How to publish an AI story to YouTube, TikTok, and Instagram

Why publish from Scenette?

Most AI video tools stop at download. Scenette goes further: once your story is exported as an MP4, you can publish directly to YouTube, TikTok, Instagram, or Facebook from the same dashboard — no re-uploading, no switching tabs.

This guide walks through the full flow: create a story in the right format, export it, connect your accounts once, then publish (or schedule) to every platform you care about.

New to Scenette? Start with our first-story tutorial first, then come back here.

Step 1 — Pick the right format before you generate

Format matters for social. Choose it when you create your story:

• 9:16 portrait — TikTok, Instagram Reels, YouTube Shorts, Facebook Reels
• 16:9 landscape — YouTube long-form, Facebook feed videos, presentations

You can always export a ZIP of raw scene images and clips, but the assembled MP4 is what Scenette publishes to social. Portrait stories tend to perform best on TikTok and Reels; landscape works well for YouTube explainers and history-style content.

Step 2 — Build and polish your story

Before you publish, make sure the story is actually ready for an audience:

• Script & scenes — edit any scene prompt, then regenerate images until each frame looks right
• Transitions — optional animated clips between scenes for a cinematic feel
• Narration — add AI voiceover in your chosen language; tweak pacing if a scene runs long
• Captions — auto-generated captions help retention on muted autoplay feeds (TikTok, Reels)
• Music — background music with volume control in export settings

Browse the Showcase if you want inspiration for topics and visual styles that already work on the platform.

Step 3 — Export your final MP4

In the Story Creator, open the export panel and assemble your final video. Scenette stitches scenes, transitions, narration, captions, and music into a single MP4 file stored in your account.

Wait until the export finishes before publishing — the publish buttons use this finished file. If you edit scenes or narration after exporting, re-export so the published video matches your latest version.

You can also download a ZIP of all assets if you want a backup or plan to edit elsewhere. For social publishing inside Scenette, the MP4 export is what matters.

Step 4 — Connect your social accounts (one-time setup)

Go to Account → Connected accounts and connect each platform you want to publish to:

• YouTube — Google OAuth; grants upload access to your channel
• TikTok — TikTok OAuth; required for direct posting
• Instagram — connected via Meta; needs an Instagram Business or Creator account linked to a Facebook Page
• Facebook — Meta OAuth for Page publishing

You only do this once per platform. If a connection breaks (expired token, password change), Account will show a reconnect prompt — fix it there before retrying a publish.

Step 5 — Publish from the Story Creator

Once your MP4 export is ready and accounts are connected, use the publish actions in the final video panel:

Single-platform publish

Click the button for YouTube, TikTok, Instagram, or Facebook. A modal opens with platform-specific fields:

• YouTube — title, description, tags, and a scheduled publish time (15-minute slots). New uploads start as private on YouTube so you can review before going public.
• TikTok — caption (hashtags help discovery) and privacy level (private while testing, public when ready)
• Instagram & Facebook — title, caption, and optional schedule for later

Multi-platform publish

Publishing the same story everywhere? Use the multi-platform flow to compose once and queue uploads to every connected account in a single session. Scenette can suggest title and caption ideas from your story topic and scene titles — edit them before you send.

Uploads run in the background on our servers. You will see success or error feedback in the app; check Account → Published videos if something fails (expired credentials are the most common cause).

Platform tips that actually matter

YouTube

Use a clear title with your topic keyword (“The Fall of Rome — AI History Story”). Write a 2–3 sentence description with context and a link to Scenette if you want. Add 5–10 relevant tags. Schedule ahead if you batch content on weekends.

TikTok & Reels

Hook in the first second — your opening scene image matters more than the title. Keep captions short, front-load hashtags (#history #aistory #learnontiktok). Portrait 9:16 is non-negotiable. Post privately first to check audio levels and caption timing on a real phone.

Instagram

Reels favor the same vertical format as TikTok. Use the caption for context the video does not spell out. Instagram publishing requires a Business/Creator account — personal accounts cannot use the API.

Troubleshooting

• “Needs reconnect” on Account — disconnect and reconnect the platform, then retry
• Publish queued but nothing appears — check Account → Published videos for error details; uploads can take a few minutes
• YouTube video is private — intentional default; change visibility in YouTube Studio when you are happy with it
• Wrong aspect ratio — recreate the story in 9:16 or 16:9; cropping after export rarely looks good
