The power of Avisynth: new 8mm film restoring examples

Hello everybody,

New film 8mm restoration examples on Vimeo and youtube:

https://vimeo.com/user678523/videos/all/sort:date

https://www.youtube.com/channel/UC_k...CujwT_fZHN6jlg

Please set Vimeo and Youtube player quality to HD if possible.

Used filter chain:

- RemoveDirtSMC()
- GamMac() (wonderful filter, thank you again Stainlesss)
- DePanStabilize()
- Tweak() (6x tweak() separate colors with starthue and endhue)
- RgbAdjust()
- McDegrainSharp()

- Special sharpening:
- UnsharpMask (from WarpSharp) radius 3
- blur
- Unsharpmask radius 2
- blur
- final: Sharpen()

It seems that adding blur between sharpening steps avoids halos.
I buy a Belgian Beer for someone who can show me halos on my example clips


I had to solve a few problems: the newest DePan.dll 1.13.1.0 is very good, no more issues at scene change. But it creates some kind of "raster" effect in the AvsPmod preview. In VDub however, this effect is not there.

After many testings, I discovered that MvTools2 2.5.11.22 (used both in McDegrainSharp and RemoveDirtSMC) was causing the problem. I replaced it with MvTools 2.4.2.0 and the "raster" effect in AvsPmod was gone.

Also, RemoveDirtSMC() was causing problems in AvsPmod when trimming. (frame read errors) This was solved by changing blksize to 16 in MAnalyse.

Anyhow, I'm pretty happy with the results.
Feedback and/or suggestions are welcome as usual

PS: the Vimeo clips can be downloaded in Xvid for further examination


Fred.
