I been filming some smoke trails against the green screen today for my upcoming “Care Home” short film [working title].
The smoke film is 2 mins long and the final clip will be 4-5 seconds, so I have plenty of material to make 3-4 plume copies from different time stamps.
Below pic: The resulting smoke set on transparent background. The chroma-key tools in after effects are very effective for controlling transparency on a film.
Below pic: small plumes of smoke will come from between the fingers of one of the residents…
