-I did several tests with the QTGMC and MCTemporalDenoise
and in cases of high motion shots QTGMC seemed to me more efficient myth with high presets (A more natural result, without seeming plastified) than MCTemporalDenoise
-I do not know if awarpsharp is making any difference here, honestly I do not know
I would like opinions, criticism, if I am going the right way
The result sounds good to me but I really do not have the clinical eye to know if this could be better, or if the parameters are overly incorrect for this,
If you were to do it, how would you do it?
Code:SetMTMode(3) DirectShowSource("C:\Documents and Settings\USER\Desktop\1998 250 Supercross Review.mp4") SetMTMode(2) vinverse() QTGMC(preset="Slower") BilinearResize(width/2, height) aWarpSharp(depth=5) Spline36Resize(width*2, height) Sharpen(0.9, 0.0) AssumeTFF().SeparateFields().SelectEvery(4,0,3).Weave()

Here a result:
What are you trying to accomplish?
jagabo was asking what in the original video you think needs to be corrected or improved?
You're the guy who did it:
[Attachment 46571 - Click to enlarge]
I think the original video contained interlaced artifacts, blurry image, and a grit that only gets very apparent on a big tv.
I'd really like to know exactly what's wrong with the original video, and know what really can be fixed, but I do not know where to shoot.
I think the final result seems too blurred, but I can not make more sharp without ruining everything.
I think I'm learning from all you.

That video was originally interlaced and it was improperly resized vertically causing the two fields to partially commingle. There no real way of fixing that, about all you can do is more fully blend them together. And when a video looks this bad it's debatable what constitutes and improvement. Maybe something like:
LSmashVideoSource("Before-1998-SX.mp4") Blur(0.0, 1.0).Sharpen(0.0, 0.7) # remove residual comb artifacts then restore sharp horizontal edges Spline36Resize(320, height) # about the real resolution of the video QTGMC(InputType=1) # edge cleaning MergeChroma(aWarpSharp(depth=5), aWarpSharp(depth=30)) # more edge cleaning and sharpening, much more for chroma Sharpen(0.5, 0.0) # sharpen vertical edges nnedi3_rpow2(4, cshift="spline36resize", fwidth=720, fheight=540) # back to the original frame size, sharp without adding aliasing
That script concentrated on blurring the residual comb artifacts and sharpening. What else are you looking for? You mentioned MCTD in your first post. As you noticed, strong enough noise reduction to make a difference is going to remove any detail that's left in the video. But since you're already using QTGMC, try using it's built in denoiser.
QTGMC(InputType=1, EZDenoise=2.0, DenoiseMC=true)
DirectShowSource("C:\Documents and Settings\USER\Desktop\Before-1998-SX.mp4") Blur(0.0, 1.0).Sharpen(0.0, 0.7) # remove residual comb artifacts then restore sharp horizontal edges Spline36Resize(320, height) QTGMC(InputType=1, EZDenoise=2.0, DenoiseMC=true) MergeChroma(aWarpSharp(depth=5), aWarpSharp(depth=30)) Sharpen(0.5, 0.0) nnedi3_rpow2(4, cshift="spline36resize", fwidth=720, fheight=540)
This, really is very close to what it should be.!
I can see (obviously) some annoying artifacts in the high motion shot, would this be a good idea? vinverse()
Ps: after play/replay............mentioned "artifacts" is in fact a residual noise...

Try it and see. I recommend you try the changes individually as well as together and see how each effects the video. The difference between 2.0 and 2.5 in EZDenoise will be subtle.
I suggest you view them at normal playback speed and also with a script like:
v1 = LSmashVideoSource("video1.mp4").Subtitle("video1") v2 = LSmashVideoSource("video2.mp4").Subtitle("video2") Interleave(v1,v2)
Use a screen magnifier too. Windows' built in Magnifier is good. You can zoom in and see the tiniest details.
