high definition
how can I make my images HD (high definition) in Gimp? like there are HD TVs I want to make my images have an HD look to it. I know it is possible to convert SD to HD because I've seen old sports games that were played before HD TVs were invented and the game was converted into HD. although it is not the same as if it was originally recorded in HD

whether the image looks like a SD to HD conversion or looks pure HD, it doesn't really matter to me...

how to I make my images look HD?

RE: high definition
You are not comparing like with like. HD and SD are video standards and the frame sizes equivalent to a graphic image are (for NTSC)

from 1280x720 to 1920x1080
SD is 720 x 480 (as for DVD) Widescreen 16:9 is acheived by hardware stretching the image in the DVD player. Motion covers up a lot defects.
Some old games probably less than this maybe 360x480

So you can see that video is a much lower definition than even a modest digital camera provides.

Scaling up an old video, is much the same as an image, never very good.

If you want HD images, start off with that size or larger and scale down.
