Is it possible to Fix Bad Reception Artefacts with AviSynth??
I have a 720 x 480 interlaced video sample HERE (10MB in size)
There are wavey line artefacts caused by a bad TV reception. Is it possible to remove those artefacts with AviSynth? If so, could you please suggest a script. Thanks Last edited by VideoFanatic; 15th November 2011 at 18:48. |

a combo of fft3d + neat should help i believe
Good news is these interferences are on the Y component only (checked with neat's component viewer), bad news is there is a lot , in the Mid frequencies at that (6,9.6,9,1) for high,mid, low freqs respectively Otherwise there is the multiple capture technique which "may" help the script # need to capture the video 2 or more times vid1 = AVISource("C:\my1stcapture.avi", fourCC="HFYU", pixel_type="YUY2")("file1.ext") vid2 = AVISource("C:\my2ndcapture.avi", fourCC="HFYU", pixel_type="YUY2")("file2.ext") Merge (vid1, vid2) Probably a combination of all these for perfect result will be best: 1st medium denoising each capture then merge them Last edited by Mounir; 15th November 2011 at 19:01. |

Defreq is the only plugin I know of that attempts to deal with the wavy lines. However, since the lines are coming and going in your clip, and their angle and spacing changes a lot, I doubt very much that you are going to be able to get much help even from that plugin because it assumes a constant angle and distance for the interference lines.
