About this paper
Zhixin Zeng, Jiahao Zhong
Cassette-Editor lets an agent revise existing video-editing projects by writing typed patches that the editor checks against project rules before committing them to the user’s editable history. In 31 requests, its full harness passed 89% of trials, versus 47% with basic tools. This one-model, one-turn evaluation measured valid, request-matching timeline documents, not film quality or user intent.
