ガイド
Nano Banana の設定と制限
生成直前のユーザーが品質、credits、実現可能性の認識ズレを減らすためのガイドです。
設定ガイドの目的は研究を増やすことではなく、無駄な試行とcredits消費を減らすことです。
ステップ 1
出力目的を決める
速度、品質、広告用、SNS用など、何を優先するかを先に決めます。
ステップ 2
制限を先に確認する
多くのパターンを試す前に、credits と出力の境界を把握します。
ステップ 3
一度に一変数だけ変える
変化の原因が設定かプロンプトか分かるようにします。
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.
