Advice on how to Improve/restore video quality with avisynth
Hi everyone!
I'm trying to improve the video quality on a old music video clip, convert it to dvd resolution and hopefully be able to improve it. A few years ago (2006) i asked for some help on a similar situation: http://forum.doom9.org/showthread.php?t=112993 i followed some advices of that thread but im unable to improve the video, i tried the demo version of neat video + virtualdub but didnt help either, tried the noise filters in avidemux but i didnt see any difference. Can someone help me/give advice on how to do it with avisynth? Perhaps the quality cant be improved? here's the link to the video (10mb). http://www.mediafire.com/?1cshqp3uh7xgps1 Thanks Last edited by ricardo.santos; 1st October 2012 at 23:54. |

@ricardo.santos
assuming Pal 1/2 dvd 352x576 I would open with ffvideosource resize to (352,576) with your favourite resizer use assumefps=25 use dfttest() - the default settings are slow - but it is better than fft3dfilter then encode with HCenc or Quenc using dvd-compliant settings e.g. ffvideoSource("C:\video.mp4") - you'll need ffmpegsource -> http://code.google.com/p/ffmpegsource/ assumefps(25) bilinearresize(352,576) dfttest() you will need libfftw3f-3.dll in system32 folder for dfttest ftp://ftp.fftw.org/pub/fftw/fftw-3.3.2-dll32.zip |

Requires libfftw3f-3.dll to be in the search path eg system32 (or syswow64 on 64bit, I think).
dfttest.dll in Avisynth plugins dir. EDIT: Quote:

Hi everyone!
Thanks for all the info/help, just in case anyone finds this thread in the future, the dfttest.dll isnt in the zip links provided in the previous comments, thats why it wasnt working the correct link for the 2 files (libfftw3f-3.dll and dfttest.dll) is: http://web.missouri.edu/~kes25c/dfttestv18.zip Thanks everyone! |
