Sony Vegas is non-linear video editor with many features and the best user interface, which is very customizable and easy. It has only one disadvantage - absence of good filters for picture adjustment. So I wrote some... More information about Vegas you can find on Sony Creative Software website.

Filter	Description
Auto Levels version 1.0.2	The AutoLevels filter works stretching the levels separately for Red, Green and Blue. The output color-temperature can be corrected using "Red", "Green" and "Blue" values. Also it is possible to reduce stretching among colors with Correction parameter (zero will stretch based on less corrected color and 100 for full RGB stretching).
Levels Correction version 1.0	The Levels Correction filter is based on Auto Levels filter, but it can freeze correction in time. Get source code here.
Smart Smoother version 1.22	This filter provides smooth/blur effect, but tries not to destroy picture structure. It is like Edge preserving smooth filter from Pain Shop Pro 7. This filter is based on Smart Smoother filter version 1.1 for VirtualDub and is MMX optimized, so MMX capable processor is required (K6/Athlon/Duron/Pentium/Celeron).
Dynamic Noise Reduction version 1.0.1	This filter removes noise, filtering is done across time axis. This filter is based on DNR filter for VirtualDub and is MMX optimized, so MMX capable processor is required (K6/Athlon/Duron/Pentium/Celeron).
Smart Deinterlace version 1.0.3	This filter removes interlacing in video. Use it when converting DV or other interlaced material to DivX, XViD or other video codecs, that work with progressive source only. Get source code here.
