Using Avisynth for a Dazzle

[kiraldk]

Hi guys, i'm new to all these scripting stuff, and I wanted to have a few tips. As you probably know the Dazzle DVC 100 is a DV recorder and I use it to capture my gameplays on various games. The problem is, his quality is quite horrible :)
So I found a video where a guy made the excellent challenge of getting a great quality on the dazzle, you can check his : https://www.youtube.com/watch?v=bQurNPzKn5o
I contacted him and we exchanged some tips, but when I'm doing his way it doesn't work as well. So here's the script I made :
Avisource("test1.avi")
SetMTMode(2)
ConvertToYV12(interlaced=true)
AssumeTFF()
SelectEven()
QTGMC("Slow", EdiThreads=1)
dfttest(sigma=34)
Sharpen(0.15)
ConvertToRGB24()

Here's the result :

I just wanted to ask you if you could give me some advices to get a better quality, because I know it can be upgraded, a few plugins/filters maybe ? Or telling me what is wrong with it :)
thank you guys !

No one ?

Actually the only "big" problem I get is the darkness I have with my records..

I can't really tell how dark that is supposed to be. But you can adjust the brightness/gamma with the Levels() function, as long as there is some detail in the dark areas to begin with. If there isn't, then you'll need to make the source brighter before recording.
