About Vid Extender

Vid Extender is an AI video platform for creators and marketers who want to turn a written prompt or an uploaded photo into a finished clip. Users describe the scene they have in mind, or start from an image, and the service generates a video using models such as Sora, Kling, Veo and Seedance.

Its main differentiator is video extension. A clip can be continued with a follow-up prompt, adding new scenes while keeping the visuals and story consistent, with the site stating that total length can reach up to five minutes. The workflow is three steps: upload a photo, enter a prompt describing what happens next, then choose a duration and generate.

Output can be set to landscape, portrait or square aspect ratios, which suits YouTube, TikTok and Instagram. The site also points to an API, tutorials, a knowledge base and a community for people who want to build on the platform or learn how to get better results.
