I'm still not sure what color the anemone is supposed to be.

Note also that a Dive+ logo gets put on the image. Still it's not bad for a freebie......assuming the 'video color correction' component produces comparable results.

Whether something similar could be implemented in AVISynth (by way of a scripted function/plugin) is beyond me. From what I've learned through this exercise, I have a sense that would require two parts - one (at it's core) a channel mixer (whether automated or not) to reconstruct the red channel as best (maybe guided by water depth absorption bias data) and then provision to adjust the color temperature. Feasible ? Only the AVISynth wizards here could say.
