Credits guide
Google Flow Free Credits
Most users do not fail because of tool quality. They fail because they run out of credits too early. This page helps you plan output before you spend.
Cost per Clip
Quality, resolution, FPS, and clip length all change cost-per-output.
Renewal Risk
Free trials can convert to paid. Put reminders in place before expiration.
Simple planning workflow
- 1. Pick target clip length before your first generation batch.
- 2. Run a small quality test to estimate your effective credit cost per second.
- 3. Lock one workflow and scale only after cost is predictable.
- 4. Keep 15-20% credits as reserve for revisions and render failures.
Credit-saving defaults
- • Start with short clips and iterate prompt quality before extending duration.
- • Use consistent style templates to reduce failed generations.
- • Batch similar scenes together to lower rework volume.
- • Keep a prompt library of proven high-yield patterns.
FAQ
How many free credits do I get in Flow AI?
It depends on your route. Google publishes different free balances by region, eligibility, and plan tier, and these terms can change.
What is the fastest way to waste credits?
Generating long clips without a tested prompt workflow. Plan your clip length and preset before running full batches.
Can I carry unused credits to next month?
Rules vary by plan. Always check the latest official billing terms for rollover behavior.
Should I start with the calculator before generating?
Yes. A quick calculator estimate reduces trial-and-error and prevents early credit burn.
