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.

VIDIFOLD Revision Notes

A list of all the notes from all versions is provided below.


Fixed nasty seq fault if attempted to use a mixer/effect dual plugin in Aux rack
Active plugin button label tweak
Fixed Global Pause display state (prob broke this when GKU was introduced)
Bus mode label is no longer clickable on main previews as I was always accidentally hit them!


Fixed: I broke the final output rendering in last release if bus had alpha


BUS slots fx plugins can now show parameter updates without needing a running layer
Added - plugin source selector parameter type now has menu popup (was defined but un-supported until now)
Reworked layer mixer again, so plugins which use layers can be more useful now
And as usual, gui tweaks / improvements





Improved Driver setup for trigger and toggle parameters
Fixed a missed until now low level bug in GUI system (wasn't causing much of a problem, but nasty when it did)
Fixed low-level alpha bug, hopefully the behaviour of alpha should be more consistent
Added menu button to Aux Rack
