Using FFMPEG to adjust color tone in video

[MikeS]

In Adobe Photoshop I can do Auto-Tone and it improves the picture quality. Is there a way to do this in FFMPEG? I'm using a color curves .acv file to remove fog/haze, could the .acv also be designed to correct the color tone? Or is there another way using FFMPEG?

Here is a before and after using the Auto-Tone

ffmpeg seems like the wrong tool for the job.

I'm using FFMPEG to stream from the IP camera to Youtube.

There is color curves filter in FFmpeg. see curves filter documentation.

Ok I think I figured it out. When I created the curves file in Photoshop I was using the RGB slider. If I use the pull down and adjust the blue, I can get it to look like the Auto-Tune function.

I tried using the RGB blue slider and found it inconvenient. Lots of futzing around. I found that the presets did a better job anyway and gave a simple one step result, like Auto Tone. I liked the results from the Strong Contrast preset best but Increase Contrast was also good. ffmpeg result is identical to Photoshop:
