  X-ray multi-projection imaging (XMPI) provides rotation-free 3D movies of
optically opaque samples. The absence of rotation enables superior imaging
speed and preserves fragile sample dynamics by avoiding the shear forces
introduced by conventional rotary tomography. Here, we present our XMPI
observations at the ID19 beamline (ESRF, France) of 3D dynamics in melted
aluminum with 1000 frames per second and 8 $\mu$m resolution per projection
using the full dynamical range of our detectors. Since XMPI is a method under
development, we also provide different tests for the instrumentation of up to
3000 frames per second. As the flux of X-ray sources grows globally, XMPI is a
promising technique for current and future X-ray imaging instruments.
