explainer · general · evergreen · 2020–2022 on HN
Steve Mould explains motion amplification and video magnification, techniques that find tiny changes in video invisible to the eye and exaggerate them. He covers the MIT research and industrial uses such as diagnosing vibrating machinery.
Pointed to as an approachable layperson's explanation whenever video magnification or vibration visualization comes up.

I found this other video on the topic that I wanted to share. link and Steve Mould's layman's video ▶ this video
There is indeed research in doing that -- "motion magnification" visualizing vibrations in machinery: ▶ this video overview of research, and discussions on HN: link TED talk: link edit: TFA: > from the change of a single pixel’s color value over time, it’s possible to infer motions smaller than a pixel. > the researchers borrowed a technique from earlier work on algorithms that amplify minuscule variations in video,
Combining this with Motion Amplification/Video Magnification [1] could result in some very interesting visuals and applications for factory equipment. [1] ▶ this video Explainer Youtube video about Motion Amplification
I saw a Steve Mould video on this recently. ▶ this video The guy who used it seems to imply his version had a bit of 'special sauce'
