What Problem Does It Solve?

Challenge

  • Daily news posting needs constant manual writing, editing, and uploading across multiple platforms.

  • Inconsistent tone and branding when multiple people summarize breaking news under time pressure.

  • No reliable audit trail: teams lose track of which story became which video and where it was posted.

Solution

  • Standardize a repeatable pipeline where each story becomes a caption plus avatar video, then publish everywhere from one place.

  • Use an AI captioning step with consistent prompt guardrails and a single avatar voice and style.

  • Store assets centrally and log metadata so every post can be traced, measured, and reused.

Frequently Asked Questions

No. You can run it manually using GPT-4o, HeyGen, and Postiz, then add automation later when volume grows.

Cost depends on video volume and plan tiers, but many teams start low and scale toward $30 to $120 per month as output becomes daily and multi-channel.

Breaking news can require human verification, and avatar videos may need a quick brand-safety review before publishing.

Yes, as long as your publisher supports the destination or provides an API. The core SOP stays the same: source news, generate script, render video, archive, log, then publish.

Fix a single prompt template, enforce length limits, and keep the same avatar and voice settings in HeyGen so every post feels like one show.

Any avatar-video generator plus any multi-channel scheduler can replace them, as long as you keep the same SOP boundaries between scripting, rendering, logging, and publishing.
