LTX-2 is a new AI video model dropped in Oct 2025 by Lightricks and Retake is a tool built on top of LTX-2. It lets you take a finished video and tweak small parts like a line of dialogue, emotion, or camera angle... without starting over.
Basically, it's a video fixer. You can fix a scene or change the vibe without messing up the whole clip.
This saves a lot of time. Before this, you’d have to reshoot or regenerate everything if one moment didn’t land. Now you just change that one bit.
Retake keeps the rest of the video as-is. Lighting, sound, movement, everything around the edit stays untouched.
It’s handy for ad teams, creators, studios... anyone who needs quick edits without redoing it all.
You can change clips that are about 2 to 16 seconds long without touching the rest.
Lets you redo acting, lines, timing, emotion or camera moves while keeping the same setting and sound.
Everything else stays smooth... motion, light, and audio don't break.
What it’s good for:
Brands or agencies can swap out a line in a commercial without doing the whole thing again.
Filmmakers or creators can test out different takes without starting fresh.
Post production fixes are faster, like adjusting tone or fixing a wrong line.
Great for quick versions or testing stuff out for client feedback.
