How content creators use Cutlin
Pick the kind of video
Text-to-video, a video from your photos, or Change the video for a clip you filmed.
Choose a style
Cutlin picks the model, such as Kling, Gemini Omni or one on Higgsfield, from those ticked in Settings. Pick a style for what the video is for, or leave it on Auto so your prompt decides the look. Then set the length and shape.
Download and cut it in
Download the clip and drop it into your edit in the editor you already use.
Video first
Videos run up to 30 seconds with Kling 4.0, in 16:9, 9:16, 1:1 or 21:9, and up to 15 with Gemini Omni 1.2, in 16:9 or 9:16. Each shape is labelled with where it is used, and Generate for social media remakes a finished video at exactly 1080 × 1920, with words and faces kept clear of the app's buttons. Change the video takes your own MP4 or MOV, up to 100 MB and 30 seconds, and changes it from a prompt while keeping its length and shape.
A brand sponsors can work with
Put your logo, colours, fonts and a few lines about you and your audience in Melon Cut Guidelines. Sponsors and editors take the right files from your link, and your own posts in Cutlin follow the same look when you name your @username.

Do I have to label AI videos?

A brand used in Cutlin is kept in Melon Cut Guidelines: its guidelines page is at meloncut.com/yourbrand, and Cutlin reads it from there.

- Video How long can AI videos be? AI video models generate short clips, from a few seconds to about half a minute at a time. In Cutlin, Kling 4.0 makes 3 to 30 seconds and Gemini Omni 1.2 makes 3 to 15. For a longer video, join several clips in a video editor.
- Video Can AI edit an existing video? Yes. Video-to-video AI takes a clip you already have and changes it from a description - a new style, a different setting, a changed detail - while following the original's movement. In Cutlin, attach an MP4 or MOV of up to 100 MB and 30 seconds and use Change the video; the result keeps the source's length and shape.
- Using AI content Do I need to label AI-generated content on social media? Sometimes. Platforms such as Instagram, Facebook and TikTok have their own rules for labelling AI-generated content, especially realistic images, video or audio that people could mistake for real people or events. The rules differ by platform and by country and change often, so check each platform's current policy and local law before you post. When in doubt, label it.
