### Installation for BSD/GNU-Linux systems:
|
||||
|
||||
- Copy the presets to ~/.avidemux6/custom/
|
||||
- Copy the presets to ~/.avidemux6/custom/ or ~/.local/share/avidemux6/custom/
|
||||
- Copy the shader to /opt/rk/avidemux/ (or edit the preset to set the path)
|
||||
|
||||
Or just run the scripts install_gopro_8:7.sh and/or install_gopro_4:3_maxlens.sh
|

Or just run the script install_gopro_8:7.sh
|

_For commercial OS's, figure out the paths yourself, then edit the presets to fix the path to the .glsl files_
