Just giving you an insight from up-scaling/conversion:
If you are already aware of, then ignore my feedback ...
The reason why, there are bunch of poster doing it incorrectly ...
For instance 1280x720 [correct] vs 1280x960 w/c the enhancement is incorrect ...
That result in huge space capacity and abnormal Aspect Ratio output ... [16:9 widescreen | 4:3 fullscreen] ...
Resolution is an important factor to measure the visual quality of digital images, photos and videos. A higher resolution signifies the picture contains more pixels, which means it can display more visual information. As a result, a high-resolution picture is sharper and clearer than a low-resolution one.
720p = 1280 x 720 - is usually known as HD or "HD Ready" resolution
1080p = 1920 x 1080 - is usually known as FHD or "Full HD" resolution
1440p = 2560 x 1440 - is commonly known as QHD or Quad HD resolution, and it is typically seen on gaming monitors and on high-end smartphones. 1440p is four times the resolution of 720p HD or "HD ready." To make things even more confusing, many premium smartphones feature a so-called 2960x1440 Quad HD+ resolution, which still fits into 1440p.
4K or 2160p = 3840 x 2160 - is commonly known as 4K, UHD or Ultra HD resolution. It is a huge display resolution, and it is found on premium TVs and computer monitors. 2160p is called 4K because the width is close to 4000 pixels. In other words, it offers four times the pixels of 1080p FHD or "Full HD."
8K or 4320p = 7680 x 4320 - is known as 8K and it offers 16 times more pixels than the regular 1080p FHD or "Full HD" resolution. For now, you see 8K only on expensive TVs from Samsung and LG. However, you can test whether your computer can render such a large amount of data using this 8K ...
