3 Ways to Convert 720p to 1080p Video with the Least Quality Loss

By Cecilia Hwung | Last Update:

Many people want to convert a video from 720p to 1080p to playback the video on a larger screen; some need to merge a 720P 120fps video into a 1080P project. 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.

Prepare 720p videos on your computer. Open the software and click "Video" on the dashboard. Go to the Video window, and click +Video to add one or more 720 videos from your computer.

Step 3. Set high quality options.

How to Convert 720p to 1080p in Adobe Premiere

Adobe Premiere Pro uses a simple algorithm to upscale your video. Typically it stretches the image out to the edges, and then interpolates back to fill the holes by adding pixels to the original pictures.

Step 1. Download and install Premiere Pro.

Go to Adobe official website to download and install Premiere Pro. But this program is very large in installer size and is CPU-consuming. Please make sure your computer hardware is sufficient.

Step 2. Set the Sequence Presets.

Create a new project > go to File > New > Sequence > Sequence Presets. Choose a 1080p output option (for example, DSLR 1080p24). Set the frame rate and aspect ratio the same as your source file.

Step 3. Set to frame size.

Find Edit on the top menu bar, choose Preferences and click Media, click 'Set to frame size' under Default Media Scaling.

Step 4. Import source video and upscale.

Add your source 720p video into the project, drag it to the timeline and let it scale the video.

Step 5. Export the video.

Do some other settings according to your needs. Render your video and export it.

Notice: Since Adobe Premiere upscales your video in a simple way, your result file may have blurs or noises. You can use Super Resolution Plugin or 'details preserving upscale' effect in After Effects. Or, you can use the unsharp mask in Premiere Pro to improve the blurred part. Or, you can turn to a better 720p to 1080p converter like VideoProc Converter.
