AI video generation has a length problem: the best takes are often short. You land a fantastic 5-second clip — the motion is right, the character is right, the lighting is right — but the ad slot needs fifteen seconds, and regenerating longer means rolling the dice on everything that already worked.
Extend Video solves it by continuing a clip from its ending. Layer generates new footage that picks up exactly where the original stops, with optional text direction for what happens next. Keep the take you love and grow it — into a longer ad, a narrative sequence, or a seamless loop.
Key Capabilities
Continue from the ending The extension starts from your clip's final moments, so motion, subject, and style flow through the cut. It reads as one continuous shot, not two clips stapled together.
Optional text direction Steer the continuation with a short prompt — the camera keeps pulling back, the character turns and smiles, the treasure chest bursts open. Leave it blank and the scene carries forward naturally.
Chain extensions for length Extend the extension. Build a 5-second winner into a 15- or 30-second cut beat by beat, keeping creative control at every step instead of betting one long generation.
Protect your best takes Great generations are hard-won. Extension means you never abandon a strong clip because it's too short — length becomes something you add, not something you gamble for.
Leading models, one workspace Extend clips generated with video models including Veo 3.1, Seedance, Kling, and Wan — all inside Layer's single workspace with 149+ AI models across image, video, 3D, and audio.
How It Works
Choose the clip Pick the generation you want to grow — the take where everything clicked.
Direct the continuation Optionally describe what should happen next. Your direction shapes the new footage while the clip's ending anchors continuity.
Extend and repeat Layer generates the continuation. Review it, extend again if you need more length, or send the result into the timeline editor for finishing.
Built for Game Production
Ad-length UA creatives Ad slots have minimum durations that short generations can't fill. Extend a proven 5-second hook into 15- and 30-second cuts that qualify for more placements — without losing the hook.
Narrative beats for trailers Grow a single strong shot into a sequence: the reveal continues into the reaction, the reaction into the payoff. Build trailer moments incrementally with control at each beat.
Loops for playables and social Extend a clip toward a natural loop point for ambient social posts, store page videos, and background motion that plays endlessly without a visible seam.
Live-ops content, stretched to fit Repurpose one hero generation across formats — a short teaser, a mid-length promo, a full announcement — by extending the same source to each length you need.
