Exposure Compensation for Bee Time Lapse?

Here are the results of my time-lapse-footage-to-date of my bees building comb in their hive box:

The time-lapse video is compiled from a directory full of JPGs via ffmpeg:

ffmpeg -pattern_type glob -i '*.jpg' -vf "drawtext=text='%{metadata\\:DateTimeOriginal}': fontfile=/System/Library/Fonts/Helvetica.ttc:fontcolor=white: fontsize=72: x=(w-text_w)*0.01: y=(h-text_h)*0.98" -y video/CombLapseWithTimeStamp.mp4

Despite I’m using a dSLR with fixed shutter speed and aperture, in a closed box, there’s still a lot of exposure variation throughout the sequence.

Can DaVinci Resolve equalize/normalize the exposure values throughout the video? It would be even better if that exposure value could be normalized to some region-of-interest, e.g. the static parts of the images that have no bees or comb.

Thanks!

The Blackmagic way is to buy Studio and get the Deflicker OpenFX.

Since you have ffmpeg, have you looked at https://ffmpeg.org/ffmpeg-filters.html#deflicker ?

Here's a Fusion way to go about it. This is done in an older/better version but the tools all work the same.

Ah, thank you! I was searching for anything related to "exposure" and didn't realize it was called deflickering.

I'm experimenting with this, and it does improve things in some cases, but it also makes it worse in other cases.

I also want to match the exposure value to some reference, so I think I want to try betheanimator's suggestion. But I'll keep deflicker in my hip pocket, as I'm sure it will come in handy in the future.

Thanks! It will take me awhile to grok this, but it seems like it's what I want to do.
