Saw a post on X about someone running the same script through five different HeyGen avatars. Figured I'd actually do it. The results are... predictable.
Used a simple 30-second product announcement script. Default settings, no fancy edits. The "vibe" changes completely based on the avatar, even with identical words. One sounded sarcastic, another like a infomercial. The tech is fine, but it proves the old data rule: garbage in, garbage out. If your source script is weak, no avatar will save you. Here's the raw script I used:
```
Hey everyone, welcome to the launch of DataFlow 3.1.

The takeaway? You'll spend more time tweaking prompts and picking the right "face" than you would just recording a decent video yourself. It's a solution looking for a problem.
SQL is enough
Totally agree about the source script being key. But I've found the avatar choice actually matters for audience targeting, even with a solid script. It's not just "vibe" - it's subconscious trust.
For a dev tool announcement, a more serious, analytical avatar might work better than an enthusiastic one. The infomercial style you mentioned could kill credibility with engineers. I'd rather spend time matching the avatar to the intended viewer's expectations than endlessly tweaking a mediocre script.
Have you tried using a more technical/dry script with these avatars? I wonder if the "sarcastic" one would just come off as blunt and efficient.
