But is it possible to convert 720p to 1080p or even 4K resolution without looking pixelated or at least making the quality close to a true HD?

Virtually all recent smart TVs can upscale your low-resolution content to fill the entire TV screen. If you want to upconvert a video on your PC, you need a proper video converter.

There are many video resolution converters. But most of them will not make the image quality better, and some will make it even worse.

The article will recommend 3 feasible ways to convert your 720p SD video to 1080p HD video without losing much clarity.

How to Convert 720p to 1080p in VideoProc Converter

VideoProc Converter is a professional video resolution changer and video quality enhancer software. It can upscale your videos without hassle and guarantee the least quality loss. It mixes different interpolation algorithms, including:

  • Nearest neighbor interpolation: to sum up, it is to add and to guess. First it adds a heap of “blank” pixels to an image, and tries to guess what each blank pixel should be filled with based on its 4 adjacent pixels.
  • Bicubic interpolation: it is to add pixels to an image and take on a color based on the 16 nearby pixels. The main purpose is to smooth the color and make the added pixels look as soft as possible.
  • Bilinear interpolation: differently, it only checks the two neighboring blocks. The main purpose is to make the image look sharp.

Now, please download VideoProc Converter and following the steps.

Step 1. Input your source 720p video files.
