Videolab is an educational software piece that teaches and lets users experiment with concepts of digital video technology. It can be used standalone by students or as a lecturing tool by instructors.

Videolab includes four modules, teaching and letting users experiment with:

• Picture aspect ratio;
• Progressive and interlaced scanning;
• Luminance, chrominance and subsampling;
• Color depth.

Video can be captured from the webcam (if detected) or loaded from a file.

Videolab was developed as part of my early Digital Media PhD research. We made a small case study of Videolab's guided application in the classroom.

Latest builds were compiled with Processing 2.1 and tested on Windows (known to work from Windows 7 to 10.2004) and MacOS (from 10.6 to El Capitan), but may work on other systems as well. Videolab uses the sDrop library by Andreas Schlegel.
