A computer implemented method for algorithmically editing digital video content is disclosed. A video file containing source video is processed to extract metadata. Label taxonomies are applied to extracted metadata. The labelled metadata is processed to identify higher-level labels. Identified higher-level labels are stored as additional metadata associated with the video file. A clip generating algorithm applies the stored metadata for selectively editing the source video to generate a plurality of different candidate video clips. Responsive to determining a clip presentation trigger on a viewer device, a clip selection algorithm is implemented that applies engagement data and metadata for the candidate video clips to select one of the stored candidate video clips. The engagement data is representative of one or more engagement metrics recorded for at least one of the stored candidate video clips. The selected video clip is presented to one or more viewers via corresponding viewer devices.
