Process description

This automation is a complete system for automatically creating viral clips from long videos. The system takes a link to the video via a web form, analyzes it using Vizard AI to identify the most viral fragments, generates attractive titles using AI, and automatically publishes ready-to-make clips to TikTok via the Blotato platform.

API keys and services:

1. Vizard AI API - for analyzing videos and creating clips
2. OpenAI API Key - for generating titles and descriptions (gpt-4o-mini)
3. Blotato API - for uploading media and publishing on social networks
4. TikTok Account ID - for automatic publishing

System architecture by blocks

SECTION 1: SENDING VIDEOS

1.1 On form submission - Getting a link to a video

Purpose: A web form for getting links to videos from users

Form settings:

• Form Title: “Clips”
• Form Fields: One “Link to video” field
• Webhook ID: 453572d2-e25b-48d5-bf2e-58a54b438a19

‍

Supported platforms:

• youtube
• Instagram
• TikTok
• Vimeo
• Other video platforms

1.2 HTTP Request — Sending to Vizard AI

Purpose: Creates a project in Vizard AI to analyze videos and generate clips

HTTP Request settings:

• Method: POST
• URL: https://elb-api.vizard.ai/hvizard-server-front/open-api/v1/project/create
• Authentication: HTTP Header Auth (Vizard AI credentials)
• Credentials: Vizard AI (Your Vizard AI API Key)

JSON Body:

{

“lang”: “en”,

“preferLength”: [0],

“videoURL”: “{{$json ['Video Link']}}”,

VideoType: 2,

“MaxClipNumber”: 8

}

‍

Request parameters:

• lang: “en” is the language of analysis
• PreferLength: [0] - preferred clip length (0 = automatic)
• VideoType: 2 - type of video for processing (In this case, we take video from YouTube)
• MaxClipNumber: 8 - maximum number of clips

SECTION 2: WAITING FOR PROCESSING

2.1 Wait - Wait 60 seconds

Purpose: Gives Vizard AI time to process videos and create clips

Settings:

• Amount: 60 seconds

Why do you need to wait:

• AI video analysis takes time
• Generating clips requires processing
• Transcription generation and virality analysis

2.2 HTTP Request1 - Project Status Check

Purpose: Gets analysis results and ready-made clips from Vizard AI

Settings:

• Method: GET
• URL: https://elb-api.vizard.ai/hvizard-server-front/open-api/v1/project/query/ {{$json.projectID}}
• Authentication: HTTP Header Auth (Vizard AI)

The answer with the clips ready:

{

“code”: 2000,

“message”: “success”,

“videos”: [

{

“title”: “Amazing moment from video”,

“VideoURL”: "https://example.com/clip1.mp4 “,

“transcript”: “This is the transcript of the viral moment... “,

ViralScore: 10,

“ViralReason”: “High engagement potential due to emotional content”,

“duration”: 15,

“StartTime”: 45,

EndTime: 60

},

{

“title”: “Another great clip”,

“VideoURL”: "https://example.com/clip2.mp4 “,

“transcript”: “Another interesting part... “,

ViralScore: 8,

“ViralReason”: “Contains trending topic”,

“duration”: 12,

“StartTime”: 120,

EndTime: 132

}

]

}

2.3 If - Readiness Test

Purpose: Checks if clips are ready for further processing

Condition:

• $json.code === 2000 (successful processing)

Logic:

• True: Let's move on to processing clips
• False: Back to waiting (Wait)

SECTION 3: PREPARING CLIPS

3.1 Edit Fields — Extract a video array

Purpose: Extracts an array of ready-made clips for further processing

Set settings:

{

}

]

}

3.2 Split Out - Split into separate clips

Purpose: Converts an array of clips into separate elements for individual processing

Settings:

• Field To Split Out: videos

• We save publication limits
• We improve the quality of content

3.4 Limit - Quantity limit

Purpose: Limits the number of clips that can be processed

Settings:

Transcription: {{$json.videos.transcript}}

Clip title: {{$json.videos.title}}

Viral reason: {{$JSON.videos.ViralReason}}

‍

System prompt:

You're an AI Agent for editing and creating titles and descriptions for viral tik tok video cuts.

You will receive a transcription and the reason for the virality of the video and, based on them, you must come up with a short but clear description/title for the tik tok video
