However, the determination of viscosity often relies on specialized experimental equipment, offline experimentation, or invasive procedures, in particular when required in extreme conditions such as at high temperature, high pressure, and in confined or corrosive environments. Here, this study proposes and validates a fast and simple method that mimics the intuitive perception of liquid flow within a quantitative framework. For this, this study employs digital video observation to derive quantitative values of the shear viscosity of liquids, with high precision and rapid acquisition rates. The technique involves capturing liquid dynamics after minor mechanical stimulation. Processed imaging data are indexed by similarity and referenced to a digital database generated with a finite element model, from which values of viscosity are obtained in line. The approach is tested on water at room temperature and on a high\u2010temperature glass melt. Covering a viscosity range of four orders of magnitude, both yield convincing agreement with tabulated reference data at low computational cost.<\/jats:p>","DOI":"10.1002\/aisy.202500297","type":"journal-article","created":{"date-parts":[[2025,6,22]],"date-time":"2025-06-22T22:54:52Z","timestamp":1750632892000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Precise Real\u2010Time Measurement of Liquid Viscosity Using Digital Video Data"],"prefix":"10.1002","volume":"7","author":[{"given":"Zhiwen","family":"Pan","sequence":"first","affiliation":[{"name":"Otto Schott Institute of Materials Research Friedrich Schiller University Jena  Lessingstrasse 12\u201014 07743 Jena Germany"}]},{"given":"Tina","family":"Waurischk","sequence":"additional","affiliation":[{"name":"Federal Institute for Materials Research and Testing \u2013 BAM  Richard\u2010Willst\u00e4tter\u2010Str. 11 12489 Berlin Germany"}]},{"given":"Alexis","family":"Duval","sequence":"additional","affiliation":[{"name":"Otto Schott Institute of Materials Research Friedrich Schiller University Jena  Lessingstrasse 12\u201014 07743 Jena Germany"}]},{"given":"Ralf","family":"M\u00fcller","sequence":"additional","affiliation":[{"name":"Federal Institute for Materials Research and Testing \u2013 BAM  Richard\u2010Willst\u00e4tter\u2010Str. 11 12489 Berlin Germany"},{"name":"Institute of Non\u2010Metallic Materials Clausthal University of Technology  Zehntnerstr. 2a 38678 Clausthal\u2010Zellerfeld Germany"}]},{"given":"Joachim","family":"Deubener","sequence":"additional","affiliation":[{"name":"Institute of Non\u2010Metallic Materials Clausthal University of Technology  Zehntnerstr. 2a 38678 Clausthal\u2010Zellerfeld Germany"}]},{"given":"N.
