Timelapse each frame equalisation

I shot a timelapse sequence with my Canon DSLR, convert files to DNG, then import in Resolve 11. It was in a small courtyard between buildings. The camera was on aperture priority, under a changing cloudy sky, so some shots are a little brighter than others.

Is there a way to make each frame's brightness even?

if you are in resolve 12 you might try the "shot match" feature, being a timelapse it "might" work.

A lot easier to use LRTimelapes and Lightroom. It has tools to specifically deal with this type of flicker.

Yes.... but is another software altogether...

Sometimes you need to use the right tool for the job.

Looking at how some "deflicker" plugins work, I am wondering if turning Median (Noise Reduction) Filtering up to the nuts would have an analagous effect integrating adjacent frames, if you didn't want to deploy (purchase) a specific Ofx transform.

Digital Anarchy "Flicker-Free" will eventually be available as an OFX plug-in:

For now, use it in After Effects and round-trip it back to Resolve. The problem with trying to fix flicker on a frame-by-frame basis is dealing with non-linear flicker that only affects part of the frame.

I did some quick fixes for a few time lapses using a quick averaging function. It smears the motion a bit but the timelapse flicker is very subdued. Just duplicate the clip on three or more layers layers, offset them one frame each, and set opacity to 100%, 50%, 33% etc. bottom to top.

Thanks for all these ideas guys.
The Anders Holck Petersen solution is a clever one, but Adam Roberts is right, using the right tool is the key.

"Good workers uses good tools", like was saying my teacher when I learned typesetting, back in 80ies.

using the right tool is the key.

So, right away I ran into a line-frequency beat on a practical lighting element in a drama, so it was "on." The MedianNR approach makes for a very noise-free flicker... but doesn't fix the flicker.

What worked was the BCC restoration package "deFlicker" using the eyedropper to qualify the offending element (because it did not affect the whole frame, as a timelapse exposure presents) and then worked through analysis modes (RGB worked). It adds a "zero" to the render time... but happy client, beat the deadline.
