Hello friends.I comment to know if anyone has this problem.  Before updating when the mark was still on the sensor, when recording 4k everything looked amazing, the sharp colors stood out, no noise in the video due to ISO. everything absolutely fine will leave video (mountains).  but after updating my 4k it is not the same, everything looks more grainy in the video, the colors are not so much, more noise appears in the darkest areas, the skies are not clear, etc ... I'll leave video ( sea ​​and clouds) both recorded in 4k, 30 fps iso 100  

if they can share videos in 4k, to make the comparison to know if my sensor is bad, or is the update that is causing this problem.

Firmware updates don't affect video quality.

If the second video is after updating, the issue is that your composition and exposure settings.
70% of the frame is bright, looking into the sun and glare on teh water.
30% of the frame is dark foreground.
The exposure is set for the bright sky and the contrast between the large bright area and small dark area is too much for the camera's sensor to be able to expose both correctly.
Turn the drone around and have the sun behind, lighting all of the scene and see how that looks.

this is another one before updating, no noise in the image, optimal quality and sharpness


and it lacks quality, noise in the image, grains are coarser



Do you think it is only a matter of exposure settings?

It's just the lighting.. doubt any firmware update changed the video profile.

Go and shoot a good example to check before you get over-excited over nothing

The first statement is not true in all cases.

There have been FW updates for other drones that affected image quality (usually for the better though)
I have not noticed differences with my M2 after updating, so I totally agree on the second part of your reply .

Is your exposure and white light balance set to automatic?  That can cause that as it is averaging everything out and adjusting as the light changes as you change your view. Try setting manual shutter speed and manual white balance......use auto white balance of a scene, note what it is using and than manually lock that in for that same location.  By doing this the exposure in a movie won't vary as you pan around. You can vary those settings for best results but the locking exposure and color balance it will give more consistent results.

There's no problem evident in those videos.
You are getting excited over nothing.
