I see two new checkboxes in the Visual Deflicker dialog, but I haven't been able to find out (from video or written tutorials here on lrtimelapse.com) what they do. Can anyone point me to the answers? Many thanks in advance for any insights.

Constant will use a straight horizontal line for reference as opposed to the smooth green line that follows the luminance progression. This can be useful for studio work where you need to deflicker to a constant, not changing luminance.

Increase Rating will increase the rating from the sequence (for example from one star to two stars) after deflicker is done.

thanks very much Gunther, much appreciated.

Have you explained this elsewhere? I apologise if I didn't search thoroughly enough (but perhaps somebody else might stumble on this thread, and would find that info useful).

Cheers!

Chas
