It is a tool that uses artificial intelligence to extend video duration. It works in two main ways: first is "continuation," generating brand new video frames to continue the story; second is "frame interpolation," inserting new frames between existing frames to create smooth slow motion.

AI makes the most logical inferences based on existing information in the video (such as object motion direction and speed). It excels at handling videos with clear motion trajectories and relatively stable scenes. For complex plot twists, it will do its best to create a natural and smooth continuation.

A world of difference! Regular slow motion just extends the playback time of each frame, causing severe stuttering when frame rates are insufficient. "Smart Slow Motion" uses AI to generate brand new intermediate frames that originally didn't exist, filling the gaps in the footage, thus creating incredibly smooth, professional-grade slow motion effects without stuttering.

Typically "AI Continuation" provides fixed extension duration options (such as +2 seconds, +4 seconds), while "Smart Slow Motion" depends on your chosen multiplier (such as 2x, 4x, 8x). We provide optimal options based on technical capabilities.

Absolutely safe. Your privacy is our highest priority. All uploaded videos are encrypted and only used for the current extension task. We will never store or share any of your files.
