About AI Video Extender
AI Video Extender is an online tool that generates new footage to extend videos either before or after an existing clip while preserving the original scene as visual context. Users upload a video in MP4, MOV, or WebM format up to 100 MB and choose between 5-second or 10-second extensions at 768p or 2K resolution. The tool supports multiple aspect ratios including 16:9 landscape, 9:16 portrait, and 1:1 square. Users provide a prompt describing the desired action or visual moment for the generated footage, which the AI uses alongside the source video’s context to create coherent extensions. This approach is useful for adding new footage to short videos without resorting to looping, slow motion, or freeze frames. The workflow is browser-based, eliminating the need for manual editing timelines. It is designed for extending various types of videos including social media content, product videos, cinematic scenes, marketing campaigns, and B-roll footage.
