Currently use QC to make custom layers for Bonix TV - a vision mixing kind of application for OS X with a kind of QC stack of layers, each layer being a composition with published ports and some protocols for data types. Also generate sports graphics and twitter feeds and so on for video score boards at large sporting venues.
Spent a few years learning Quartz Composer as my way back into coding from a decade away doing design related work. Film, graphics, studied Architecture for a few years and got involved in publishing then film. Now moving into front side web development. Hope to get into app dev with Vuo and rapid app prototyping.
The main limitation as I see it is that if you build FX plug-ins in Vuo (and this applied to equally to QC) is that if you just port it directly you are limited in the UI interface tou can have. It takes extra code, in Xcode to build some of the sophisticated UIs which some video effects plug-in deploy. But if you’re ok with hard wired input ports then I think why not? Hard part is doing something genuinely original/new to the platform, there’s a bunch of low cost transition plugins already for example.
if there’s a way to execute a bundled shell script reliably then “pwd” terminal command returns the URL of current directory. Might need to set permissions of the script to be an executable with relevant admin permissions. (Be careful).
Put the URL into a text file and open the text file in Vuo.
