MARGARIDA CARTAXO 

(she/her)

Assistant Editor

Margarida has always been captivated by the power of narrative. From a childhood immersed in theatre and role-playing games to her formal training at the Lisbon Theatre and Film School, storytelling has driven her life. In 2013, she graduated with a BA in Film Editing, falling in love with the craft whilst cutting the documentary Almas Censuradas—a project that revealed the profound impact an editor has in shaping, enhancing, and adding complex emotional layers to a story.

She relocated to London in 2017, landing her first UK role as a freelance Assistant Editor on the BBC’s long-running medical drama Holby City. To deepen her technical expertise, she joined Argonon Post as a Junior Edit Assistant, earning a promotion to Edit Assistant within seven months and gaining a comprehensive understanding of Avid Media Composer and the post-production workflow.

A major milestone came in 2021 when Margarida was selected for the inaugural Grierson Trust DocLab In Focus: Editing scheme. Mentored by editor Joby Gee, this opportunity led to a nine-month Netflix placement as an Assistant Editor on Running with the Devil. Since then, she has worked as both an Assistant Editor and Editor across various projects.

Her first Editor credit was on the documentary Made in England: The Films of Powell and Pressburger, which premiered at Berlinale 2024. Collaborating with the legendary Thelma Schoonmaker stands as her proudest and dearest professional achievement to date.
