1) The preliminary task had limitations like only using an iPad with iMovie and 30 minutes to plan, film and edit. This resulted in a lack of shot types and inability to control things like ISO and aperture.
2) For the final piece called "Unconscious", the filmmakers had access to DSLR cameras allowing close-up shots and control over settings. They also used professional editing software like Adobe Premiere Pro which allowed for precise editing.
3) Mise-en-scene aspects like props, costumes, makeup and setting were more developed for the final piece, using things like guns and an abandoned setting to add production value.
