About Add Subtitles to Video
Last updated: May 2026
OptiPix Add Subtitles graba texto de subtítulos directamente en los píxeles del video. Sube un video y un archivo SRT, o escribe subtítulos manualmente con marcas de tiempo. Personaliza el tamaño de fuente y la posición. Los subtítulos se incrustan permanentemente: se muestran en cualquier reproductor sin archivos de subtítulos separados. Utiliza el filtro de subtítulos de FFmpeg.wasm.
How It Works
El filtro de subtítulos de FFmpeg.wasm -vf lee el archivo SRT y graba el texto en los fotogramas de video en las marcas de tiempo especificadas.
Use Cases
- •Añadir subtítulos para accesibilidad
- •Grabar subtítulos para redes sociales
- •Añadir traducciones a videos
- •Crear tutoriales subtitulados
- •Garantizar que los subtítulos se muestren en todas partes
