About Video Merger
Last updated: May 2026
OptiPix Video Merger combina 2-10 archivos de video en un solo video directamente en tu navegador. Sube videos, reordénalos y combínalos con manejo automático de formatos. Utiliza el demuxer concat de FFmpeg.wasm para una fusión rápida cuando los formatos coinciden, o re-codifica para formatos mixtos. Todo el procesamiento es local.
How It Works
El demuxer concat de FFmpeg.wasm une los videos. Los archivos del mismo formato usan -c copy para una fusión sin pérdidas; los formatos mixtos se re-codifican a H.264+AAC.
Use Cases
- •Combinar clips de video en uno
- •Fusionar segmentos de GoPro
- •Unir clips de entrevistas
- •Combinar clips de redes sociales
- •Fusionar grabaciones de presentaciones
