Realtime Communications and Audio/Video Processing
Kevin Packard
The Video Appliance is the latest project created from blackfrog software’s PComm Framework. The Video Appliance integrates with any existing telephone PBX, and adds IP video conferencing in parallel with the telephone call. Use your phone normally: call someone who also has a Video Appliance and you’re in a video call. The Open Source PBX Asterisk powers the back end. It’s simple to set up, and is as simple to use as picking up the phone and dialing.

Current Projects
Telecine Film Transfer - a free open-source tool for stop-frame transfer of film to the digital miniDV movie format.
The Telecine Film Transfer tool eliminates jumping frames and other unpleasant side affects when capturing projected film with an unsynchronized camera.
1. Project 8mm or super8 film at 5 frames per second.
2. Capture the projection with a standard digital camcorder.
3. Post-process with Telecine Processor into a pristine 18 fps movie.
Video Appliance - integrate IP video conferencing to any existing telephone PBX. Use your phone normally. Call someone else who also has a Video Appliance and you’re in a video call. Built from the PComm Framework.

Telecine Film Transfer - a free open-source tool for the stop-frame transfer of film to the digital miniDV movie format.
8mm or super8 film is projected at 5 frames per second. This is accomplished with many film projectors, but better results are possible with a device like the Video Work Printer from MovieStuff.tv
While projecting the film, capture the projection with a standard miniDV digital camcorder.
Post-process the captured movie with blackfrog’s Telecine Film Transfer. The result is a pristine 18 fps miniDV movie, ready for processing in any miniDV-aware application, including Apple’s iMovie and iDVD applications.
