold" with "threshold" : bloody typos (Thanks to CAS (a french guy) for this) - Added some parameter checking. 2002/08/24 Beta 3 : - Fixed some rounding bug - Add a little more MMX : +8% in speed but -10% in readability ;) - Again some code cleanup and some renamed variables - New parameter for fade in or fade out (see beta2 change log) : was hardcoded (value = 3) in beta 2. 2002/08/17 Beta 2 : - Fixed some bugs in the threshold check - Fixed a weird bug in the temporal blur used on borders (Should improve quality) - Added specific temporal threshold to be sure to avoid ghosting. I found this idea while reading the readme.txt of Trbarry's STMedianFilter. Thanks for the idea Tom - Completely rewrote the threshold check to allow working with bytes instead of words - Added a specific check for fade in or fade out to avoid using Temporal information in such cases (in these scenes : compressibility will be lower but quality better.) This will be optional in the next release.
