Summary  
This chapter covers orchestrating a code workflow that chains multiple third-party API integrations for media generation and editing, while incorporating a human-in-the-loop step for review and template application.

General domain of usage  
AI video production

Generating a visual clone of yourself with AI is genuinely impressive by today's standards. Even people who work with AI every day are often surprised to learn that what they are watching is entirely AI-generated.

**HeyGen** is used to create the avatar and visual clone, while **Captions AI** handles the editing process, including captions, styling, cutaways, and final export. In the demo video, everything from the script to the avatar performance and final edit is produced with AI.

### Cost Expectations

Video generation is currently one of the most expensive AI tasks available to consumers. As a rough estimate, a 30-second avatar video can cost around **5 AUD** (approximately **3 to 4 USD**) to generate. It is worth keeping this cost in mind before getting started.

If HeyGen's pricing does not fit your budget right now, you can still follow along with the editing portion of this section using any existing video footage. The **Captions AI** workflow works with any source video and is not dependent on HeyGen-generated avatars.

The **Captions AI** subscription is a single monthly fee and is significantly more affordable than purchasing avatar generation credits.

Generate talking-head videos using an AI avatar

Clone your appearance and voice, generate videos from scripts, create content without recording new footage

Initial avatar and voice training required, then videos can be generated automatically

AI-powered video editing and post-production

Automatic captions, cutaway visuals, music mixing, video enhancement, one-click export

Requires a quick review and approval step to ensure the final edit meets quality standards

The pipeline in this section is: write a script, generate the HeyGen avatar video, download it, upload it to Captions AI, choose a template, export, and publish. The Captions AI step is the manual moment — it takes approximately two minutes. This is a deliberate choice, not a limitation.


- Understand the two-tool workflow: HeyGen for generation, Captions AI for editing
- Set realistic cost expectations for avatar video generation
-Know that the editing workflow applies to any video source, not just HeyGen
- Be ready to proceed to avatar creation in Chapter 2
