I started off wanting to recreate the effect within Earth, Wind, and Fire’s music video for September. In the end I did something a little bit different, but still really cool. I used Chroma Keying (or greenscreening) to play a delayed version of a video behind the subject. It ended up making a really cool effect that I would love to explore more, both with different greenscreen footage and even footage without.
For my project, I worked with data-moshing a video loop of a pinecone time lapse. Data-moshing takes advantage of the way video files are compressed, and the glitches can be layered by repeating the process with each loop.
I tried with both starting from the pinecone image and starting from black. Starting from the pinecone created a more glitchy image at the end; starting from black led to more distorted colors at the beginning.
I used the technique of I-Frame deletion which you can read more about over here.
