23. Destination

Export, schedule, or publish your video directly to social platforms from Mosaic.

The Destination tile lets you export, schedule, or publish your video directly to social platforms from Mosaic — no need to download and re-upload manually.

How It Works

Add the Destination tile at the end of your workflow. When it runs, Mosaic formats your video for the target platform(s), optionally generates social captions, and publishes or exports.

Input & Options

Publishing Mode

Mode	What it does
Review before publishing	Preview and approve posts before they go live
Publish immediately	Posts go out as soon as they're ready
Export only	Skip platform publishing — just download the file

Publishing Platforms

Connect and publish to:

• X (Twitter)
• LinkedIn
• Instagram
• Facebook
• TikTok
• YouTube

Click Manage Social Media Integrations to connect, disconnect, or refresh your accounts. You only need to do this once per account.

AI Captions for Posts (Optional)

Tell the AI how to write your social media post text.

Examples:

• "Make it witty and add relevant hashtags"
• "Write for LinkedIn with a strong hook and CTA"
• "Write for TikTok using casual language and emojis"

Leave empty for a neutral auto-generated caption.

TIP

Destination works best at the end of a workflow chain like: Clips → Reframe → Captions → Destination

API Info

Node Params & API Details

• Node ID: e840b66c-488c-4247-9e46-756b914fc287

Node params

Param	Type	Required	Default	Notes
platforms	("x" | "linkedin" | "instagram" | "facebook" | "tiktok" | "youtube")[]	Yes	[]	At least one platform required.
approval_mode	"manual" | "auto"	No	"manual"	Manual review queue vs immediate publishing.
ai_instructions	string	No	""	Prompt for social caption generation style/tone.

Parameter groups

• Destination routing (required): platforms
• Publish policy: approval_mode
• Caption generation guidance: ai_instructions

Scenario requirements

• platforms must be non-empty.

Runtime notes

• Backend resolves caption instruction text from multiple keys (ai_instructions, ai_prompt, instructions, prompt) for backward compatibility.
• Only connected social accounts are selectable in UI, but API clients can still submit valid platform IDs directly.

Example

{
  "platforms": ["linkedin", "youtube"],
  "approval_mode": "manual",
  "ai_instructions": "Write concise posts with a hook and one CTA."
}
