This projection quantizes pixels to monochrome values, decided by comparing brightness to a threshold.
The sample clip used is a stable scene, the threshold is varied to random values at random intervals with a smoothing effect between changes.
This video-based projection is a branch of the Loop repository.
Rapidly varying pixel values and motion physics constrained by the of holding a camera make video a good base for experimentation. No movement is unaturally fast, and the scenes are complex.
Loop projections use ffmpeg which is included and linked with the project at compile time resulting a lengthened build. Though not fatally long, build speed could be restored by separating video decoding into a separate process. However, sharing frames between processes is a potential bottle-neck and puts the projection in a similar role to the compositor of a windowing system.
Further work on using videos as textures Instead the video could be decoded in a separate process and exchanged via shared memory or a socket. This function is similar to that of the compositor component of a windowing system, so some research should be done first.
