Runway Edit Studio 30 s edits vs Sume's Omni edit

Runway's Aleph 2.0, launched May 21, 2026 inside Edit Studio, edits clips up to 30 seconds at 1080p in a web interface. Sume offers prompt-based video editing through the API with gemini-omni-flash-1.1, which takes a video_url and a prompt that describes the change.

What Runway announced

According to Runway's announcement, Aleph 2.0 edits up to 30 s at 1080p, lets you show a frame of the desired edit, supports multi-shot edits across cuts, and is available on all paid plans on desktop web.

How Sume's edit mode works

In the Video Router catalog, gemini-omni-flash-1.1 routes by request shape. Sending video_url selects video_to_video: the prompt describes the edit, resolution is optional with a 720p default, and aspect_ratio and duration are not sent. The model is documented at 3 to 10 seconds across 360p to 4K.

The docs do not publish a separate length cap for the edit source, so test your clip length before you plan a workflow around it. video_url is the edit source, not a reference, and cannot be combined with image_url, end_image_url or any reference_*_urls. Native audio is always on, and billing is the provider list price times 1.25 per output second by resolution.

Which one to pick

Pick Edit Studio when you want to work interactively on a long single clip and your plan covers it. Pick the API route when edits are part of a pipeline: you get an async job, an idempotency key and a result you can fetch from the job endpoints.

For clips longer than the model envelope, cut the source into pieces first. Sume documents a separate trim job for range cuts, and the edited pieces can be joined afterwards.
