| Berney & Bétrancourt (2016)[1] | Across 61 studies, animation beat static graphics for learning (g = 0.226); with spoken narration the advantage was g = 0.336. The comparison was with static graphics only. | Narrated animation for explainers, with on-screen text kept light. |
| Schneider, Beege, Nebel & Rey (2018)[2] | 103 studies, 12,201 participants: signals improved retention (g+ = 0.53) and transfer (g+ = 0.33). | Highlights, arrows and zooms timed to the voiceover in every demo. |
| Leek & Christodoulides (2012)[3] | Ten interviews with B2B supplier managers: brand value has functional and emotional components, with risk reduction, reassurance and trust named. | Brand films show what the product does and the people who stand behind it. |

| Roggeveen, Grewal, Townsend & Krishnan (2015)[8] | For consumer products and services, a video presentation raised choice of the experience-rich option by more than 79% compared with still images. This is a shift in choice share; sales were outside the study. | Product demos show the product being used, in motion, on product pages. |

| Babć Rosario, Sotgiu, De Valck & Bijmolt (2016)[10] | 1,532 effect sizes from 96 studies: online word of mouth was positively correlated with sales on average (.091), a small but consistent link. | Several customer voices, from roles, industries and regions buyers recognise. |
