Nnedi3

Revision as of 09:29, 25 October 2015

Description

nnedi3 is an intra-field only deinterlacer. It takes in a frame, throws away one field, and then interpolates the missing pixels using only information from the kept field. It has same rate and double rate modes, and works with YV12, YUY2,and RGB24 input.
nnedi3 is also very good for enlarging images by powers of 2, and includes a function 'nnedi3_rpow2' for that purpose.

nnedi3 is nnedi2 with improved predictor neural network architecture and local neighborhood pre-processing. nnedi3 also has multiple local neighborhood size options to better handle image enlargement vs deinterlacing and give more quality vs speed options.

Requirements

• AviSynth 2.6.0 or greater
• x64 version requires AviSynth+ r1576 or greater
• Supported color formats: RGB24, YUY2, Y8, YV12, YV16, YV24, YV411
