We proposed a technique for observing ultrashort light pulse propagation in a microscopic space by using light-in-flight recording by holography. The technique introduces a microscope between the object and the holographic plate in the optical system of light-in-flight recording by holography, and can record and reconstruct a moving picture of magnified images of ultrashort light pulse propagation. A model of the microscope and a scheme of numerical simulation are established. The simulation uses ray tracing that considers coherence length. A microscope based on the technique was simulated. A microscope objective with a $10\times$ magnification was used in the simulation. It was verified that moving picture of a $10\times$-magnified image of a 130 fs light pulse propagation can be recorded for 4 ps.
