I was wanting to know if anyone is aware of a GUI tool that mimics or is similar to the eq video filter parameters in ffmpeg. The eq filter is used to set brightness, contrast, saturation, gamma, etc.
I have a general sense of the parameters and how to control them at the command line...however, sometimes having a GUI-equivalent for such a tool can more easily/quickly allow for fine tuning or adjustments to the 8+ "knobs and switches" for ffmpeg's eq video filter.
I did find a plugin that's installed as part of Avidemux that's pretty close to ffmpeg's eq filter -- in Avidemux it's called MPlayer eq2 -- but the results displayed in the preview window in Avidemux don't match the results I get when I transfer the syntax over to ffmpeg.
Does anyone have any pointers or ideas as to how to more easily manage changing the various eq parameters in ffmpeg?
