Trying to Glitch and Break Video Exports

Hello all!

So I was working on a design piece the other day and was recording my process. I then took the video and sped it up in Premiere Pro. The pictures included show what happened with the export of the video. It seems to me that the export went wrong and resulted in a glitchy/datamosh video. 

This has only happened to me once but I actually LOVE the error and the result. I was wondering if anybody knew how I could consistently reach this effect and replicate it. It seems very ironic (I know) but I love the result and want to mess around with it more. Any and all ideas are welcome, thanks!
