    Gradient Mapping

    by yirehmail » Mon Dec 03, 2018 4:58 pm

    I would love to see if madmapper can do gradient mapping like photoshop (https://www.behance.net/gallery/4567978 ... nt-Mapping).

    What I would love to achieve is something like this video

    but with a live camera input for concert use.

    you can do this very easly with a shader fx.
    it is just color remapping , or using a LUT.
    we'll try to add it in the next update

    I've been using MadMapper a lot lately to preview video files because it's better at playing back than QuickTime. There's also better controls obviously. I had a thought today: wouldn't it be great if I could apply a LUT or use something like Lumetri live? With my Blackmagic Mini Recorder, I could get a rough idea of a Rec 709 look using MadMapper - or I can take the "raw" 60FPS footage and play it back at 24 FPS (approx 40% of speed) and apply a LUT there too. Is it possible?

    you should be able to do this in madmapper 4 using the heatmap fx:
    it take 2 colors (gradient) and remaps them to your surface colors.
