Sand.ai

Unlimited video continuation is the feature that sets Sand.ai apart: you can keep extending a clip instead of stopping at a fixed length.

Sand.ai is an AI research company and video generator whose model, Magi-1, creates new video and extends existing footage.

The listing for Sand.ai also covers an AI API and open source AI models, so developers can work with it as well as people who just want to make clips.

Sand.ai offers precise control over how a video is generated, and generation times are fast.

Output quality is a selling point too.

You need an account and a login before you can use Magi.

Since the system leans on AI, some users may find they have less hands-on creative control than in a traditional editor.

Sand.ai suits experiments with long, continuous clips and developers who want to build on an open video model.
