• Import the lookup.png (the uncorrected File) into After Effects, Syphon it out (512 x 512 px) to the GLSL LUT Shader "video in 2 Input", and apply (in After Effects) any sort of color correction (LUTs, Lumetri Control, Curves):

    As soon as you are happy: Export as uncompressed PNG and apply it directly.

    Full Color Correction control in Isadora! Greatness!!!

  • Thanks @mark for your quick response, also @jhoepffner and Kave for your links. Amazing!

    I also agree with you @jhoepffner, it would be very useful if we could use .look files directly to Isadora.

    Thanks!

    Great thinking, Keve.

    For Windows users, and perhaps even Mac users, another way to get that from After Effects (or Premiere) into Isadora is via NDI and NewTek's NDI plugin for CreativeCloud combined with the NDI receiver actor in Isadora.

     what actor is that, do you mean syphon2NDI?

     Not in my case, 'cause I'm on Windows. Spout to NDI comes with FFGL Plugins which appear as actors in Isadora. I don't know if Syphon2NDI does the same.


  • I strongly support the idea of using .cube files ( 3d LUTs ) directly in Isadora.

    These files can be created with the free version of DaVinci Resolve, with a very good user interface to archieve color grading.

    DaVinci even offers a "Live" option, that allows people owning Blackmagic Decklinks with In/Out ports to make color grading with ~1 sec. latency.

    You can then export the 3D Lut file corresponding to your color grading, and apply it realtime with any solution supporting .cube files.

    I am using this workflow on a production actually on tour, where we create or LUT files in DaVinci, and then load them into dedicated hardware.

    As this hardware coste ~1500€ for grading one video signal, having the capacity to load it into isadora would be great.

    @mark  : the decoding of the file can be "long", having the possibility to load a couple of LUTs in an actor that decodes them on startup, and then allows to switch between color gradings without any delay would be great.

    Best,

    I think your freeframe plugin comes from an other source than the isadora installer ( I saw one on resolume's forum ).

    This might be the reason why other people don't have it ( I don't have it with a fresh windows isadora install ).

    Yes, just to clarify, the freeframe plugin comes as part of the Spout to NDI package, and appears as actors [NDIreceiver and NDIsender]  - in Isadora.
    Am I wrong to refer to them as a 'actors'?

    I’d say technically no, because everything in the Workspace is an actor, but they’re not Isadora actors (correct me if I’m wrong). For the sake of clarity, I’d probably call them freeframe plugins, 3rd party plugins, or 3rd party freeframe plugin actors, etc. Just calling them “actors” might make folks think they’re native Isadora actors. Just my two cents.

    P.S. Could you please provide a link to this Spout to NDI package? I’m always collecting every tool I can get my hands on.

    Thanks Lucas, here's the link to the package with includes the NDIreceiver and NDIsender acto... FFGL plugins. For Windows only, obvs. Instructions need following carefully to install the FFGL plugins themselves. There is a Syphon2NDI available out there. Don't know if that also has FFGL plugins which play nice with Isadora.

    NDI is 64 bit only on Mac OS, thus it is impossible to use 32 bit plugins to interface with it. Syphon gets around this because it allows you to send video between 32 bit an 64 bit processes.

    These applications for Mac OS allow Syphon <-> NDI
