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.
