A cup hits a table just as the narrator says the product name. If the clink swallows a syllable, a separate effects clip lets you turn it down while keeping the read intact.

Give the voice its own track

Start with a rough picture edit and decide which shot should carry each line. Higgsfield documents that Seed Audio 1.0 can create sound separately from the picture. Keeping the narration in short clips makes it easier to move one sentence when a shot changes length.

Place effects against visible actions

ElevenCreative Studio’s documentation describes positioning individual effects clips on the timeline. Mark the frame where the cup touches the table and align the start of the sound to that contact. Keep room tone separate if it needs to run under several cuts.

Listen through the full mix

Play the narration by itself to check its pacing, then listen with the effects and ambience. If an effect obscures a word, reduce its level and check the passage again. If you move the sound, watch the cut to see whether it still belongs to the action.
