Demonstrating key-screen application — 2023 update. A quite old technique, yet remains a staple in the film industry for small and large-scale special effects, and which can transform static single presentations to be valid across different audiences – all accomplished during post production rather than re-filming.  Examples from serious to fun.

2023 new update to our masking and keying experiments.  Two methods described here to rotate wheels on a vehicle animation. One fascinating discovery for filming small scale models is the use of a computer screen instead of making a single colour physical screen. We use a legacy title background in Adobe Premiere to generate the best colour for the job. Full description of the two methods with advantages and disadvantages of each.
