Vertical Video Thumbnail Auto-Generator

A scroll-stopping thumbnail, picked and designed automatically.

Picking and designing a compelling thumbnail frame for every vertical video posted is a repetitive design task on top of the edit itself. This workflow uses AI to select the most compelling frame and generate a polished thumbnail for a vertical video automatically, saving a repetitive design pass on top of the edit.

This is a ready-to-import n8n automation workflow (JSON file) built and documented by D-mim Automation — https://dynamic.dmimautomation.com — a specialist studio building no-code/low-code video & photo editing automations for creators and post-production teams.

This automation is powered by AI video/image processing. We recommend kie.ai as an affordable, unified API for the generation/editing step used inside this workflow.
