Best settings for De-Flicker

[Pierre Jasmin]

Thanks for the example

Here’s a few ideas, and screenshot below:

1) It helps to set Global Color Reference Frame(s) – when levels change so dramatically
2) Because it changes so much from frame to frame, you probably need a wider time window
3) That said, the Timelapse plugin appears to have issues with the deep blue sky with flashing clouds… seems to reveal some compression block semi-related artifacts. That’s why I did an alternative setup to compare using the HiSpeed plugin. Note I use the Refine mode – the trick is to look at frames where some object appear and disappear with Refine Visualize checked and set the Refine Threshold to as high as possible so Red still covers these objects. The threshold will sort of create a max amount of deviation from original.
4)It’s also possible to combine the two techniques (and use smaller time window for each pass). As a simple example of that, using the setup I added here, if you set the time window to 0 in the Time Lapse one, you can turn on and off to see the pre-deflicker effect Global Color Correction has.
