  This paper presents the baseline method proposed for the Sports Video task
part of the MediaEval 2021 benchmark. This task proposes a stroke detection and
a stroke classification subtasks. This baseline addresses both subtasks. The
spatio-temporal CNN architecture and the training process of the model are
tailored according to the addressed subtask. The method has the purpose of
helping the participants to solve the task and is not meant to reach
stateof-the-art performance. Still, for the detection task, the baseline is
performing better than the other participants, which stresses the difficulty of
such a task.
