Is there a way to fix Auto Iso caused brightness fluctuation?
Hi there.
The issue is that I shot a classroom video with a speaker and static ligths, but since I forgot to set Iso (it was on auto), the brightness is adjusting itself when the subject moves and it doesn’t look good. I could try to balance it out manually by keyframes and brightness adjustment, but that’s a hell lot of work as the material is more than 3 hours long. Is there a way or some plugin to set a level for the brightness to have all the frames adjusted to the same setting?

Hey Jaanus,
What you want is to even out the exposure?
I would suggest that you head over to RevisionFX and look at Color Genius.
“Automatic exposure compensation, Embedded anti-flicker unlike other machine-learning solutions.”
They have a free trial for Vegas:
https://revisionfx.com/products/colorgeniusplus/vegas-pro/#features
The purchase cost is at a fair price.EDIT: Should have added that you might want to do your 3-hour video in chunks, rather than the full 3-hours in one go.
With the added help that RevisionFX has a dedicated forum right here on the COW, which is often visited by the people programming the software:

Hi Mads!
Thank you for your reply. I finally had time to check it out and looks like Colorgenius is not able to fix the problem. It can even out the exposure of brighter and darker areas in a frame but not general exposure changes over a longer sequence of frames. At least that’s how I understood. You helped me to delve in to the problem more seriously though and find the solution that works. That is Davinci Resolve Color stabilizer effect. I didn’t try it out personally, but the youtube tutorials that are out there are exactly fixing the problem. Could not find any alternative for Vegas pro that works the same. Looks like I have to either fix the issue manually, or then go for Resolve, if it’s worth it.

Hey Jaanus,
Admittedly I did not think outside the Vegas box 😀
But if Davinci works for you, then that is another option.
You could split the clip in the middle of an exposure change and add a very long dissolve between the one with the right level of exposure and the under-exposed part. Then adjust the under-exposed part to match as best as you can. Just make sure to do same at the under end of that isolated part. Or the rest will look burned-out…
Should not take too long to do.
But Davinci, although with a learning curve, will always be helpful for you to know how to use.
