要点
What matters
Adobe 9 月 8 日介绍 Premiere 的 Generative Media Tool，可在时间线上生成视频和音效，并选择 Firefly 或合作模型。After Effects 的 AI Assistant 进入公开测试，支持项目整理与多步骤操作。
Adobe’s September 8 update introduces timeline video and sound generation in Premiere, with Firefly and partner-model choices. After Effects gains an AI Assistant in public beta for project organization and multi-step tasks.
范围与限制
Scope and limits
声音部分包括串音分离、分层音频控制和自动压低背景声；新 AI 音频工具属于公测。Soundscape 与 Music 也标有 beta，不能笼统称作全套正式版功能。
Public-beta audio tools include crosstalk separation, layer controls and automatic ducking. Soundscape and Music also carry beta labels; these features should not be presented as uniformly production-released.
编辑观察：如何用到工作中
Editorial note: putting it to work
先复制一份短片工程，分别测试补镜头、访谈串音和 AE 图层整理。验收是否保留可编辑结构、是否能撤回，以及原项目能否继续由同事接手。
Use a duplicate project to test missing shots, overlapping speech and AE layer organization. Check editability, reversibility and handoff to another editor.
