Quick path

Open BLOOB or Galaxy
Load audio and choose a scene
Set aspect (9:16 / 1:1 / 16:9 on Galaxy)
Press Record → stop → download

MP4 vs WebM

Browsers differ. Chrome/Edge often allow MP4 (H.264). Safari may fall back to WebM. Both are fine for most editors; convert WebM→MP4 with HandBrake if a platform rejects WebM.

Clean exports

Hide chrome while recording
On Galaxy, pick 1080p in Tune → Export
Keep the tab foregrounded — background tabs throttle FPS
Enable hardware acceleration in browser settings on Windows
