Introducing Filmora AI Extend: Expand Beyond Imagination

Filmora’s new AI Extend feature offers professional-grade video extension, delivering smooth continuity and stable performance. It integrates deeply with the timeline workflow, letting users edit AI-generated clips just as easily as normal ones. The feature lets users add effects and transitions freely without importing or exporting hassles.

Covering the entire creative process from AI asset generation to final editing and splicing, AI Extend seamlessly merges extended clips with originals, preserving story integrity and preventing jump cuts. Its intuitive interface enables one-click extension and clearly shows extension direction. The tool boosts efficiency by allowing quick addition of 5-10 seconds. Besides video extension, users also get the ability to extend the audio using AI.
