Part 1. 7 Game-Changing AI Video Extender Tools for Longer, Smoother Clips

If you are looking to increase the length of your videos to some extent, here are the 7 AI video extenders that won't disappoint you.

1. Runway ML

The Gen 3 Alpha Turbo and Gen 4 Turbo models of Runway ML create short videos that look close enough to real life, and each of them is also an amazing AI video extender tool.

Runway ML handles characters, objects, and backgrounds in a steady way so your scene does not fall during transitioning. You can control the camera movements and the vibe (bright or dark colors) with your text prompt. You also get 4K upgrades and video-to-video generation options, so your final video has everything you want in it.

Runway ML AI Video Extender Key Features

Adds more seconds to the clip you created inside Runway. It continues the scene by creating new frames that match the last part of your video. There is an option as well for you to choose if it follows your prompt or the last frame on its own.
Type a prompt that guides the added part so it moves in the direction you want. This stops the tool from repeating the same motion again and again.
Lets you add more time again and again until the clip reaches around forty seconds. The quality remains great, and the transitions are always smooth.
The tool joins the original part and the extended part very cleanly, so the motion remains natural from one part to the next. There is no sharp cut that distracts you.
