Tools they used
Cost: Gemini 4 Argon: from $2 in / $10 out per 1M tokens.
Set it up
Collect your inputs
List what goes in (raw footage, script, topic list or audio) and the exact output you want, for example 5 vertical clips under 45 seconds. Put inputs in one folder.
Set up the tools
Open Antigravity, Gemini 4 Argon. Connect accounts only where needed and note any per-minute or per-credit limits on the free plan before you start.
Run one piece end to end
Make a single output first. Check pacing, captions, voice and framing by watching it on a phone.
Turn it into a repeatable recipe
Save the prompts and settings that worked as a template so the next run takes minutes, then batch.
Review before you post
Watch every output before publishing. Check rights for music, likeness and footage, and label AI content where the platform requires it.
Copy the full setup prompt
Paste into your agent and it will walk you through the setup, asking before anything that sends, posts or spends.

Propose a step-by-step plan using these tools or cheaper alternatives, with the time and cost of each step. Use official pricing pages; say "check pricing" if unsure. 3.
