Feedback for a video mixing patch i've been working on



  • Hey everyone,

    I've been using Isadora for about two years now.  Mainly, I have been using it for VJ purposes.  This is a patch that I made initially for AKAI MPD, but expanded it to use with the M-Audio Radium 61\.  It works with 2 channels of video with 16 cue points.  The user can mix with combinations of HSL and Luminance Keys and also mix in a alpha mask 3rd layer for logo's, etc.  It includes tap tempo and the ability to multiply or divide the note by different "note" lengths (1/2, 1/4, triplet, whole note, etc).  I will probably change this section because I dont typically need as many choices for division/multiplication.
    Since I am quite new to the video world and Isadora is really the only program I am working with, I would really appreciate any feedback that might tighten up/clean up the patch, workflow, or even suggestions to add more creative possibilities.  
    I've tried to make comments to make more sense of some of the madness.  I also uploaded all my user actors.  Please let me know if you have any questions.
    Thanks so much!
    I'm using the Mac version of Isadora 1.3.0f22

    Hi Trek
    It looks like you have but a lot of effort into the patch, and have managed to get a good variety of features up and running.
    My main suggestion would mostly be in regards to modularity. As it is the patch is complex looking, mostly due to being a bit of a fish net of patch cords. I would suggest trying to isolate functions (more than you have) to create additional user actors (the ones you have are definitely helping to clean it up).
    I would also suggest, if you have not to go through my 'video sequencer' tutorial.. it isn't perfect, but does give a decent approach to embedding components logically to clean up a patch, and in the end the sequencer is a rather cool little tool I use for VJing rather often.

    After that I would suggest taking a look at the inners of my SYST3M video mixer, I have work hard to keep it clean and modular. Again not perfect, and I would change somethings if I were to start over, but there are some good tricks to be learned with a little snooping around in there.

    Feel free to contact me with any questions you might have.
