So I have this video of an experiment of mine running looped several times, and I want to average it out to reduce noise. Does anyone know of a filter that would do this? |

If you mean that you have several times the same images and you want to 'merge' them to obtain more quality images, I should not know how to do that.
Sorry.
But if you simply want to apply a 'denoise'-filter, then you could try the "MSU Denoiser Filter" that you can download at:
http://www.compression.ru/video/denoising/...g/index_en.html
and with a little Googling you will certainly find other denoising-filters too ...

For two videos you can use AviSynth with "Layer" or "Overlay" filters:
| CODE |
clip1 = AviSource("yourvideofilename.avi").Trim(0,127).ConvertToYUY2
clip2 = AviSource("yourvideofilename.avi").Trim(128,255).ConvertToYUY2
return Layer(clip1, clip2, "fast")
|
or
| CODE |
clip1 = DirectShowSource("yourvideofilename.nonavi").Trim(0,127)
clip2 = DirectShowSource("yourvideofilename.nonavi").Trim(128,255)
Overlay(clip1, clip2, mode="blend", opacity=0.5)
|
Download and install AviSynth, read manual, make script(s)
Use "AviSource" for AVIs, "DirectShowSource" for other containers.
Insert actual name of your video.
Tune Trim to select desired part of video (my example is for 256 frame length video)
With "Import" filter you can build script for more (4,8, etc.) videos |
