  • Abstract
    Eulerian video magnification is a video processing technique for amplifying subtle temporal oscillations in video footage. Applying this technique to footage of an H-mode plasma shot on the mega-ampere spherical tokamak, a global magnetohydrodynamic mode is amplified, and its spatial structure is made readily visible. This technique has broad applicability across plasma physics.
