Using Command Prompt to Adjust Colour

I try to add eq filter “eq=gamma=1.4:saturation=1.2” as an argument to “-filter_complex”. But it returns:-

No such filter: ‘eq’
Error initializing complex filters.
Invalid argument

I wonder how I can rewrite the export command so as to adjust the colour while upscaling with veai_up?

FFMPEG for VEAI has limited filters and codecs due to the GPL license.
You can check the available filters and codecs with “ffmpeg -filters”, “ffmpeg -encoders”, etc.
" eq" was not available.

The only way to deal with this is to use a limited filter, export to ProRes etc and apply a color adjustment filter again, or use the pipe function to connect the two.
