Requires Ubuntu 20.04.

Minimum Requirements: resolution of 1920x1080 for your primary screen, and graphics card with drivers able to run version 4 of OpenGL shaders and at least 2GB video ram. Suggest installing the latest graphic drivers and recommend the system uses an SSD Drive.

You will need FFmpeg installed. sudo apt update;  sudo apt-get install ffmpeg;

If you have trouble importing a file (e.g. mp4), you could review:
which amounts to trying this: sudo apt-get install ubuntu-restricted-extras


There is NO telemetry in this app, you don't need an internet connection to use it. If you have any issues you will need to report them. There are some notes available if you run ./VIDIFOLD --help

If you wish to report an issue or ask a question, please email

I hope you will get as much fun playing with it as I do.
