Pro Tips

1Start with the default Duration value and make small adjustments to understand how it affects your specific prompt style.
2Different styles respond differently to Duration changes — what works for photorealistic may not work for anime or abstract.
3Keep notes on which Duration values work best for your favorite prompt structures — this builds your personal Runway knowledge base.
4When sharing prompts, always include your Duration setting — it can dramatically change results even with identical prompt text.
5For batch generation, lock your Duration value to maintain consistency across an entire set of related images.

Common Mistakes

✕Using extreme Duration values without understanding the trade-offs — moderate values usually produce the most balanced results.

✕Assuming the same Duration value works for all styles — always test with your specific prompt before committing to a batch.

✕Changing Duration and other settings simultaneously — adjust one parameter at a time to understand each one's effect.
