About Add Music to Video
Last updated: May 2026
OptiPix Adicionar Música ao Vídeo permite sobrepor música de fundo, narração ou qualquer áudio a um vídeo. Faça upload de um vídeo e um arquivo de áudio, em seguida, controle o volume do áudio original do vídeo e da nova música. Escolha substituir o áudio original inteiramente ou misturá-los. Repita a música se ela for mais curta que o vídeo. Usa o filtro amix do FFmpeg.wasm.
How It Works
Filtro amix do FFmpeg.wasm para mixagem, ou -map para substituição. Ajuste de volume via filtro de volume.
Use Cases
- •Adicionar música de fundo a vlogs
- •Adicionar narração a gravações de tela
- •Substituir áudio em apresentações
- •Adicionar música a slideshows
- •Criar vídeo com trilha sonora personalizada
