Free neat video demo software for windows

Neat Video is a filter plug-in designed to reduce visible noise and grain in digital video sequences produced by digital video cameras, camcorders, TV-tuners, analog video or digitizers of film.
Main features:
- Both intra-frame and temporal filtration
- Advanced Noise Reduction to reduce noise and grain in video sequences
- Smart Sharpening to make video look sharper without amplification of noise
- Automatic noise analyzer to adapt the plug-in to any video sources
Note: Neat Video plug-in for VirtualDub is currently produced in three editions: Demo, Home and Pro. Demo plug-in is a freeware edition of the software with limited functionality. Home plug-in is intended for home users and supports up to DVD-size video data. Pro plug-in provides professionals with all Neat Video features without limitations.
System requirements:
- VirtualDub
- Pentium-II class machine or better
- 128 MB RAM or higher
- True color display, resolution 800x600 or more

Enhancements:
- Improved profiling:
- Auto Profile now selects better areas for noise analysis producing higher-quality profiles leading to better filtration
- Neat Video can now build noise profile using smaller frame areas; this is useful when the video clip has small frame size and contains only small featureless areas suitable for profiling
- Explicit selection of video scan type - progressive or interlaced - to select the best processing method depending on type of footage and workflow
- Increased speed of temporal and intra-frame filtration
- Improved memory utilization in the plug-in
- Improvements in the internal image viewer
- A minor bug in the progress bar made GUI freeze in some rare cases, fixed
- Preview in certain frame areas with specific filter settings caused a crash, fixed

Major Features:

1. 8x8 and 4x4 adaptive spatial transform
2. Adaptive B-frame placement
3. B-frames as references / arbitrary frame order
4. CAVLC/CABAC entropy coding
5. Custom quantization matrices
6. Intra: all macroblock types (16x16, 8x8, 4x4, and PCM with all predictions)
7. Inter P: all partitions (from 16x16 down to 4x4)
8. Inter B: partitions from 16x16 down to 8x8 (including skip/direct)
9. Interlacing (MBAFF)
10. Multiple reference frames
11. Ratecontrol: constant quantizer, constant quality, single or multipass ABR, optional VBV
12. Scenecut detection
13. Spatial and temporal direct mode in B-frames, adaptive mode selection
14. Parallel encoding on multiple CPUs
15. Predictive lossless mode
16. Psy optimizations for detail retention (adaptive quantization, psy-RD, psy-trellis)
17. Zones for arbitrarily adjusting bitrate distribution

Enhancements:

• Change all dct arrays to 1d.
• The C standard doesn't allow you to iterate 1-dimensionally over 2d arrays, and nothing other than the dsp functions themselves cares about the 2dness of dct.
• This fixes a miscompilation in x264_mb_optimize_chroma_dc.
