[Background Sound]:
- No background music. This video is a pure voiceover product sales short video, with no background music or sound effects throughout the whole process. It only retains the clear spoken Portuguese narration from a female speaker, accompanied by occasional rustling sounds of paper being flipped, to ensure the audience can focus on receiving science popularization and product-related information.
[Transition / Editing]:
- Smooth hard cuts are used to switch between different poster displays. Direct transitions are applied when inserting academic materials and hand-drawn science popularization illustrations. The overall editing rhythm matches the narration speed, and key frames stay long enough for the audience to receive information conveniently.
