Series Automation

Creating a consistent content flow can be overwhelming, but with ShortsNinja Series Automation, your Shorts schedule runs like a machine. Here’s how we take care of it behind the scenes so you can stay creative while we stay on time.

Rules - How ShortsNinja Does It

A Series lets you schedule and automate multiple Shorts in a themed sequence — perfect for building a content pipeline like "AI Tips of the Week" or "Top 10 Unsolved Mysteries."

How To Create A Series

Want to update voice, visuals, or schedule for an existing series? You can easily edit any series you've created. You can also enable/disable or delete it entirely.

How to Edit a Series

Managing your automated video series in ShortsNinja doesn’t mean giving up control — quite the opposite. You can edit, override, or even regenerate upcoming videos whenever needed. Here’s what you can do to stay fully in command.

Controlling the Series

Video Editor

The ShortsNinja Video Editor gives you full creative control over how your AI-generated short is structured, styled, and finalized. Whether you’re fine-tuning voiceover timing, adjusting visuals, or preparing your thumbnail — everything happens here.

Overview

The Global Scene tab allows you to define assets and audio that should apply across the entire video, rather than per-scene. Think of it as your “global layer” — anything here will overlay or blend into all scenes in the final render.

Global Scene

The Thumbnail tab allows you to add a short, engaging intro at the very start of your video — perfect for grabbing attention on platforms like TikTok or YouTube Shorts.


Thumbnail

Scenes are the core building blocks of your video. Each scene contains a group of scene items — such as voiceovers, visual assets, and music — that play together for a specific duration. You can rearrange, customize, and extend them however you'd like.



Scenes

Scene Items

Each scene is made up of scene items — individual components like voiceovers, visuals, or music — and every item gives you precise control over how it behaves within the scene.

Scene Item Controls

Voiceovers are at the heart of AI-generated Shorts — they drive the message, pacing, and tone of each scene. In the video editor, the Voiceover scene item gives you full control over the text, voice, and timing.

Voiceover Scene Item

Assets are the visual building blocks of your scenes — images, videos, AI content, and uploads — and each one is fully customizable in both appearance and behavior.

Assets Scene Item

Audio scene items let you add music or sound effects to individual scenes. You can fine-tune the track’s behavior, speed, and looping to perfectly match the pacing and tone of your story.


Audio Scene Item

Captions are small animated words or phrases that appear directly on your video in sync with your voiceover. They’re designed to add energy, improve retention, and boost accessibility — especially on platforms like TikTok and Instagram.

Captions

The Voiceover tab lets you choose the default AI voice that will be used across your entire video. Once applied, this voice will regenerate all scene voiceovers and subtitles to match the selected voice style.

Voiceover

The Metadata tab is where you define your video’s title, description, and hashtags — all optimized for publishing on platforms like TikTok, YouTube Shorts, or Instagram Reels.

Metadata

The Jobs tab shows you a real-time status of all background AI processes running for your video — such as voiceover generation, AI image creation, subtitles, or video rendering.

Export/Publish Video

The Export / Share section is where you render, download, and publish your finished video directly to social platforms like TikTok and YouTube Shorts.
