Runway Aleph

You give Runway Aleph a clip and a plain-language instruction, and you get back an edited or restyled video, usually in 30 to 60 seconds.

Runway Aleph is a free AI video editor that handles style transfer, object removal and video-to-video changes in one model, and it tries to keep the rest of the scene intact while changing only what you ask for.

There is no login or account needed on the free tier.

Generated videos can be used commercially, and the service says data is never stored and nothing is tracked.

The catch is quality.

Output is capped at 360p for now, with HD listed as coming soon.

Clips run 5 to 30 seconds, sound effects are basic, and processing is at standard speed.

A Pro plan adds priority processing.

For quick social clips, short ads or testing an idea, the free access is the main draw.

If you need finished HD work, the resolution cap will matter.
