本研究从“剧目”概念和数字策展视角入手，揭示新冠肺炎疫情暴发初期若干短视频的生命轨迹，以此理解数字符像事件的生成和疫情及其记忆的展演。对多个案的比较分析发现，数字符像事件的生命历程涵盖流传、驯化和经典化三个阐释阶段。在每个阶段的多模态记忆实践中，社交媒体用户和机构媒体先后投入种种数字策展工作。这些工作制造出短视频副本或变体，续写或翻转表演的剧情，放大或改造表演者和观众的情感，并将之带入宏大叙事。最终，短视频或者稍纵即逝，或者刻入以“感动”为主调的公共记忆。

Drawing on the perspective of digital curation, this article analyzes the life trajectories of several short videos widely circulated during the Wuhan lockdown to explore the making of digital iconic events and the performing of COVID-19 and its memories. The comparative analysis of multiple cases reveals that the social life of digital iconic events covers three interpretive phases, i.e., circulation, domestication, and canonization. In their multi-modal memory practices, social media users and institutional media mobilize a wide variety of digital curation strategies to create copies or variants of the short videos, extend or reverse the performance scenarios, amplify or transform the emotions of performers and the audience, and integrate them into the grand narrative. Eventually, some short videos became fleeting moments, while others were etched into public memory with a “moving” tone.
