Videos of single crystals tracked by the slug triggering mechanism comprising an optical trigger and translation of the motorised stage to artificially suspend the single crystal in the X-ray beam during data collection. Videos are categorised into unseeded and seeded crystallisations of paracetamol (PCM). The unseeded cooling crystallisation are further segmented into 6.7 m and 8.7 m crystalliser length. N.B videos are rotated by 180° and thus is observed as residing in the top of solution slug
