Nano Banana Video Settings and Limits
Use this guide when you are already close to generation and want fewer surprises around quality, credits, or feasibility.
The point of settings guidance is to reduce wasted runs, not to turn every generation into a research project.
Step 1
Define the output goal
Know whether you are optimizing for speed, social proof, ad creativity, or visual polish before changing settings.
Step 2
Check limits first
Review credit and output expectations before testing multiple variations, especially for client-facing work.
Step 3
Adjust one variable at a time
If the result changes, you should know whether length, prompt, or quality guidance caused it.
Practical notes
- Research mode should lead to a tool action, not replace it.
- Keep notes on which prompt changes actually improved output.
- Use the free page for onboarding questions and the pricing page for constraint questions.
The settings questions worth answering before a paid run
Users do not need a giant spec sheet. They need the few settings that actually change outcome, cost, and fit.
Know which settings matter first
Some settings change cost and output dramatically, while others can wait.
- Model choice decides duration, quality ceiling, and how quickly you can iterate.
- Aspect ratio should match the destination channel early so you do not validate a scene on the wrong canvas.
- Higher quality is worth paying for only after the prompt and composition are already stable.
Keep a live limit snapshot handy
Users checking settings and limits are often only one step away from purchase or generation.
- Veo 3.1 Fast currently runs at 8 seconds, 720p, and 100 credits per generation.
- Sora 2 Fast runs at 10 or 15 seconds, with 80 or 120 credits depending on duration.
- Sora 2 Pro adds 1080p quality mode, with credit cost rising as duration and quality increase.
Test in the right order
A simple testing sequence prevents a lot of unnecessary cost.
- Validate concept and motion with the faster or cheaper run before you upscale anything.
- Once the output direction is right, move to the higher-quality option for the final version.
- Keep a note of the winning prompt, aspect ratio, duration, and model so you do not rediscover the same setup later.
