Install SlowMoVideo on Ubuntu

SlowMoVideo is a free, multi-platform, and open-source application that allows us to create slow-motion videos from the footage. It examines the pixel rate and calculates the number of frames in your video. It also uses FFmpeg to read and write video files. You can easily load any video, in any format, that is supported by the FFmpeg and slow down your videos smoothly. Additionally, the motion blur can be added as per your choice.

Installing the SlowMoVideo is very easy on Ubuntu 20.04 as it is included in Ubuntu 20.04 standard repository. Moreover, we can download the SlowMoVideo’s AppImage file and run it on Ubuntu 20.04.

Open the terminal and update the apt repository with the command below:

$ sudo apt update

Next, install the SlowMoVideo with the appended command:
