Finds and fixes the continuity breaks in long AI videos. Made by one person who kept needing it.

Hour six of the same shot. This is the moment it was built for.

If you have ever made a long AI video, you know the feeling. You have been in it for hours, you have generated the same shot fourteen times, and you have stopped being able to see it. Then someone else watches it and says, so why does his jacket change colour halfway through.

A lot of that comes from how long AI video gets made. Video models top out at 15 to 30 seconds a go, so anything longer is a stack of short generations edited together. Each one is made from scratch and has never seen the others. Close enough in every piece turns into obviously wrong across twenty cuts, and that is when a video starts to look like AI.

That is what this is for, built to be the easiest way to deal with it. Our agent watches your whole video in one sitting and finds where things stop matching between shots and between generations. Clothes, faces, props, the light, the weather, where the furniture is, which way someone is facing. It marks those moments on the timeline, shows you the two frames that disagree, and writes down what to change in normal words.

Then it fixes them. Under every written fix is a Fix this shot button. One of the best frontier video editing models regenerates just that shot to match the frame where things were right, you look at a low-res draft first, and the fixed shot drops back into your video. You keep every shot that was already fine.

The finding is the part tired eyes are worst at. Our agent takes the first clear look at every person, prop and room as the reference, then holds every later shot up against it. Two reads run at once, one for the people and one for the room, with sharp stills from your original so it has clear frames to compare. Every shot gets written up, including everything that held.

Nobody has properly solved continuity for generated video yet. This is my go at finding the breaks and fixing them.

Who made it

I built this because I kept needing it. If it misses something, if a fix comes back wrong, or if you want it to catch something it does not, write to me. I read everything.
