Best way of upscaling 4:3 to 16:9?

[Magnus]

Hi guys,
I've yet to figure out the best way of upscaling my footage.
You might ask me why, but it's mostly cause in my eyes it looks nicer covering my whole screens when I watch my vids.
So basically for a upcoming video I'm using an anime whichis in 4:3 - 640x480.
And I'd like to upscale that to 848x480, which would be the best way of doing this?
What commands and filters would give me the best result quality-wise and so on?


Thankful for all response!

When doing upscales, nnedi2 is what you should use. Some sharpening after it might also help.
Either way, since you're talking about upscaling a 640x360 area, why not upscaling it to 1280x720? Upscaling by exponentations of 2 will result in nicer upscale, and it's what nnedi2_rpow2 does after all. All in all, my suggestion is:

Code: Select all

nnedi2_rpow2(2,2,3,true,"spline36resize",1280,720)
lsfmod()
fastlinedarkenmod(thinning=0)
awarpsharp2(8,1)

Slow but likely to give pretty much as good of a result as you can get.
If you don't have some of those sharpening filters, here are the links:
lsfmod
fastlinedarkenmod
awarpsharp2
Note that there are differences between these plugins and older version (eg: limitedsharpenfaster, fastlinedarken, awarpsharp), since there were various improvements, be it output or speed wise. Lsfmod is slower, but sharpens slightly better (the old one used to give me an odd banding-like effect in some areas, this one seems to not do that anymore), fastlinedarkenmod actually works for me now (the older one wouldn't want to work for some reason...), awarpsharp2 removed the green junk bug and changed a bit the parameters.

Thanks a lot mirko!
I will try it out, but first I need to know something.
And this WILL be a newbie question, but which folder do I save the new filters to?
Never downloaded any additional filters before.

C:\Program Files\AviSynth 2.5\plugins

Put the .dll or .avsi directly there, no subfolders.


BTW: That script should be used after you cropped the 640x480 to 640x360 of course.

Alright, gotcha.

Thanks!

woot this set works better than i expected though it would be good have some kind of smoother&deblocker it's a little "dirty" because of that in places
any suggestions?

After upscaling and before sharpening try to use fft3dgpu at light settings, perhaps these might do:

Code: Select all

fft3dgpu(mode=1,precision=2,sigma=1.5)

though after render it doesn't looks so bad O:
well thanks i will try it out i wonder i how will it look on mah 42" if my hdd will handle render of ful vid lol.

The best route to take is to set your project file to 640x360 and avoid the upscale. It always just looks tacky and noticeable to me. But if you can pull it off more power to you.

Not fucking up scaling?

Enjoy your craptastic quality on that.
