  In the past years, we have undertaken an extensive investigation of LMC and
SMC star clusters based on HST data. We present photometry and astrometry of
stars in 101 fields observed with the WFC/ACS, UVIS/WFC3 and NIR/WFC3 cameras.
These fields comprise 113 star clusters. We provide differential-reddening maps
and illustrate various scientific outcomes that arise from the early inspection
of the photometric catalogs. In particular, we provide new insights on the
extended main-sequence turn-off (eMSTO) phenomenon: i) We detected eMSTOs in
two clusters, KMHK361 and NGC265, which had no previous evidence of multiple
populations. This finding corroborates the conclusion that the eMSTO is a
widespread phenomenon among clusters younger than ~2 Gyr. ii) The homogeneous
color-magnitude diagrams (CMDs) of 19 LMC clusters reveal that the distribution
of stars along the eMSTO depends on cluster age. iii) We discovered a new
feature along the eMSTO of NGC1783, which consists of a distinct group of stars
going on the red side of the eMSTO in CMDs composed of ultraviolet filters.
Furthermore, we derived the proper motions of stars in the fields of view of
clusters with multi-epoch images. Proper motions allowed us to separate the
bulk of bright field stars from cluster members and investigate the internal
kinematics of stellar populations in various LMC and SMC fields. As an example,
we analyze the field around NGC346 to disentangle the motions of its stellar
populations, including NGC364 and BS90, young and pre-MS stars in the
star-forming region associated with NGC346, and young and old field stellar
populations of the SMC. Based on these results and the fields around five
additional clusters, we find that young SMC stars exhibit elongated
proper-motion distributions that point toward the LMC, thus bringing new
evidence for a kinematic connection between the LMC and SMC.
