Spatiotemporally resolved experimental vector magnetometry is combined with time-domain numerical micromagnetic simulation to investigate two, precessional-based, dynamic processes in thin-film magnetic elements. Large angle (>180^∘{}), ultrafast, magnetization vector motions compare well between experiment and simulation and constitute a direct observation of nearly-ideal precessional switching. High-frequency spin-wave generation is inferred by apparent reduction in the magnetization vector length. Small angle (1^∘{}) nonequilibrium modal oscillations in ferromagnetic resonance are compared and show considerable agreement in the long-wavelength magnetic spatial structure.
