About Add Music to Video
Last updated: May 2026
OptiPix Přidání hudby do videa vám umožní překrýt video hudbou na pozadí, hlasovým komentářem nebo jakýmkoli zvukem. Nahrajte video a zvukový soubor, poté ovládejte hlasitost původního zvuku videa i nové hudby. Zvolte, zda chcete původní zvuk zcela nahradit, nebo je smíchat dohromady. Pokud je hudba kratší než video, opakujte ji. Používá filtr FFmpeg.wasm amix.
How It Works
Filtr FFmpeg.wasm amix pro míchání, nebo -map pro nahrazení. Úprava hlasitosti pomocí filtru volume.
Use Cases
- •Přidat hudbu na pozadí k vlogům
- •Přidat hlasový komentář k nahrávkám obrazovky
- •Nahradit zvuk v prezentacích
- •Přidat hudbu k prezentacím
- •Vytvořit video s vlastním soundtrackem
