Editor SFX Sparse
Requires
A running Scrollmark editor whose commands you can call: the SocialGPT editor chat, or scrollmark mcp from @scrollmark/cli for a coding agent. Search and import go through the editor's Freesound catalog. Without it, the when-to-use rules and the class table still guide sparse sound design by hand.
When
Load only when something is arriving (B-roll in, a title, a punch they asked to hit) or they asked for sound design. Speech-only recuts and interviews: do not place SFX.
Search and place
media_searchCatalog providerId: "freesound", kind: "audio". Pass sfxRole only for chip roles: hit whoosh riser reverse glitch foley ambience ui. Do not invent roles (pop click downer stinger drone drop explosion impact are not sfxRole). Extra query tokens AND; do not free-type "cinematic dark whoosh".
A sound the user names (mouse click, cork pop, ding, notification, camera shutter) is sfxRole: "ui" with the name as query ("cork pop"): the role adds no word of its own and only returns sounds of 0.3 s or more, long enough to hear over a voice.
Import a remoteId from that search and place it at the timeline second of the event in the same plan: media.importFromCatalog with "as": "$hit", then timeline.addMediaClip with mediaId: "$hit" and "as": "$sfx", then element.setParams with elementId: "$sfx" and params: { "volumePercent": 90 } (80–100; a one-shot under a voice needs 100, and louder is volume in dB). Keep hits short, but not shorter than 0.3 s: a 0.15 s click disappears under speech.
