Dynamical masses of star clusters are important constraints on the slope or lower-mass cut-off of the stellar IMF. The measurements of dynamical masses rest on model-based relationships between mass, line-of-sight velocity dispersion and projected half-light radius. We have used dynamical models that account for stellar evolution to compute the evolution of this relationship, depending on the wavelengths at which radii and velocity dispersions are observed. The conversion factor varies significantly over a few × 107 yr. In reddened starburst clusters that are observed at near-IR wavelengths, red supergiants are the dominant sources of light. We report on progress in the synthesis of stellar populations with strong red supergiant contributions. These stars are initially among the most massive stars, but they lose mass rapidly and the resulting dynamical evolution is complex.
