About this tool
Video Extend es la herramienta del generador de video con IA de ClipTrend para alargar video con IA — sube un clip corto y un prompt de continuación, y Kling Extend Beta genera los siguientes segundos manteniendo movimiento, luz y la identidad del sujeto del clip original. Útil para estirar clips cortos hasta la duración de TikTok / Reels o para añadir un beat de historia planeado. MP4 sin marca de agua, derechos comerciales completos.

Kling Extend Beta is the platform's most reliable ai video extender — a continuation edit model with end-frame guidance that works on any uploaded clip, regardless of which model generated the original. It analyses the final frames of your source video, preserves character identity and scene composition, and generates the next 5-10 seconds of motion with matching lighting. Kling Extend Beta accepts prompts up to 2000 characters, so you can.
Seedance 2 extend is the premium option for continuing Seedance-origin clips using the model's omni-reference capability. Because Seedance 2 accepts the original clip as a reference video along with additional image and audio references, the continuation preserves character, scene, and motion style far better than a pure video-to-video extend. Use this path when your source clip was generated by Seedance 2 or Seedance 2 Fast and you need a 4-15.
Wan 2.7 extend uses first-and-last frame conditioning to create frame-consistent extensions — particularly useful when you need to create a seamless loop (where the final frame matches the first) or extend a clip to land on a specific composition. The model reads the target end frame as a constraint, so you can precisely control where the extended clip finishes. Ideal for social backgrounds, NFT drops, brand loops, and scenes that.
Kling 2.5 Turbo extend is a cheaper alternative to Kling Extend Beta when you need fast iteration — 26 credits per pass, 5 or 10 second continuation output. Quality trails the Kling Extend Beta flagship for complex scenes but is perfectly serviceable for short creator content, talking-head continuations, and simple product clips. The speed-and-cost advantage makes it the right pick for running multiple continuation variants before locking the final.
Compare the supported models across the dimensions that matter most for AI video and image generation: duration, resolution, audio support, creative flexibility, and cost.

Upload your clip to the Video Extend page, describe what should happen next in the prompt box, pick Kling Extend Beta (the most reliable AI video extender option), and click Generate. The ai video extender produces the next 5-10 seconds in about 60-90 seconds on the AI video extender with pay-as-you-go credit packs.
ClipTrend ships Kling Extend Beta (the default video extender ai for any uploaded clip), Seedance 2 extend (purpose-built for Seedance-origin sources via omni-reference), Wan 2.7 extend (first-and-last frame control for loops and precise transitions), and Kling 2.5 Turbo extend (the cheapest option for rapid iteration).
Yes — generate a 10-second continuation with Kling Extend, then re-upload the joined clip and run a second extend pass on the ai video extender to reach 15-20 seconds. Each pass preserves motion continuity because the model reads the final frames of your current clip as the starting point.
Yes. ClipTrend is an AI video extender with pay-as-you-go credit packs from $11.99 and every MP4 export is watermark-free on every tier. Kling Extend Beta uses 21 credits per pass, so a Starter pack of 500 credits for $11.99 comfortably covers several extensions. No forced signup chain, no waitlist, no "upgrade to remove watermark" gate.
Pick Kling Extend Beta on the Video Extend page — this is the Kling AI extend video workflow built into ClipTrend. Upload your source clip, add an optional end-frame reference image if you want tight compositional control, write a continuation prompt (up to 2000 characters), and click Generate. The Kling AI extend video pipeline output duration follows the source video — so a 5-second source produces a 5-second continuation, and you can stack Kling AI extend video passes to reach the target AI extend video length.
Yes. Kling Extend Beta is source-agnostic — it works on any MP4 at 3-10 seconds, regardless of which AI tool generated the original. Runway, Pika, Luma, and raw phone clips all extend cleanly. This is the biggest practical advantage over single-vendor extend tools, which usually only work on clips generated inside their own ecosystem.
You do not need Premiere, DaVinci, or After Effects — our AI video extender handles everything in a single browser tab. Upload the source clip, write a short continuation prompt, click Generate, and the video extender ai produces the next segment in 60-120 seconds. Stack extend passes to reach 20-30+ seconds for the best Shorts and Reels retention.
Kling 2.5 Turbo extend at 26 credits per pass is the cheapest ai extend video on the platform, which makes it the right pick for rapid iteration. For final-grade output, upgrade to Kling Extend Beta (21 credits). Seedance 2 extend and Wan 2.7 extend suit specific workflows (Seedance-origin clips and first-and-last-frame loops respectively).
El consumo real depende del modelo. Las generaciones de entrada cuestan aprox. 21 créditos. Paquete Starter desde $11.99, sin suscripción obligatoria, reembolso automático si falla.
