Length
60 seconds to 2.5 minutes. Teasers are often 30 to 60 seconds.
Levels and loudness
Trailers are mixed loud, but keep enough dynamic range for the setup to feel quiet.
Licensing
Creator and Studio cover client work, including trailers for films and games. The full terms are on the licensing page.
A workflow that works
- Write timings for each act
- Ask for the pause and button at the end
- Generate several climaxes and pick the best
- Ask for the hits to land harder in the prompt and regenerate
Avoid a flat arc. Without contrast, the climax will not feel big.
Prompts for film trailers
Epic trailer music, 2 minutes, quiet piano setup, ticking build from 0:40, huge orchestral climax at 1:30, silence then final hit
Dark thriller trailer, low synth drones, heartbeat pulse, braams on cuts, 90 seconds
Hopeful family film trailer, playful strings to a soaring orchestral finale, 60 seconds
