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

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.

Binary releases are available. Use VideoLab 1.0 for older Windows (Vista or 7) and MacOS systems.
