How do I change and get SD to HD quality image on GIMP

[zabd1805]

Hi, everyone. So, mine for the resolution is 220x292 and it looks blurry to me. So, I tried to get right into it once and gave up for myself. Can you please help me by giving some hints and tips?

It would help if you describe exactly what you want to do with that image. It is blurry because of size (small) format (jpeg) and most probably some prior scaling.

Do you want to keep that size 195x259 pix? and maybe sharpen the image.
Does SD to HD mean you want a larger image? Plenty around in larger sizes Google search result see: https://tinyurl.com/y5z846zm
That will be better than upscaling your small image.

Can you give your Operating system and Version of Gimp. The questions are there for a reason, so that someone, somewhere, maybe can help you.

No, I don't want to keep the size like that. I want to sharpen the image and yes, I want a larger image as well. So, I'm on Windows 10 and the GIMP version is 2.8.10. If they still can help me out on that, that'll be great to give all the hints and tips. And needed it for converting too as well.

Do you have any particular reason for using Gimp 2.8.10? That version  is 5 years old.

My advice is unless you want that image you posted as a thumbnail then there is not much you can do with it.

When you scale an image up in any bitmap graphics application, it has to interpolate (guess) pixels. The same scaling down, pixels are thrown away. Either results in a fuzzy image to some degree.

If you are going to use game box covers then learn to search around the game sites. That link I gave has a slightly better image which I got from  https://tinyurl.com/y5s62hnw (these are monster long google search url's so I am using tinyurl)

With gimp 2.8.10 there are two standard tools for sharpening Fileters -> Enhance -> Sharpen  and Filters -Enhance -> Unsharp Mask  It is usual to use unsharp mask but for this image I think a regular sharpen works better. Looks like this in a Gimp 2.8.22



That image is attached. It is 770 x  1024 pixels. It would scale up maybe x2 but not much beyond that. There are plugins such as gmic_gimp http://www.gmic.eu which have filters for scaling and improving small images, however not that sure it  works with Gimp 2.8.10 

Whatever methods you eventually use, sharpening is the very last operation you do. Do all other editing before that.

OK, thanks. I will do that.

[zabd1805]

Hmm...I got it, but still no luck for me. It has to be very clearer, smoother, and sharper for better quality with no problems.

Can someone please explain this to me again, so I can see the video or the number of steps with freeze images for example?

and from earlier:

The basics, scaling and sharpening.

Thanks again, I'll do it on my own for quite sometimes now. ?
