Hi all
Is there any possibility of a warpsharp visual filter? The warpsharp filter (as seen in virtualdub) can create tremendous images out of the native small snes image as seen in this video:

from my understanding, the video was created with the avi-output from an older snes9x version, resized and was applied the warpsharp filter.

So, could it be possible?

Greetings!

It sure looks pretty similar to HQ2x. I mean, WarpSharp sure does very well for cartoons, but SNES games (and in particular, that Terranigma intro) use a lot more texture in each scene than, say, Neon Genesis Evangelion.

As far as I know, the only SNES emulator that allows pluggable third-party video-filters is BSNES; if you can pick through the warpsharp code and port it to the API that bsnes uses for filters, you could use that.

Very interesting, got some screenshots from HQ2X-B and WarpSharp:

To me the warpsharp screens look really neat, maybe the overall quality can be improved by applying it directly in the emulator. Someone should give this a try

I've been trying to track down how that video was made, and how WarpSharp works. Reading the comments on the video, there were multiple filters used in VirtualDub to create that video, not just WarpSharp. I'm not sure you could get identical results in realtime.

WarpSharp is used to eliminate blurring and halos around hard edges, like you sometimes get in hand-drawn animation. It may have some beneficial effect on SNES images, but only after using some method to blur the image initially.

Hey

Do you mean there is something essentially different to just applying the WS-filter?

I tried to find out and wrote a message to the guy, he seems to resize and "remaster" a lot of stuff on his channel. I may have misunderstood things because my lack of knowledge of filters and stuff, but as far as I could read out of it, it was resizing and applying the warpsharp method.

I could post the guy's message, it's in German though.

The main problem is that the only C/C++ implementations out there are avisynth or virtualdub filters, both released under GPL2, which is incompatible with snes9x's non commercial license.

@SparroHawc, think you are right. I have tried to resize a Snes9x screenshot with the warpsharp filter, to wsharpen and resize, use the included warpsharp-resize filter and the results look horrible.

I have also tried to do a warpsharp over filtered screenshots, I tried them all there is on v1.52, but nothing looks even close to the video. And I'm talking here of resolutions of something like 1280x800, the video states that it's running at 2048x1536... That's insane...

At least, wsharpening the original sized screenshot looks pretty neat, so there seems to be something to it.

Well, if he's running at this resolution, he's probably pixel... quadrupling?

He -might- be starting with something like Eagle Super Sai and -then- warpsharping it...
