Runway Aleph 2.0 Editing Model Adapts Videos to Any Format

Runway Aleph 2.0 编辑模型：一键适配任意视频格式

Runway introduced the Aleph 2.0 video editing model, letting users upload an existing video in its desktop web app, choose an aspect ratio, and have the model fill the remaining scene area for the selected format.

Why it matters: Runway Aleph 2.0 is a mid-weight video product update with a concrete mechanism, but no pricing, quality evals, or rollout scope. HKR-H/K/R pass, placing it at the low featured threshold.
