| − | == Description ==
| |
| − | [[DecombUCF]]: Decomb Using Clean Field. This function removes noise generated in one field, such as BS/terrestrial digital video scene changes and moving scenes. (Used after reverse telecine)
| |
| − |
| |
| − | If one field is dirty, Bob is used with a clean field, and if both are dirty, NR is applied.
| |
| − | Please refer to [[Clean_SC]] for frame replacement.
