When starting to look at various real time video processing software like Isadora (VJ Tool), or openFrameWorks (C++ effects library), I found that I was unable to connect my Panasonic HPX 170 camera and see video in real time. I was always getting errors when connecting the camera, or when starting capture. I knew it could work because Adobe OnLocation and an application called WinDV would render a real time capture to the screen. So I figured there must be a variety of APIs involved here. Thus started my odyssey into figuring out how all this works. Continue reading "Panasonic DVCPro HD Live Feed" »

Visual Special Effects
I've been looking at various special effects with respect to motion control, motion tracking, camera tracking, 3d modelling, animation, LED lighting, with some possible real time interactions. I've put together a list of sites to which I have to re-visit once life settles down some.
- AdaFruit has various kits relating to Arduino, LED strips, and accessories. Another LED strip. Learning about them. My jumping off point: AusChristmasLighting. Strips in bulk, but the older style WS2811 IC, Alibaba.
- Robot Shop with Arduino YUN: mix of Arduino and Linux. They also have a Raspberry Pi touch screen.
- Sparkfun also has Arduino and Raspberry Pi modules.
- LRTimelapse and DslrDashboard: Using a tablet to control a camera and an Emotimo.
- Planetary Stepper: possible substitute motor for Emotimo stepper.
- Phidgets also has Stepper motors for the Emotimo (which sometimes is out of stock)
- Waterott has motor controllers for Pololu A4988 stepper motor driver. 3 axis stepper.
- To control the focus, zoom, and iris of a Panasonic HPX 170, I can use some Voltage Controlled Resisters off an Arduino. I'm looking at a Microchip MCP4361-503E/ST and a 20-Pin TSSOP and SSOP Evaluation Board.
- Fast C++ library for image and sound processing: IntelĀ® Integrated Performance Primitives (IntelĀ® IPP)
- Primitives like these could be incorporated into DirectShow filters in order to expedite processing. But this reduces the ability to be cross platform if running on more than just Windows is required.

Interactive Digital Media
Over the last few weeks, I've been delving into the world of Interactive Digital Media. This has included investigation into interactive environments, programming tools, modelling suites, supporting hardware, algorithms, plus a host of related and unrelated alley-ways.
