Dynamic Videos let you record one video in Sendspark and personalize it at scale using AI voice cloning and dynamic backgrounds. You pick a keyword placeholder like “watermelon” that gets swapped for each recipient’s name, add a website or LinkedIn profile as the background, upload a CSV, and generate. Minutes consumed equal video length times the number of contacts.

​
Key takeaways

  • Record one video and personalize it at scale with AI voice cloning and dynamic backgrounds.
  • Use a keyword placeholder (e.g. “watermelon”) that Sendspark replaces with each recipient’s name; multiple languages are supported.
  • Keep videos 20 to 40 seconds and always set a fallback URL to avoid failed videos.
  • Minutes consumed = video length × number of contacts (for example, a 30-second video × 1,000 leads = 500 minutes).

​
Overview

Dynamic Videos in Sendspark let you record one video and personalize it at scale using AI voice cloning and dynamic backgrounds. This guide walks you through creating a campaign from start to finish.

​
Step 1 – Start a New Campaign

  1. Go to Dynamic Videos in your dashboard.
  2. Click Create New Campaign.
  3. Give your campaign a name (e.g., D Test).

​
Step 2 – Record or Upload a Video

  • Record a new video inside Sendspark.
  • Upload an existing video from your device.
  • Paste a video URL from Sendspark.
📌 Pro tip: Record in a quiet, well-lit space. Keep videos short (20–40 seconds) to maintain viewer attention.

​
Step 3 – Use AI Voice Cloning for Personalization

  • Choose a keyword placeholder (e.g., “watermelon”).
  • When generating videos, Sendspark will replace that keyword with each recipient’s name.
  • Example: “Hey watermelon, I’m Dan from tech support” → becomes → “Hey Bethany…” / “Hey Brandon…”
✅ Supports multiple languages.
✅ Add pauses after the name for smoother playback.

​
Step 4 – Customize Video Backgrounds

  • Dynamic Background: Insert a website or LinkedIn profile as the background.
  • Simulated Scrolling: Make it look like you’re browsing the site while speaking.
  • Mouse Cursor Animation: Add a moving cursor for realism.
📌 Fallback URL: If a background link is missing in your CSV, Sendspark will use this default link instead.

​
Step 5 – Select a Landing Page Template

  • Pick from existing templates or create a new one.
  • Add personalization tags (First Name, Company, Job Title).
  • Optionally embed a calendar or CTA button.

​
Step 6 – Upload a CSV File

  1. Download the sample CSV format.
  2. Include fields like:
  • First Name
  • Email
  • Background URL (website or LinkedIn profile)
  1. Upload your CSV to Sendspark.
  2. Map each column to the correct field.
📌 For LinkedIn campaigns: paste profile URLs into the background URL field.

​
Step 7 – Generate Videos

  • Click Generate.
  • Sendspark will show how many minutes you’ll consume and how many you have left.
  • Minutes = Video length × Number of contacts.
    • Example: 30-second video × 1,000 leads = 500 minutes.

​
Step 8 – Review and Share

  • Preview your personalized videos.
  • Share them:
    • Individually (copy link for Gmail, Outlook, LinkedIn messages).
    • As a campaign (share directly to email platforms).
  • Track performance in Campaign Analytics (opens, plays, clicks).

​
Step 9 – Optional Advanced Features

  • Lip Sync (Beta): Experimental feature that moves lips in sync with personalized names.
  • Combined Videos: Add longer follow-up videos without consuming extra minutes.

​
Best Practices

  • Keep videos 20–40 seconds.
  • Always add a clear call-to-action.
  • Use fallback URLs to avoid failed videos.
  • For large campaigns, double-check your CSV for missing data.
✅ That’s it! You’ve created a full Dynamic Video Campaign with Sendspark.
