Video reverser andlooper
Play it backwards for the reveal-in-reverse trick, or loop it until it fills the duration you need. Both run on your own machine on files of any size.
How to use the video reverser in three steps
Reversal is a cheap trick that still works — the pour that un-pours, the jump that lands backwards, the boomerang. Looping is the quiet workhorse: a three-second background clip that has to sit under a ninety-second narration. Shorz does both as single-file operations that don't need a project.
Reverse it
Point Shorz at a clip and it writes a reversed copy. The original stays exactly where it was, so you can put the forward and backward versions next to each other.
Backwards, as a new file
Or loop it
Repeat a clip a set number of times, or tell Shorz the duration you need and let it work out how many loops that takes. Works on images treated as video too.
N loops, or a target length
Use it in the edit
A reversed or looped clip is just a file — bring it into a project as a scene, a background, or B-roll, and caption and score it with everything else.
Straight into a project
Find it in the app under MCP single-file tool.
Why Video Reverser in Shorz
Loop a background to fit the voiceover
A generated clip is a handful of seconds; narration is minutes. Looping to a target duration is what makes a short AI-generated shot usable as a full-length background — no manual copy-paste chain.
Pairs with AI video
Reverse-and-forward, from one prompt
Ask your AI assistant to reverse a clip and join it to the original and you have a seamless boomerang in one instruction — a reverse tool and a merge tool talking to each other.

Shorz speaks MCP
Shorz isn't a locked web app. Connect it to Claude, Cursor, Codex or Gemini and your assistant can drive it directly — one message instead of a panel full of clicks. You review before anything is published.

Video Reverser questions
The tool reverses the video. For clips where the audio matters, the usual workflow is to reverse the picture and lay a music track or narration over it in the project.
Yes. Give Shorz a target duration and it loops the clip until it reaches it, or give it a specific number of loops instead.
Yes — the loop tool treats an image as video, which is how you turn a single generated still into a background clip of any length.
Reverse and loop are single-file tools driven over MCP — ask the AI assistant you've connected to Shorz (Claude, Cursor, Codex or Gemini) and it runs them on your local files.
