720P 4K Converter: Convert 720P to 4K Resolution and Vice Versa

Step 1: Add 720P or 4K Video Files into the Program

Launch WonderFox HD Video Converter Factory Pro after installing it. Then open the “Converter” window and click on “+ Add Files” or “Add Video Folder” button to import the 720P videos or 4K videos into the program. You can import multiple files simultaneously into the converter as it can batch process the conversion at once.

Step 2: Choose an Output Format

If the displayed format image on the right side isn’t the original format or you want to change the video format, you can press the format image and select one preferred format under the Video tab.

Step 3: Adjust Output Settings

#1: Convert 720P Video to 4K

To convert videos from 720P to 4K, you can directly go to the Quick settings and move the slider to 4K resolution. You can also go to the format image and choose “4K(MP4)” or “4K(MKV)” under the “4K/HD” section in Step 2.

#2: Downscale 4K to 720P

If you want to convert 4K videos to 720P, you can also utilize the Quick settings to quickly set 720P resolution for the 4K videos.
Tips: You can also press “Parameter settings” to modify the video settings if you want to specify a video encoder, change video bitrate or customize other parameters. Here you can also change the video resolution to 1080x720 (720P) and 2560x1440 (4K).

Step 4: Start the video upscaling or downscaling process

Specify an output path by clicking the inverted triangle button, and then hit “Run” to start the conversion.
