#Warpsharp davinci how to
My second question is how to handle this, workflow wise. John, (or anybody else who knows the involved functions) could you possibly tell me which variable(s) I should be tweaking, and which way, up or down? I'm just not there yet, or even close, with avisynth.īut I do absolutely love what his script does for my files, 90, 95, 99 percent of the time. But to be honest, I was shooting in the dark. I also tried adjusting the denoising strength, as well as the bvec and fvec settings. But to my eye, it still seemed to increase the graininess just a smidge. The closest I came was a reduction of it by putting 0.0 ias the sharpening factor instead of the given 0.1. I dug around in his script some last night trying to see if I could smooth it out some. I'm sure John has run across things like it a time or two before, and he probably knows just exactly what values to tweak where, by how much, etc., to deal with it. It's me.Īnd yes, this is the same section of film that I first approached you with, many months ago, about just a degraining script to treat it with. The issue is I am not fluent enough with it to know what to adjust to deal with a sub standard source. Or maybe the halo effect is what makes me think the grain is larger.īut don't get me wrong, the script is amazing. What I see is more grain than what was there originally, and I think it is the sharpening maybe, that puts a sort of halo around it. What I see happening is the already visible grain is being exaggerated by the script, and then sharpened.
Johns script is so nuanced, that when it runs into something like that, it can't be run at the default settings and must be adjsted. On the vast majority of my transfers, which were good already, it has taken them to another level.īut there are a very few, that because of the way they were shot, (probably high grain, but "fast", film) do have what I feel is excessive grain. What do you use to "rip" the grain from a show? Are you using grain matching tools in After Effects or Resolve? I know you can sample regions of a grain pattern and use that for VFX matching, but I haven't heard of a freeware tool to do this.I have been working with John Meyers 8mm restoration script, and it is truly amazing. I must confess, I'm a bit out of the loop with recent encoding tools (Indeed, I had to brush up on vapoursynth and python to get the batch encodes going). With Big-O, I actually went into DaVinci Resolve to use a proper film emulation, and the results work better there, but I wanted something a little more automated here. I just wasn't happy with the result, not to mention it bloated the filesize. Topaz seems to inherently remove quite a lot of noise, even with the denoise sliders turned all the way down, so it's somewhat unavoidable in the process, BUT, I did try adding grain via Topaz in initial tests. It's also not a great scene to test since the stock footage sequences are at least a generation away in terms of film stock (you can see the color differences right away).īut I do see get what you're saying, and yeah, there are plenty of shots where the upscale looks too clean, I'll admit that.
