Thumbnail Automation

Eye-catching thumbnails. Generated for every single clip.

Longwave creates a custom thumbnail for each clip - choosing a mood-matched background, overlaying a CTR-optimized title, and rendering it ready for YouTube and X. No Canva, no Photoshop, no time wasted.

Ce que vous obtenez

What makes Longwave thumbnails different

Mood-matched backgrounds

Six mood categories - urgency, curiosity, authority, shock, question, listicle - are matched to each clip's emotional tone. The right background doubles CTR.

AI-generated thumb titles

A separate AI prompt generates a 3 - 6 word ALL-CAPS title optimized for thumbnail readability - deliberately different from the video title, designed to tease and intrigue.

Impact font with bold outline

White Impact text with a 10px black stroke is readable on any background at any screen size - the same technique used by every top-performing Shorts creator.

Platform-specific dimensions

YouTube Shorts thumbnails are 1080×1920. X thumbnails are also generated at the correct aspect ratio. Both are rendered and uploaded automatically.

Custom template library

Upload your own branded background templates in the Thumbnail Designer. Your brand, your colors, your style - AI handles the text overlay.

Zero designer required

The full pipeline - mood detection, template selection, title overlay, upload to YouTube - runs automatically for every clip you generate.

Comment cela fonctionne-t-il ?

From clip to published thumbnail

01

Mood & title detection

The AI analyzes the clip's transcript to assign a hook_type (one of 6 moods) and generate a thumb_title - 3 - 6 words in ALL CAPS designed to maximise curiosity and CTR.

hook_type: curiosity | thumb_title: WHY EXPERTS WERE WRONG
02

Template selection & render

A background template tagged with the matching mood is chosen from your library. The thumb_title is overlaid in Impact font at the vertical center of the frame. The final PNG is saved locally on the worker.

Thumbnail rendered: 1080×1920
03

Upload to platform

For YouTube: the thumbnail is uploaded via the YouTube Data API after the video is published. For X: the thumbnail is burned in as a 1-second first frame (X has no custom thumbnail API).
