It's just my opinion, but to me, upscaled SD is obviously only a fake HD. I can take a 640x360 video, play it at 1280x720, and it'll look like...640x360. Maybe a little blurrier.
yeah, that's true, when you do a simple basic 2x, without anything else,
but who would do that????..
but when you do image processing algorithms on it, you can effectively improve it..
(not with detail) ...but with other effects.. so you run it on the series of images,
and the recombine them to video..
=========================
this is for images

Reshade
This is the newest method from the ones I mentioned. It permits enlargements of up to 200% without losing any quality. This means that even an experienced photographer would have a hard time picking an enlarged version from an original photo.
=========================
this is for video: rescaling SD -> HD

Two algorithms to rule them all.
ReSizer 2.0 has two algorithms. Well, it really has four, but only two of them are for creating your final footage. Use Best (Smooth) and Best (Sharp) for making SD into HD or just resizing the footage in general. When do you use one versus the other? That's pretty subjective but we have given a few suggestions below. The No Filtering and Fast options are for your pre-work.
check out the examples like:

Video Enhancer can convert your video to any resolution with superb quality. Super Resolution is a technique of increasing images or video resolution. For each processed frame it uses information not only from this frame but also from other frames. If picture in your video doesn't change too fast, then information from several frames can be added to create a picture of a bigger size. No algorithms of ordinary image resize/resample can provide this quality just because there's not enough information in one frame. Here is a couple of examples:

Instant HD up-converts DV video into a variety of HD video formats. Choose from a list of preset resolutions to easily integrate DV video into your next High Definition production. When scaling from standard definition (SD) to high definition (HD), Instant HD's algorithms generate the missing pixels with integrated sharpening and anti-aliasing for sharp, clear results inside your favorite video application.

there are plenty more out there..
has no one tried anything like that?
that's why i love image processing (i'm a math major, but never got to use
all those cool things in my jobs)..
there ARE ways of upscaling the image and making it look better..
you just have to try them..
later
