-----------------

Tested that script last night on Record of Lodoss War. Very messy anime, lots of interlacing and quite noisy. Results are quite good and comparable to SSHiQ. And much much faster than SSHiQ! It save around 30 minutes/pass. more testing I guess but I think Record of Lodoss is like a benchmark.

Thank you Vlad.

isn't the result too much blured/smoothed ?

hmm not really. seems alright to me. I used matrix 0 as it blurring is less compared to 1. That's according to the readme. actually the convolution3d parameter values were suggested by vlad himself.

@jarthel

I don't claim to have a perfect knowing about the use of Convolution3d so my suggested settings works for my tests and my taste at least ;). I'm happy to see they works well for you.

Finding good parameters to Convolution3d or any noise reducer is always a pain. I'm still working in a way to quantify the noise of a movie, I hope to find a good and reliable way to do it..... :sly:

Convolution3d V1.0 should be out this weekend. The changelog won't be very long :
- a little more optimizations (thanks to Sh0dan) ~2-3% (already done)
- comment the code (to do, I really don't like that)
- update the doc (75% done)

wahoo ^^
2-3% :D

Yep better than nothing ;)

This is great Vlad.

I have nothing against sh0dan but instead of helping others, why can't he help himself and optimize SSHiQ. :)

Is a good idea put the best values for diferent purposes. By example: For less bitrate need use "convolution3d(x,x,x,x,x,x)"
For anime use "convolution3d(x,x,x,x,x,x)"
For DV use "convolution3d(x,x,x,x,x,x)"
For VHS capture use "convolution3d(x,x,x,x,x,x)"
For noyse video use "convolution3d(x,x,x,x,x,x)"

Post here you favorite values.

[sh0dan]

I think it could be a good thing for us newbies for it to have presets, like:

convultion3d(preset="dv")
convultion3d(preset="vhs")

etc.

err, request request \o/

can we please have a custom .matrix file?

and one more, can you please make Symbolic parameters? it is piece a cake to implement and rally improves readability and makes tweaking easyer.

[vlad59]

@Sh0dan

Yes of course, I can do that.
But I'll have to ask some help of other people as I'm not an analog or DV encoder. So I have almost no experience with these material.

@OUTPinged_

Custom matrix is on my todo list. It won't be so easy because my two actual matrix are hardcoded to have more speed.
It will be for the 1.1.

About Symbolic parameters, I'll add that in 1.0.

[OUTPinged_]

vlad, a nessesity of custom matrixes is questionable.

maybe add unoptimised routine for a start, it can be unworthy.

as for symbolic params, that is a good news :-)

i agree ;)

[jarthel]

Is there any other way of controlling the smoothless strength aside from Matrix 0 or 1? Thanks vlad :)
