What is AI Video Extender?
AI Video Extender is an online tool that uses artificial intelligence to expand the duration of your videos. It predicts future frames and motion flow, creating extended clips that look authentic and coherent.
Who can benefit from using it?
It’s designed for creators, editors, marketers, and educators who need longer, smoother footage for storytelling, tutorials, ads, or background visuals — without reshooting or complex editing.
What distinguishes Voice Mode from Basic Mode?
Voice Mode extends both image and sound to maintain synchronization for talking or musical scenes. Basic Mode focuses purely on visual expansion, ideal for silent or loop-style videos. Voice Mode supports up to 1080p, and Basic Mode supports up to 720p.
How is credit usage calculated?
Credit cost is based on both resolution and selected mode: • Voice Mode: 480p = 20 credits/sec, 720p = 40 credits/sec, 1080p = 60 credits/sec. • Basic Mode: 480p 5s = 100 credits, 480p 8s = 150 credits, 720p 5s = 200 credits, 720p 8s = 300 credits. Credits are deducted automatically once processing begins.
How can I improve the output quality?
For the best results, upload clear, well-lit videos with stable motion and minimal compression. Shorter clips with consistent framing help the AI maintain smoother motion and more accurate scene continuation.
Can I use the generated videos outside this platform?
Yes. Once rendering is complete, you can download and use your extended videos anywhere — in video editors, social media posts, commercials, or personal projects, without any usage restrictions.
