Read the vendor's own shutdown notice for dates, export every video and prompt before the cut-off, write down what the old tool did for you, and rebuild that workflow on a generator that covers the same jobs.
For anyone asking: What happened to Sora, and where do I move my AI video work now?
Each one's way of doing it, and the point where it stops.
Runway's Agent builds multi-shot videos from a request, choosing between Gen-4.5 and other labs' models such as Veo 3.1 and Kling in one workspace. Where it stops: Gen-4.5 makes 2 to 10 second clips at 720p with no sound of its own, in the web app only.
Type a scene or upload an image and Kling generates the clip with native audio; Kling 4.0 makes 3 to 30 second clips with multi-shot on by default. Where it stops: Basic is 720p with a watermark and no commercial use.
Cinema Studio 4.0 lets you direct clips up to 30 seconds with camera presets and Elements for characters, and Popcorn storyboards a sequence across many models in one account. Where it stops: Cinema Studio 4.0 blocks real faces; Free puts a watermark on every generation and excludes commercial use.
Scenes plans a storyboard of keyframes and renders nothing until you approve it, then Luma Agents generate with Ray3.2 or Kling, Seedance and Veo. Where it stops: Ray3.2 output is silent; there is no free plan and trial output is for internal evaluation only.
Agent Two turns a prompt or script into an edited video with voiceover, music and subtitles, and takes clips from other tools as MP4 files to cut and caption. Where it stops: Starter gets Agent Two Lite and only Seedance 2.0 Fast / Mini; timeline exports go up to 1080p MP4.
Omni Flash 1.2 and Veo 3.1 Lite make clips with sound from text or images, and Characters with @me puts your own avatar into a scene. Where it stops: Free use runs on a daily allowance and may be unavailable at peak hours; Veo 3.1 Fast, Veo 3.1 Quality and Omni Flash 1.1 retire in Flow on December 5, 2026.
For business explainers and training only: the AI Video Assistant or Syren turns a script or deck into an avatar-presenter video, not a free-form cinematic scene. Where it stops: Basic has no MP4 download.
