Clip lengths, and what to do when you need more.
Lengths in Cutlin
You choose the length: up to 30 seconds with Kling 4.0 and up to 15 with Gemini Omni 1.2, or 10 with an opening and a closing frame. For social media, around 10 seconds is long enough for a hook and a message.
Shorter often works better
Short vertical videos are watched while scrolling, so a clear message in the first seconds matters more than length. Make the length fit the idea, not the maximum.
Length and credits
A video uses 60 credits for every started 5 seconds, so longer clips use more credits. The studio shows the cost before it makes anything.
