I assume you are talking about the blown-out sky? You could use a luma keyed to perform a sky-replacement (introducing an image of a sky with more detail and then tracking adding motion to it using tracker data from a distant object, maybe - there are YouTube videos showing complex sky replacement).

Is this what you are asking about?

If I follow the drawn arrow, I think it's the area under his cap.
This can be solved with a soft mask and by adjusting the exposure or in the HDR palette.

Good one! I was looking at this on my iPhone - my old eyes didn't even notice the red arrow, lol.

And next time use a matte box with a French flag (and maybe a lens with better coating).
Now that the cat #19 is out of the bag, test it as much as you can and use the subforum.

I was gonna say... the problem looks like lens flare and overexposure, which is rarely a good combination. This is trivial compared to the blown-out sky.

I have no idea why so many people overexpose digital material -- it's pretty maddening, and it's a constant problem in post. Film was a lot more forgiving in the old days.

Barring adding some lighting on the subject, a reflector would have helped a lot here to balance the exposures between the shadow and lit sides.

It's a matter of getting to really know your camera equipment by extensive testing, using a waveform scope and watching out for clipping. In my relatively limited experience, this holds for raw video as well as anything else. It is better to underexpose a little if there is a danger of clipping and deal with noise later if necessary than to overexpose and clip the highlights, where there is no hope of recovering detail.

Thanks all for replying, this footage taken from sony A 6300 with s-log3 profile. Unfortunately the footage look like over highlight or over exposure or backlight or whatever and the Cameramen doesn't use relector or whatever.
All of the footages are like this. Masking and tracking are really pain, and it will comsume time with hardworking.
I'm trying the best i can for getting rid of this problem :cry:
